Abstract
The present disclosure provide latch performance detecting method and a device. The method includes: extracting circuit structure information of a latch, having a transmission gate and a latch unit, an output terminal of the transmission gate is coupled to the input terminal of the latch unit, and the input terminal is coupled to the output terminal of the drive unit corresponding to the latch; the resistance value of the equivalent resistor of the latch is determined based on the circuit structure information, The first terminal of the equivalent resistor is the output terminal of the driving unit, and the second terminal is the input terminal of the latching unit; based on the resistance value of the equivalent resistor, the latching performance is determined. The embodiments of the present disclosure can accurately detect whether the latch is in a metastable state, which helps to improve the performance of the circuit.
