[0022] For ease of understanding, some of the professional content involved in this application is briefly described. In integrated circuit design, process corners refer to a series of limit values ​​that the electrical characteristics of transistors may reach under a specific manufacturing process. These limit values ​​usually include the fastest, slowest and typical device performance. Process corners are crucial to circuit design because they represent the performance fluctuations that actual chips may exhibit under different process conditions. Process corners may include TT (Typical NMOS Typical PMOS), FF (Fast NMOS Fast PMOS), SS (Slow NMOS SlowPMOS), etc., where NMOS and PMOS are both for N-type and P-type doping of different concentrations, Typical means that the transistor drive current is an average value, Fast means that the drive current is its maximum value, and Slow means that the drive current is its minimum value. By considering the process corners, the chip yield under specific process conditions can be estimated. Since TT represents the typical performance of the transistor, its parameter value is located at the center of the normal distribution, which can better reflect the performance of most devices. Therefore, the proportion of TT in the total chip is usually selected to calculate the yield to more accurately evaluate the manufacturing quality and reliability of most devices.

[0023] In order to enable those skilled in the art to better understand the technical solution of the present application, the technical solution of the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

The execution subject of the method can be an electronic device with computing function, such as a microcomputer, a server, and a mobile device such as a laptop computer and a tablet computer.

[0025] It should be noted that if there are substantially the same results, the method of the present application is not limited to Figure 1 The process sequence shown is limited.

[0026] In some possible implementations, the method may be implemented by a processor calling computer-readable instructions stored in a memory, such as Figure 1 As shown, the method may include the following steps:

[0027] S11: Acquire an initial operating voltage of the integrated circuit chip and an initial current of the integrated circuit chip when the integrated circuit chip operates according to the initial operating voltage.

[0028] Obtain the initial operating voltage of the integrated circuit chip, for example, determine the voltage of the relevant circuit in the chip as the initial operating voltage V c , the relevant circuits may be CPU, GPU, etc., that is, the initial operating voltage of the integrated circuit chip may be the core voltage (Core voltage) of the CPU. The initial current of the integrated circuit chip when the integrated circuit chip operates according to the initial operating voltage is obtained, for example, by measuring the initial operating voltage V c The corresponding current value is taken as the initial current I c .

[0029] S12: adjusting the initial operating voltage according to the initial current of the integrated circuit chip to obtain a target operating voltage.

[0030] According to the initial current of the integrated circuit chip, the initial operating voltage is adjusted to obtain the target operating voltage. For example, according to the initial current I c The size of can determine the current process corner of the integrated circuit chip, such as SS IC or FFIC, and then the initial operating voltage V c Increase or decrease to get the target operating voltage V' c , in order to adjust the process angle type.

[0031] When the integrated circuit chip operates at a target operating voltage, a target current of the integrated circuit chip is within a preset current range, and the initial current is outside the preset current range.

[0032] The operating current of the integrated circuit chip is within a preset current range, which may be the current value range required by the TT IC. The initial current is outside the preset current range, for example, the initial current is within the current value range corresponding to the SS IC or the FF IC, where the current range values ​​corresponding to the TTIC, SS IC, and FF IC are different. It can be understood that when the integrated circuit chip is operated according to the target operating voltage V' c When working, the working current of the integrated circuit chip is the target current I tc, target current I tc Within the preset current range, at this time, the target current I tc If the requirements of TT are met, the integrated circuit chip can be used as TTIC.

[0033] In this embodiment, the initial operating voltage of the integrated circuit chip and the initial current of the integrated circuit chip when the integrated circuit chip operates according to the initial operating voltage are obtained, and the initial operating voltage is adjusted according to the initial current of the integrated circuit chip to obtain a target operating voltage, wherein the target current of the integrated circuit chip is within a preset current range when the integrated circuit chip operates according to the target operating voltage, wherein the initial current is outside the preset current range, and the target voltage is obtained by adjusting the initial operating voltage according to the initial current of the integrated circuit chip, so that the target current of the integrated circuit chip is within the preset current range when the integrated circuit chip operates according to the target operating voltage, and the corresponding integrated circuit chip has stable characteristics, thereby improving the chip yield.

[0034] In some embodiments, the initial current is less than a minimum value of a preset current range and greater than a first preset value, or the initial current is greater than a maximum value of the preset current range and less than a second preset value, wherein the second preset value is greater than the first preset value.

[0035] Get the initial operating voltage V of the integrated circuit chip c And the initial current I of the integrated circuit chip when the integrated circuit chip works according to the initial working voltage c , based on the initial current I of the integrated circuit chip c , for the initial operating voltage V c Adjust to get the target operating voltage V' c , the integrated circuit chip is operated at the target voltage V' c When working, the working current of the integrated circuit chip is the target current I tc , target current I tc is within the preset current range.

[0036] In some examples, the current value of the integrated circuit chip is within the range of X mA to WmA (W>X>0), and the current value within the range of XmA to Y mA (W>Y>X) can be determined as the current value range corresponding to the SS IC, the current value within the range of YmA to ZmA (W>Z>Y>X) can be determined as the current value range corresponding to the TT IC, and the current value within the range of ZmA to WmA can be determined as the current value range corresponding to the FF IC. The preset current range can be the current value range corresponding to the TT, that is, YmA to ZmA. The initial current I c Less than the minimum value of the preset current range and greater than the first preset value, for example, XmA<I c<YmA, i.e. initial current I c The initial current is within the current value range corresponding to the SS IC. Alternatively, the initial current is greater than the maximum value of the preset current range and less than the second preset value, for example, ZmA<I c <WmA, that is, it is within the current value range corresponding to the FF IC. Among them, the first preset value is XmA, and the second preset value is WmA.

[0037] For example, if the current value of the integrated circuit chip is in the range of 0.6mA to 1.2mA, the current value in the range of 0.6mA to 0.8mA can be determined as the current value range corresponding to the SS IC, the current value in the range of 0.8mA to 1.0mA can be determined as the current value range corresponding to the TTIC, and the current value in the range of 1.0mA to 1.2mA can be determined as the current value range corresponding to the FF IC. The preset current range can be the current value range corresponding to the TT, that is, 0.8mA to 1.0mA. The initial current I c Less than the minimum value of the preset current range and greater than the first preset value, for example, 0.6 mA < I c <1.0mA, that is, the initial current I c The initial current is within the current value range corresponding to the SS IC. Alternatively, the initial current is greater than the maximum value of the preset current range and less than the second preset value, for example, 1.0 mA < I c <1.2mA, which is within the current value range corresponding to FF IC.

[0038] In some embodiments, the initial operating voltage is adjusted according to the initial current of the integrated circuit chip to obtain the target operating voltage, including: in response to the initial current being less than the minimum value of the preset current range and greater than the first preset value, the initial operating voltage is boosted to obtain the target operating voltage.

[0039] Based on the initial current I of the integrated circuit chip c , for the initial operating voltage V c Adjust to get the target operating voltage V' c , where, in response to the initial current I c is smaller than the minimum value of the preset current range and larger than the first preset value. For example, the preset current range is Y mA to Z mA, and the first preset value is X mA. If X mA < I c <Y mA, it can be determined that the current integrated circuit chip is a SS IC, and then the initial operating voltage V c Perform boost adjustment to obtain a voltage higher than the initial operating voltage V c Large target operating voltage V' c Furthermore, the integrated circuit chip is operated at a target operating voltage V' cThe operation is performed so that the operating current of the integrated circuit chip after the boost is within the preset current range, that is, the target current I tc Within Y mA~Z mA.

[0040] Further, in some embodiments, the initial operating voltage is boosted to obtain a target operating voltage, including: gradually increasing the initial operating voltage according to a preset ratio; obtaining a current current of the integrated circuit chip, wherein the current current is the current of the integrated circuit chip when the integrated circuit chip operates according to the current boost-adjusted operating voltage; in response to the current current being within a preset current range, determining the current boost-adjusted operating voltage as the target operating voltage.

[0041] In some examples, the initial operating voltage V c The initial working voltage V is gradually increased, that is, within the adjustable voltage range of the integrated circuit chip, the initial working voltage V is increased according to a fixed ratio or a non-fixed ratio. c For example, if the adjustable voltage range is ±10%, the initial working voltage V can be increased by 2%, 4%, 6%, 8%, and 10%. c The initial working voltage V can be increased gradually, or by 1%, 2%, 5%, 7%, 10%. c The integrated circuit chip works according to the current working voltage after the boost adjustment, and then obtains the current current I' of the integrated circuit chip. c For example, the initial working voltage V is increased by 1%, 2%, 5%, 7%, or 10%. c When the current I' is gradually increased c Can be integrated circuit chip according to 101% V c The current during operation is 102%V c The current during operation is 110%V c The current when working. Further, if the current I' c If the current is within the preset current range, the current I' c The corresponding boosted operating voltage is determined as the target operating voltage. For example, when the integrated circuit chip is 101% V c The current during operation is within the preset current range, and 101% V c The target operating voltage is determined so that the integrated circuit chip after boosting also has stable characteristics.

[0042] For example, the initial operating voltage V c The initial working voltage V is 0.8V, and the initial working voltage V is increased by 1%, 2%, 5%, 7%, and 10%. cThe voltage is gradually increased to 0.808V, 0.816V, 0.840V, 0.856V and 0.880V. The integrated circuit chip operates according to the current working voltage after the boost adjustment, and then the current current I' of the integrated circuit chip is obtained. c For example, the integrated circuit chip operates at 0.808V and obtains the current I' c1 , if the current I' c1 If the current is within the preset current range, the current I' c1 The corresponding 0.808V is the target operating voltage. If the current I' c1 It is not within the preset current range. Further, the integrated circuit chip works at 0.816V to obtain the current current I' c2 , if the current I' c2 If the current is within the preset current range, the current I' c2 The corresponding 0.816V is the target operating voltage.

[0043] It can be understood that by gradually increasing the initial operating voltage so that when the SS IC operates at the target voltage, the corresponding target current is within the preset current range, the SS IC can be used as a TT IC, thereby improving the chip yield.

[0044] In some embodiments, the initial operating voltage is adjusted according to the initial current of the integrated circuit chip to obtain the target operating voltage, including: in response to the initial current being greater than the maximum value of a preset current range and less than a second preset value, the initial operating voltage is reduced in pressure to obtain the target operating voltage.

[0045] Based on the initial current I of the integrated circuit chip c , for the initial operating voltage V c Adjust to get the target operating voltage V' c , where, in response to the initial current I c is greater than the maximum value of the preset current range and less than the second preset value. For example, the preset current range is Y mA to Z mA, and the second preset value is W mA. If Z mA < I c <W mA, that is, the current integrated circuit chip can be determined to be FF IC, and then the initial working voltage V c Perform pressure reduction adjustment to obtain a voltage lower than the initial operating voltage V c Small target operating voltage V' c Furthermore, the integrated circuit chip is operated at a target operating voltage V' c The operation is performed so that the operating current of the integrated circuit chip after the pressure reduction is within the preset current range, that is, the target current I tcWithin Y mA~Z mA.

[0046] In some embodiments, an initial operating voltage is decompressed to obtain a target operating voltage, including: gradually reducing the initial operating voltage according to a preset ratio; obtaining a current current of the integrated circuit chip, wherein the current current is the current of the integrated circuit chip when the integrated circuit chip operates according to the current decompressed and adjusted operating voltage; in response to the current current being within a preset current range, determining the current decompressed and adjusted operating voltage as the target operating voltage.

[0047] In some examples, the initial operating voltage V c The initial working voltage V is gradually reduced, that is, within the adjustable voltage range of the integrated circuit chip, the initial working voltage V is adjusted according to a fixed ratio or a non-fixed ratio. c For example, if the adjustable voltage range is ±10%, the initial working voltage V can be adjusted by -2%, -4%, -6%, -8%, and -10%. c The initial operating voltage V can be gradually reduced, or it can be adjusted by -1%, -2%, -5%, -7%, -10%. c The integrated circuit chip works according to the current working voltage after the pressure reduction adjustment, and then obtains the current current I' of the integrated circuit chip. c For example, the initial working voltage V is adjusted by -2%, -4%, -6%, -8%, -10%. c When the current I' is gradually reduced c It can be an integrated circuit chip according to 98% V c The current during operation is 96%V c Current during operation...90%V c The current when working. Further, if the current I' c If the current is within the preset current range, the current I' c The corresponding operating voltage after decompression adjustment is determined as the target operating voltage. For example, when the integrated circuit chip is adjusted according to 96% V c The current during operation is within the preset current range, and 96% V c The target operating voltage is determined so that the integrated circuit chip has stable characteristics after decompression.

[0048] For example, the initial operating voltage V c The initial working voltage V is 0.8V, and the initial working voltage V is adjusted by -1%, -2%, -5%, -7%, and -10%. cThe integrated circuit chip operates according to the current working voltage after the pressure reduction adjustment, and then obtains the current current I' of the integrated circuit chip. c For example, the integrated circuit chip operates at 0.792V and obtains the current I' c1 , if the current I' c1 If the current is within the preset current range, the current I' c1 The corresponding 0.792V is the target operating voltage. If the current I' c1 It is not within the preset current range. Further, the integrated circuit chip works at 0.784V to obtain the current current I' c2 , if the current I' c2 If the current is within the preset current range, the current I' c2 The corresponding 0.784V is the target operating voltage.

[0049] It can be understood that by gradually reducing the initial operating voltage so that when the FF IC operates at the target voltage, the corresponding target current is within the preset current range, then the FF IC can be used as a TT IC, thereby improving the chip yield.

[0050] In some embodiments, when the integrated circuit chip operates according to the target operating voltage, the operating voltage of the circuit in the integrated circuit chip is within a corresponding voltage range.

[0051] In some examples, according to the initial current I c , for the initial operating voltage V c Adjust to get the target operating voltage V' c , the integrated circuit chip is operated at the target voltage V' c When working, the operating voltage of the circuit in the integrated circuit chip is within the corresponding voltage range, wherein the circuit in the integrated circuit chip may include a digital circuit and / or an analog circuit. That is, the integrated circuit chip operates at the target operating voltage V' c Work is performed to determine the target current I tc When the power supply voltage of each circuit in the integrated circuit chip is lowered, each circuit in the integrated circuit chip can still work normally, that is, the specific power supply voltage of each circuit needs to meet the design specification requirements. Among them, test cases can also be designed to detect whether each circuit module can work normally.

[0052] Further, in some embodiments, the target operating voltage is written into a target circuit of the integrated circuit chip.

[0053] By the initial operating voltage V cAdjust to get the target operating voltage V' c , so that the integrated circuit chip according to the target operating voltage V' c When working, the working current of the integrated circuit chip is the target current I tc， Target current I tc Further, the target operating voltage V' c Write the target circuit of the integrated circuit chip, for example, the target operating voltage V' c Write to a fixed space in the chip that cannot be easily rewritten, for example, it can be written into the eFuse of the chip. When using the integrated circuit chip, the target operating voltage V' can be read from the target circuit c , as the actual operating voltage of the chip to improve the stable performance of the chip.

According to the initial current I c The size of the current process corner of the integrated circuit chip can be determined, for example, based on the initial current I c Determine whether the chip is a SS IC or a FF IC, and then adjust the initial operating voltage V c Increase or decrease.

[0057] S23: Determine whether the chip can work normally, that is, determine whether the chip can work normally based on the increased or decreased operating voltage.

[0058] If one of the judgment results of step S23 is that the chip cannot work normally based on the increased or decreased working voltage, then step S22 is executed to continue adjusting the chip voltage. Alternatively, if the chip cannot work normally based on the increased or decreased working voltage, the entire voltage adjustment process can be terminated directly (not shown in the figure).

[0059] The second judgment result of step S23: if the chip can work normally based on the increased or decreased working voltage, then step S24 is executed.

[0060] S24: Obtain the working current of the chip. In response to the chip being able to work normally based on the increased or decreased working voltage, obtain the corresponding working current I' c .

[0061] S25: Determine whether the working current is within the preset current range. Determine the working current I' c Whether it is within the preset current range, for example, to determine whether the working current I' c Is it within the current range required by the TT IC?

[0062] If one of the judgment results of step S25 is that the operating current is not within the preset current range, step S22 is executed to continue adjusting the chip voltage.

[0063] The second judgment result of step S25: if the working current is within the preset current range, then step S26 is executed.

[0064] S26: Save the target voltage. For example, the operating current I' c The corresponding adjusted voltage is used as the target voltage V' c Write into the chip.
