NuSMV Simulation Using Random Traces

I am attempting to run "random" or non-deterministic simulations of a NuSMV model I have created. However between subsequent runs the trace that is produced is exactly the same. Here is the model: MODULE main VAR x : 0..4; VAR clk : 0..10; DEFINE…

Are there options that would boost the amount of memory that NuSMV can use during a specification run?

During specification running in nusmv, it takes several hours and eventually gives the result of "killed 9". How to speed up the execution? Are there options that would boost the amount of memory that NuSMV can use during a specification run?

Model checking with NuSMV

Is it true that in NuSMV there is no value like NULL, nil, None? And that we should not make a model for a process because the models should repesent electronic circuits? My scenario is that I have one UART connector, a main memory and a process…
