Merge pull request #159 from jix/fix-dpmem-example 
examples: Fix use of SVA value change expressions
 2022-05-11 11:23:57 +02:00
Jannis Harder fedfae0e9c examples: Fix use of SVA value change expressions 
The $stable value change expression cannot be true for a non-x signal in
the initial state. This is now correctly handled by the verific import,
so the dpmem example needs to start assuming `$stable` only after
leaving the initial state.

Refactor tests
 2022-04-25 11:21:21 +02:00
Jannis Harder 8da6f07cb3 Refactor tests 
Organize tests into subdirectories and use a new makefile that scans
.sby files and allows selecting tests by mode, engine, solver and/or
subdirectory. Automatically skips tests that use engines/solvers that
are not found in the PATH.

See `cd tests; make help` for a description of supported make targets.
