Description

[0002] Currently, semiconductor processes have developed to 3nm or even smaller nodes. As process nodes shrink, the minimum spacing of metal wiring is also shrinking, but chip wiring will face various problems and challenges. Conventional technology usually uses related wiring tools to achieve chip wiring. However, for macro cells in the chip, the metal layer and shape of the macro cell port vary depending on the process or supplier. Generally, in order to reduce the wiring density of a single metal layer and facilitate the wiring arrangement of the wiring tool, the ports of the macro cell will be on different metal layers. As the logical capacity of the macro cell increases, in order to control the physical size, the port positions overlap or cross, and the shape and arrangement of the ports change, which indirectly leads to the inability of the wiring tool to perform better wiring, and it is easy to cause DRC (Design Rule Check) violations at the port position.

[0057] The core of this application is to provide a macro cell winding method, which can effectively solve the DRC violation problem in the macro cell winding process and ensure the successful implementation of the macro cell winding; another core of this application is to provide a macro cell winding device, electronic equipment, computer-readable storage medium and computer program product, all of which have the above-mentioned beneficial effects.
[0058] In order to describe the technical solutions in the embodiments of the present application more clearly and completely, the technical solutions in the embodiments of the present application will be introduced below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.
[0059] An embodiment of the present application provides a macro unit wiring method.
[0060] Please refer to Figure 1 , Figure 1 This is a flow chart of a macro unit wiring method provided in the present application. The macro unit wiring method may include the following S101 to S105.
[0061] S101: Determine a target macro unit and each target port in the target macro unit.
[0062] This step is intended to determine the target macro cell and its target port. It is understandable that conventional wiring tools generally connect the signal ports of the macro cells in the chip to the circuit by wiring. Here, the target macro cell is the macro cell that needs to be connected to the circuit by wiring, and the target port is the macro cell signal port in the target macro cell that is connected to the circuit by wiring. Their number and deployment position in the metal layer are not unique. It should be pointed out that the macro cell generally refers to the RAM (Random Access Memory) unit or ROM (Read-Only Memory) unit in the chip. Of course, the chip may also contain other units besides macro cells, such as logic units.
[0063] S102: Acquire winding parameters of each target port, where the winding parameters include port parameters of the target port and metal layer parameters of the target metal layer to which the target port belongs.
[0064] This step aims to obtain the winding parameters of each target port. Specifically, for each target port in the target macro unit, its winding parameters may include port parameters and metal layer parameters. Among them, the port parameters may include but are not limited to the port name and port position of the target port; the metal layer parameters refer to the relevant parameter information of the target metal layer where the target port is located (the chip to which the target macro unit belongs generally includes multiple metal layers), which may include but are not limited to the metal layer level of the target metal layer, the metal layer winding direction, the minimum metal layer winding width, the minimum metal layer winding spacing, etc.
[0065] In one embodiment of the present application, obtaining the winding parameters of each target port may include executing a preset command in an electronic design automation tool to obtain the winding parameters of each target port. In other words, the winding parameters of the target ports may be automatically obtained using EDA (Electronics Design Automation) tool commands. For example, the EDA tool command "report_attribute $PIN" may be used to automatically capture the winding parameters of all target ports in a target macrocell.
[0066] S103: Determine a target winding metal layer of a target port according to the metal layer parameters, and determine winding data of the target port according to the port parameters and the metal layer parameters.
[0067] This step is intended to determine the target winding metal layer and winding data of the target port. Among them, the target winding metal layer is used to indicate the metal layer suitable for winding of the corresponding target port, which can be determined according to the metal layer parameters of the target port; the winding data is used to indicate the pre-winding information corresponding to the corresponding target port, such as pre-winding size, pre-winding position, pre-winding direction, etc. It should be pointed out that pre-winding here refers to pre-winding of each target port in the target macro unit. Generally speaking, the pre-winding position is close to the corresponding target port, the pre-winding size is small, and the pre-winding direction is perpendicular to the corresponding target port. Obviously, the essence of pre-winding is to preferentially fix the port winding part of the target macro unit.
[0068] In one embodiment of the present application, determining the target winding metal layer of the target port based on the metal layer parameters may include: determining whether the target metal layer is the minimum metal layer based on the metal layer parameters; if the target metal layer is the minimum metal layer, then using the upper metal layer of the minimum metal layer as the target winding metal layer of the target port; if the target metal layer is not the minimum metal layer, then using the target metal layer as the target winding metal layer of the target port.
[0069] The embodiment of the present application proposes a method for determining the target winding metal layer of a target port based on metal layer parameters. Specifically, in order to ensure the aesthetics of the chip winding and prevent the metal layer winding from being exposed on the chip's outer surface, for a target port deployed on the smallest metal layer, the metal layer above the smallest metal layer can be selected for winding, that is, the metal layer above the smallest metal layer is used as the target winding metal layer for this target port; for a target port deployed on other metal layers, the target port can be directly wound on the metal layer to which it belongs, that is, the target metal layer where the target port is located is directly used as its target winding metal layer.
[0070] In one embodiment of the present application, the winding data includes a pre-winding size and a pre-winding position; accordingly, determining the winding data of the target port based on the port parameters and the metal layer parameters may include: determining the port position of the target port based on the port parameters; determining the pre-winding size of the target port based on the metal layer parameters; determining the relative position of the pre-winding of the target port and the target port; determining the pre-winding position of the target port based on the port position, pre-winding size, and relative position.
[0071] The embodiment of the present application provides an implementation method for determining the winding data of the target port based on the port parameters and the metal layer parameters. Specifically, the winding data may include the pre-winding size and the pre-winding position, wherein the pre-winding size can be directly determined according to the metal layer parameters, while the pre-winding position needs to be determined in combination with the port position, the pre-winding size, and the relative position of the target port and the pre-winding. Among them, the port position of the target port can be directly obtained according to the port parameters, mainly referring to the position coordinates of the target port, such as the position coordinates of one or more vertices of the target port; the relative position of the pre-winding of the target port and the target port refers to the position deployment relationship between the target port and the pre-winding, such as the pre-winding and the target port are deployed perpendicular to each other, or tilted N degrees, etc. The specific implementation form can be customized by the technician.
[0072] Among them, determining the pre-winding size of the target port according to the metal layer parameters may include: determining the minimum winding width of the target winding metal layer according to the metal layer parameters, and using the minimum winding width as the pre-winding width; determining the spacing between the target port and the other nearest units according to the metal layer parameters, and determining the pre-winding length according to the spacing; determining the pre-winding size according to the pre-winding width and the pre-winding length.
[0073] The embodiment of the present application provides an implementation method for determining the pre-winding size of the target port based on the metal layer parameters. It should be pointed out that the pre-winding size should meet the size requirements of the corresponding metal layer for winding, including length and width, so as to avoid winding violation problems, i.e., DRC problems, as much as possible. Based on this, the minimum winding width of the target winding metal layer corresponding to the target port can be directly used as the pre-winding width, and the pre-winding length is set to be much smaller than the distance between the target port and the nearest other unit. Among them, the nearest other unit refers to the other unit in the chip that is closest to the target port of the target macro unit, such as a logic unit.
[0074] S104: Winding the target port on the target winding metal layer according to the winding data to obtain a pre-winding of the target port.
[0075] This step aims to achieve pre-routing of the target port. Specifically, for each target port in the target macro unit, after determining its corresponding target winding metal layer and winding data, the target port can be directly wound on the target winding metal layer according to the winding data to obtain its corresponding pre-routing.
[0076] S105: Perform complete routing on the pre-routing of all target ports to implement macrocell routing.
[0077] This step aims to achieve complete wiring of the target macro unit. Its essence is to complete the pre-wiring of each target port in the target macro unit, such as connecting it with other units outside the target macro unit, so as to achieve complete wiring of the target macro unit.
[0078] In one embodiment of the present application, the pre-winding of all target ports is fully wound to achieve macro unit winding, which may include: setting anti-optimization attributes for the pre-winding of all target ports; and using electronic design automation tools to fully wind each pre-winding after the attribute setting to achieve macro unit winding.
[0079] Specifically, the complete routing of the target macro unit can be achieved through EDA tools. However, before using the EDA tool to perform complete routing on the target macro unit, the anti-optimization attribute, that is, the "don't touch" attribute, can be set for each pre-routing in the target macro unit. This prevents the EDA tool from optimizing or deleting each pre-routing during the actual complete routing process, thereby maintaining the shape and position of each pre-routing.
[0080] It can be seen that the macrocell wiring method provided in the embodiment of the present application first determines each target port in the target macrocell that needs to be wound, and pre-wraps each target port according to the winding parameters of each target port, and then completes the winding of all pre-wraps, thereby realizing the macrocell winding operation. In other words, in the macrocell winding process, each port is first pre-wrapped to pre-fix the winding of the macrocell port, and then the entire macrocell is fully wound. This can avoid DRC violation problems caused by directly using conventional winding tools for macrocell winding when the shape and arrangement of the macrocell ports are irregular, further ensuring the successful implementation of macrocell winding.
[0081] Based on the above embodiments:
[0082] In one embodiment of the present application, after the pre-routing of all target ports is completely routed to realize the macro unit routing, it may also include: performing a routing design rule check on the target macro unit to determine whether there is a routing violation in the target macro unit; when there is a routing violation in the target macro unit, returning to the step of determining the target winding metal layer of the target port according to the metal layer parameters, and determining the routing data of the target port according to the port parameters and the metal layer parameters, until there is no routing violation in the target macro unit.
[0083] Specifically, after completing the macrocell routing, the target macrocell can also be subjected to a routing design rule check, i.e., a DRC violation check. Target macrocells with DRC violations can be re-routed to ensure that the target macrocells that have completed the routing no longer have DRC violation issues, further ensuring the successful implementation of the macrocell routing. When returning to S103 to re-route the routing, a technician can manually optimize the script strategy of S103 to optimize the routing data, such as optimizing the pre-winding size, pre-winding position, pre-winding direction, etc., to obtain an optimized pre-winding to avoid routing violation issues after the complete routing.
[0084] Among them, performing a winding design rule check on the target macro unit to determine whether the target macro unit has a winding violation may include: performing a winding design rule check on the target macro unit to determine whether the target macro unit has a winding short circuit, and determining that the target macro unit has a winding violation when the target macro unit has a winding short circuit; and / or performing a winding design rule check on the target macro unit to determine whether the target macro unit has a winding spacing violation, and determining that the target macro unit has a winding violation when the target macro unit has a winding spacing violation.
[0085] Specifically, macrocell routing violations in chips primarily include shorts and spacing violations. A short refers to a short circuit in the wiring at a macrocell port after it is connected to the circuit. A spacing violation refers to a spacing between wires that falls below the minimum standard, leading to signal crosstalk, electromigration, signal delays, and glitches. Therefore, when checking for routing violations in a target macrocell, these two aspects should be the primary focus.
[0086] Based on the above embodiments, an embodiment of the present application provides another macro unit wiring method.
[0087] Please refer to Figure 2 , Figure 2 This is a flow chart of another macro unit winding method provided in this application, and its implementation process is as follows:
[0088] 1. Write a script and use the EDA tool command "report_attribute $PIN" to capture the information (routing parameters) of all ports (PINs) in the target macro unit: port name, port coordinates, number of metal layers, metal layer winding direction, minimum metal layer winding width, minimum metal layer winding spacing, etc.
[0089] 2. Determine the names of all ports of the target macro unit {P1, P2, P3, ...} and the names of the connected wires {net1, net2, net3, ...}.
[0090] 3. Determine the coordinate information of all ports of the target macro unit {(llx1, lly1, urx1, ury1), (llx2, lly2, urx2, ury2), (llx3, lly3, urx3, ury3), ...}, where (llx1, lly1) represents the lower left corner coordinate of the first target port, (urx1, ury1) represents the upper right corner coordinate of the first target port, and the meaning of the remaining coordinates is similar, such as Figure 3 As shown, Figure 3 This is a schematic diagram of the principle of a pre-winding provided in this application.
[0091] 4. Determine the hierarchical names {M1, M2, M3, ...} of the metal layers where all ports of the target macro unit are located.
[0092] 5. Determine the metal layer routing directions {D1, D2, D3, ...} of the metal layers where all ports of the target macro unit are located.
[0093] 6. Determine the minimum routing width {W1, W2, W3, ...} and the minimum routing spacing {P1, P2, P3, ...} of the metal layer where all ports of the target macro unit are located.
[0094] 7. Set the width of the macro unit port pre-wrap to the minimum width of the metal layer winding corresponding to the current port {W1, W2, W3, ...}; set the length of the macro unit port pre-wrap to L. L can be set as a reference based on the spacing of the logic unit closest to the current port (L is much smaller than this spacing), or it can be adjusted according to the actual winding requirements of the project.
[0095] 8. Organize and summarize the data information determined in steps 2 to 7 above into the following array format:
[0096] set arrName(P1) {P1, net1, (llx1, lly1, urx1, ury1), M1, W1, P1, L1, D1};
[0097] set arrName(P2) {P2, net2, (llx2, lly2, urx2, ury2), M2, W2, P2, L2, D2};
[0098] set arrName(P3) {P3, net3, (llx3, lly3, urx3, ury3), M3, W3, P3, L, D1};
[0099] …
[0100] 9. According to the information obtained in step 8, loop through the values of each element P* of the array, and perform pre-winding according to the name of the port connection winding net*, port coordinates (llx*, lly*, urx*, ury*), metal layer P*, minimum winding width P*, pre-winding length L*, and winding direction D*. Write a script and use the EDA tool command "add_shape –width W* -status ROUTED –layer M* -net $net* -pathSeg {llx*, [expr lly*+[expr (ury* - lly*) / 2]], llx*+L*, lly*+W*}" to implement it. Among them, (llx*, [expr lly*+[expr (ury* - lly*) / 2]]) represents taking 1 / 2 of the current port shape as the lower left corner coordinate of the pre-winding, and (llx*+L*, lly*+W*) is the upper right corner coordinate of the pre-winding, so that the pre-winding result can be obtained as follows: Figure 3 shown.
[0101] 10. Based on the result of step 9, set the don't touch attribute for the pre-wound net so that the EDA tool cannot optimize or delete the pre-wound net during the actual winding process, and maintain the shape and position of the pre-wound. This allows the EDA tool to connect the actual winding and the pre-wound during the winding stage to complete the complete winding connection, such as Figure 4 As shown, Figure 4 This is a schematic diagram of the complete winding principle provided by this application.
[0102] 11. Perform a routing DRC check to determine whether there are still DRC routing short circuits or routing spacing violations in the macro unit port area. If there are problems, return to steps 9 and 10 and optimize the script strategy in step 9 until the routing short circuit or routing spacing violation problems are resolved.
[0103] It can be seen that the macrocell wiring method provided in the embodiment of the present application first determines each target port in the target macrocell that needs to be wound, and pre-wraps each target port according to the winding parameters of each target port, and then completes the winding of all pre-wraps, thereby realizing the macrocell winding operation. In other words, in the macrocell winding process, each port is first pre-wrapped to pre-fix the winding of the macrocell port, and then the entire macrocell is fully wound. This can avoid DRC violation problems caused by directly using conventional winding tools for macrocell winding when the shape and arrangement of the macrocell ports are irregular, further ensuring the successful implementation of macrocell winding.
[0104] An embodiment of the present application provides a macro unit winding device.

[0110] The complete winding module 5 is used to perform complete winding on the pre-winding of all target ports to obtain the actual winding of the target macro unit.
[0111] It can be seen that the macrocell winding device provided in the embodiment of the present application first determines each target port in the target macrocell that needs to be wound, and pre-wraps each target port according to the winding parameters of each target port, and then completes the winding of all pre-wraps, thereby realizing the macrocell winding operation. In other words, during the macrocell winding process, each port is first pre-wound to pre-fix the winding of the macrocell port, and then the entire macrocell is fully wound. This can avoid DRC violation problems caused by directly using conventional winding tools for macrocell winding when the shape and arrangement of the macrocell ports are irregular, further ensuring the successful implementation of macrocell winding.
