Abstract

The embodiment of the invention provides a circuit detection method and device, a storage medium and electronic equipment. The circuit detection method comprises the following steps: obtaining a delay table corresponding to a target circuit to be detected, the delay table storing reference delays of a plurality of different types of logic units under a fan-out load, the logic units having the same PVT parameters as the target circuit; querying the delay table according to the type information of the signal output by the target circuit at a preset node and the fan-out load so as to obtain the reference delay of the corresponding target logic unit under the corresponding fan-out load; obtaining a time margin measurement value of the target circuit at the preset node; and judging whether the target circuit is qualified or not according to the time margin measurement value and reference delay. According to the invention, the design iteration can be accelerated, and the optimal margin is obtained to ensure the stability and the optimal performance of the circuit.

Description

technical field [0001] The present application relates to the field of circuit detection, in particular to a circuit detection method, device, storage medium and electronic equipment. Background technique [0002] In the design process of IP (intellectual property core) circuits, margin QA (margin quality inspection) is an indispensable part. Margin QA includes not only the inspection of timing margin, but also the quality inspection of signal transmission time (transition time). The quality of timing margin and transit time determines the performance and stability of a circuit design. The larger the time margin at critical timing nodes, the better the stability of the circuit function, but the performance is not optimal. The signal transmission time is short, the circuit function performance is good, and the stability is good, but the size of the driver is large, the area is large, and the dynamic power consumption is large. [0003] In order to ensure the yield rate of ...
