Description

Technical Field

[0001] The present invention relates to the field of integrated circuit analysis, and in particular to an analysis method, device, equipment and medium for strengthening the reliability of radiation-resistant circuits. Background Art

[0002] When particles hit microelectronic devices, the most sensitive area is usually the reverse biased PN junction. This is because the high field in the depletion region of the reverse biased junction can very effectively collect particle induced charges through the drift process, thereby generating a transient current at the junction contact. Taking a CMOS inverter as an example, when the output is 1, the drain of the N-type transistor is the most sensitive area. When a particle hits, it will collect negative charges, forming a transient current, and the inverter output will experience a 1 to 0 voltage jump; similarly, when the output is 0, the drain of the P-type transistor is a sensitive area. When hit by a particle, it will collect positive charges, forming a transient current, and the inverter output will experience a 0 to 1 voltage jump.

[0003] In the field of radiation-hardened circuit design, in order to improve the radiation resistance of the circuit and reduce the possibility of errors after the circuit is hit by particles, radiation hardening by design (RHBD) is a common method.

[0039] The drawings described herein are used to provide a further understanding of the present invention and constitute a part of the present invention. The exemplary embodiments of the present invention and their descriptions are used to explain the present invention and do not constitute an improper limitation of the present invention.

[0045] In order to clearly describe the technical solutions of the embodiments of the present invention, in the embodiments of the present invention, words such as "first" and "second" are used to distinguish the same items or similar items with basically the same functions and effects. For example, the first threshold and the second threshold are only used to distinguish different thresholds, and their order is not limited. Those skilled in the art can understand that words such as "first" and "second" do not limit the quantity and execution order, and words such as "first" and "second" do not necessarily limit them to be different.

[0046] It should be noted that, in the present invention, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present invention should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0047] In the present invention, "at least one" means one or more, and "plurality" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the associated objects before and after are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, at least one of a, b or c can mean: a, b, c, the combination of a and b, the combination of a and c, the combination of b and c, or the combination of a, b and c, where a, b, c can be single or multiple.

[0048] After a radiation-hardened circuit structure is designed, its reinforcement reliability needs to be analyzed.

[0049] In order to analyze the reliability of the structure of the radiation-resistant reinforced circuit, one existing method is to classify and discuss each node of the radiation-resistant circuit structure, analyze each possible voltage jump situation, and record the impact of each situation on the stability of the circuit structure. However, this method requires discussing the jump from low potential to high potential and from high potential to low potential of each node separately, and then analyzing the impact on each transistor. This process is cumbersome and time-consuming. Another method is to simulate the possible voltage reversal situation through simulation software, and analyze the reliability of the radiation-resistant circuit structure based on the simulation results, but this method cannot directly reflect the topological structure of the circuit, and it is difficult to improve the circuit.

[0050] In order to solve the defects in the prior art, the present application provides an analysis method, device, equipment and medium for strengthening the reliability of radiation-resistant circuits, which are described in detail one by one in the following embodiments.

[0051] The present application embodiment first provides a method for analyzing the reliability of radiation-resistant circuit reinforcement. Please refer to Figure 1 , Figure 1 A flow chart of the analysis method for enhancing the reliability of radiation-resistant circuits provided in an embodiment of the present application.

[0052] like Figure 1 As shown, the analysis method for strengthening the reliability of the anti-radiation circuit includes the following S101 to S102:

[0053] S101 , determining, according to the circuit structure of the anti-radiation circuit, a control relationship between storage nodes of the anti-radiation circuit in different states.

[0054] Radiation Hardened Circuit refers to electronic circuits that have taken special measures during the design and manufacturing process to improve their reliability and performance in radiation environments. These circuits can work normally in high radiation environments and reduce failures and performance degradation caused by radiation. Radiation Hardened Circuits are widely used in aerospace, nuclear industry, military and other fields that need to work in extreme radiation environments.

[0055] In actual applications, after writing to a storage / memory circuit, all storage nodes in the circuit will be at two different potentials depending on the written information (0 or 1). When the circuit is hit by particles, the potentials of these nodes may change, causing the storage information of the circuit to change.

[0056] After being hit by particles, the radiation-resistant circuit can resist the impact of the particle impact to a certain extent, so that the storage information of the circuit does not change.

[0057] The different states of the anti-radiation circuit refer to the state of the circuit after 0 or 1 is written in the circuit. After 0 is written in the circuit, all storage nodes will be at a certain potential. At this time, the state of the anti-radiation circuit is recorded as 0. Similarly, after 1 is written in the circuit, all storage nodes will be at another certain potential. At this time, the state of the anti-radiation circuit is recorded as 1.

[0058] Specifically, in the embodiment of the present application, determining the control relationship between the storage nodes of the anti-radiation circuit in different states according to the circuit structure of the anti-radiation circuit includes:

[0059] When the anti-radiation circuit is in the first state, taking any storage node in the anti-radiation circuit as a first storage node, and judging whether a second potential of a second storage node is determined by a first potential of the first storage node based on a circuit structure of the anti-radiation circuit;

[0060] When the second potential of the second storage node is determined by the first potential of the first storage node, determining that when the anti-irradiation circuit is in the first state, the first storage node has a positive contribution to the potential of the second storage node;

[0061] When the anti-irradiation circuit is in the second state, any storage node in the anti-irradiation circuit is used as a third storage node, and based on the circuit structure of the anti-irradiation circuit, it is determined whether a fourth potential of a fourth storage node is determined by the second potential of the fourth storage node;

[0062] In the case where the fourth potential of the fourth storage node is determined by the third potential of the third storage node, it is determined that when the anti-irradiation circuit is in the second state, the third storage node has a positive contribution to the potential of the fourth storage node. For example, assuming that the storage nodes of an anti-irradiation circuit are named storage nodes A, B, C, ... in sequence, wherein the storage node A is connected to the gate of the P-type transistor between the storage node B and the power supply, after writing 0 to the circuit, the potential of the storage node A is 0, in which case, the potential of the storage node A turns on the potential pull-up or pull-down transistor of the storage node B, so that the potential of the storage node B is 1, in which case, it is considered that the storage node A has a positive contribution to the potential of the storage node B.

[0063] In an optional implementation of the present application, the control relationship between the various storage nodes of the anti-radiation circuit can be represented based on a control relationship diagram of the anti-radiation circuit, so as to facilitate subsequent analysis of the anti-radiation circuit reinforcement reliability based on the control relationship diagram.

[0064] For further information, please refer to Figure 2 and Figure 3 , Figure 2 A circuit structure diagram of an anti-radiation circuit provided in an embodiment of the present application; Figure 3 A storage node control relationship diagram of a radiation-resistant circuit provided in the present application.

[0065] like Figure 2 As shown, Figure 2 It is a dual interlocked storage cell structure (DICE) in a classic radiation-resistant circuit.

[0066] In Figure 2After 0 is written into the anti-radiation circuit shown (ie, the anti-radiation circuit is in the 0 state), Figure 2 The potentials of the storage nodes A, B, C, and D shown in FIG. are 0, 1, 0, and 1 respectively; Figure 2 After 1 is written into the anti-radiation circuit shown (ie, the anti-radiation circuit is in the 1 state), Figure 2 The potentials of the storage nodes A, B, C, and D shown in the figure are 1, 0, 1, and 0, respectively.

[0067] When the anti-radiation circuit is in the 0 state, the potential of the storage node A is 0, so that the P-type transistor above the storage node B is turned on. Therefore, the potential of the storage node B is 1. That is, when the anti-radiation circuit is in the 0 state, the storage node A has a positive contribution to the potential of the storage node B. At this time, Figure 3 In the control relationship diagram shown, there is a solid arrow starting from storage node A and ending at storage node B. At the same time, when the potential of storage node B is 1, the N-type transistor under storage node A is turned on, thereby making the potential of storage node A 0, that is, when the anti-irradiation circuit is in the 0 state, storage node B has a positive contribution to the potential of storage node A. At this time, Figure 3 The control relationship diagram shown has a solid arrow starting from storage node B and ending at storage node A.

[0068] For storage node C and storage node D, when the anti-radiation circuit is in the 0 state, the potential of storage node C is 0, so that the P-type transistor above storage node D is turned on, and the potential of storage node D is 1, that is, when the anti-radiation circuit is in the 0 state, storage node C has a positive contribution to the potential of storage node D. At this time, Figure 3 In the control relationship diagram shown, there is a solid arrow starting from the storage node C and ending at the storage node D; at the same time, when the potential of the storage node D is 1, the N-type transistor below the storage node C is turned on, thereby making the potential of the storage node C 0, that is, when the anti-irradiation circuit is in the 0 state, the storage node D has a positive contribution to the potential of the storage node C. At this time, Figure 3 In the control relationship diagram shown, there is a solid arrow starting from storage node D and ending at storage node C.

[0069] The same analysis method is used to obtain the control relationship between different storage nodes when the circuit is in state 1, and then the following can be obtained: Figure 3 The control relationship shown by the hollow arrows shown. I will not repeat it here. The difference from the control relationship diagram when the circuit is in state 0 is that when the circuit is in state 0, the control relationship between different storage nodes is represented by solid arrows; when the circuit is in state 1, the control relationship between different storage nodes is represented by hollow arrows.

[0070] S102: Analyze the anti-radiation circuit reinforcement reliability based on the control relationship between the storage nodes in the different states.

[0071] Specifically, the above S102 includes:

[0072] Based on the control relationship between each of the storage nodes in different states, the reliability of each of the storage nodes in the anti-radiation circuit is determined; when any of the storage nodes is unreliable, the anti-radiation circuit is determined to be unstable; when all of the storage nodes are reliable, the anti-radiation circuit is determined to be reliable.

[0073] Wherein, determining the reliability of each storage node in the radiation-resistant circuit based on the control relationship between each storage node in different states includes:

[0074] For a fifth storage node in the anti-radiation circuit, based on the control relationship between the storage nodes in different states, determining whether the sixth storage node has a positive contribution to the potential of the fifth storage node when the anti-radiation circuit is in the first state;

[0075] and, determining whether the fifth storage node has a positive contribution to the potential of the sixth storage node when the anti-irradiation circuit is in the second state;

[0076] When the anti-irradiation circuit is in the first state, the sixth storage node has a positive contribution to the potential of the fifth storage node, and when the anti-irradiation circuit is in the second state, the fifth storage node does not have a positive contribution to the potential of the sixth storage node, the fifth storage node is determined to be reliable.

[0077] That is, when the radiation-resistant circuit is in different circuit states, when all storage nodes are reliable nodes, the radiation-resistant circuit is a reliable circuit. In this case, if the radiation-resistant circuit is impacted by particles, the potential of the changed storage node can be restored by another storage node with which it has a control relationship after the impact ends.

[0078] For example, please refer to Figure 3 When the anti-radiation circuit is in the first state, the potentials of all storage nodes are in the first state, that is, the potential of storage node A is 0, the potential of storage node B is 1, the potential of storage node C is 0, and the potential of storage node D is 1.

[0079] When the potential of storage node A is impacted by particles and changes from potential 0 to potential 1, storage node A will change from the first state to the second state, and the positive contribution of storage node A to storage node B will also change to the positive contribution to storage node D. In this case, the potential of storage node D will also change from potential 1 to potential 0, and storage node D will also change from the first state to the second state. Since in the second state, storage node D only has a positive contribution to storage node A, storage node A also only has a positive contribution to storage node D. Therefore, even if storage node A and storage node D both enter the second state, storage node B and storage node C are still in the first state.

[0080] Because in the first state, storage node B only has a positive contribution to storage node A, storage node C also only has a positive contribution to storage node D, and the potentials of storage node B and storage node C have never changed. Therefore, the potential of storage node A will be restored from potential 1 to potential 0 by storage node B, and the potential of storage node D will be restored from potential 0 to potential 1 by storage node C. In summary, the analysis method of the anti-radiation circuit reinforcement reliability provided in the embodiment of the present application determines the control relationship between each storage node of the anti-radiation circuit under different states according to the circuit structure of the anti-radiation circuit; then, the reinforcement reliability of the anti-radiation circuit is analyzed in combination with the control relationship between each storage node. This method can directly reflect the topological structure of the anti-radiation circuit in combination with the circuit structure of the anti-radiation circuit, and improve the anti-radiation circuit when the reinforcement reliability of the anti-radiation circuit needs to be improved. At the same time, this method does not need to discuss the potential jump of each storage node separately, and then analyze the impact of each transistor, which is conducive to improving the analysis efficiency of the anti-radiation circuit reinforcement reliability analysis.

[0089] When the fourth potential of the fourth storage node is determined by the third potential of the third storage node, it is determined that the third storage node has a positive contribution to the potential of the fourth storage node when the anti-irradiation circuit is in the second state.

[0100] and, determining whether the fifth storage node has a positive contribution to the potential of the sixth storage node when the anti-irradiation circuit is in the second state;

[0101] When the anti-irradiation circuit is in the first state, the sixth storage node has a positive contribution to the potential of the fifth storage node, and when the anti-irradiation circuit is in the second state, the fifth storage node does not have a positive contribution to the potential of the sixth storage node, and the fifth storage node is determined to be reliable. In an optional implementation of the present application, the first state of the anti-irradiation circuit is state 1, and the second state of the anti-irradiation circuit is state 0.
