This disclosure relates to signal observability rating. In an example, a method can include propagating a clock signal through a respective module of a circuit design in a forward and backward direction, evaluating clock signal propagation results for the respective module based on a forward and backward clock signal propagation of the clock signal to compute an observability rating for a data signal to be processed by the respective module during formal verification, and updating a current observability rating of the respective property for the data signal to the computed observability rating.

Systems and methods for signal observability rating

Various embodiments provide for analyzing (e.g., debugging) waveform data generated for a simulated circuit design, which can be used as part of electronic design automation (EDA). For example, where a user modifies a circuit design in a manner that impacts a next simulation run performed on the circuit design, various embodiments perform the next simulation run only on one or more portions of the circuit design affected by the user's modifications, while the results/simulated values for the rest of the circuit design are kept or reused.

Analyzing waveform data generated for simulated circuit design

In the described examples, a model impact monitor can include an electronic design automation (EDA) manager that communicates with a plurality of EDA programs, wherein each EDA program generates a model set for a register-transfer level (RTL) design comprising a list of RTL operations. The model impact monitor can also include an adaptive model interface that records changes to the RTL operations of the RTL design and measures a change in performance characteristics of each of the plurality of EDA programs based on a respective one of the changes in the RTL operations of the RTL design.
