Functional Simulation using UPF (Cont’d)

Last week we saw how UPF is written from verification perspective and today lets see what information from simulator will help debug the issues. First lets look at some of the information printed out by simulator when UPF is enabled. Automatic Assertions Synthesized: (1) INFO : Sleep Signal value changed. SleepSignal SLEEP corresponding to signal […]

Functional Simulation using UPF (Cont’d)

Last week we discussed the various ways UPF can be used to model functional behaviour of a Mult-Voltage/Power Gating design. This week lets look at the following: (1) Voltage ramps, and (2) How will the simulator flag a violation, when some activity is triggered during the ramping up cycle or ramping down cycle? (3) How […]
