Transistor Level Critical Path Analyzer

PathInspector automatically identifies the critical path and enables designers to analyze the critical path with highest precision.

Transistor level circuit simulation is the essential step of the integrated circuit (IC) design. However, it is generally impractical to simulate the entire SoC at the transistor level. Designers need to identify the critical path and should be able to analyze the selected critical path with highest accuracy within the limited design time.
