Re: [tlaplus] Checking Liveness on Windows



In that case checking liveness is equivalent to checking the statement

SpecInit /\ [][SpecNext]_vars /\ SpecLiveness => SpecLiveness

Which is vacuously true. What you want is to check SpecInit /\ [][SpecNext]_vars as a your temporal formula and then make SpecLiveness a temporal property in the IDE.

True exactly, I have set the comobox to "Temporal formula" and I have indicated MySpec.

Just a wild guess: did you indicate `MySpec' (instead of the default `Spec') as the specification of your system in the TLC pane of the Toolbox?

Hi everyone,

I am using toolbox version 1.6.0 of 10 July on Windows 10 1909.

I have defined my spec to be like this:
MySpec ==
/\ SpecInit
/\ [][SpecNext]_vars
/\ SpecLiveness

The problem is that the model checker does not check liveness at all, unless I remove /\ SpecLiveness from the spec definition above!!!

Why is this happening? Please help me.
