During the last weeks I had an error when using abc pdr with SymbiYosys with various designs. When there is an SVA assertion which should fail, SymbiYosys itself fails with an internal assertion which results in a Python exception. If I correct the SVA, which fails, then SymbiYosys runs correctly.

If I correct the SVA, which fails, then SymbiYosys runs correctly.I've created a simplified test design which you can find here: https://git.goodcleanfun.de/tmeissner/bug_reports/src/branch/master/SymbiYosys_27
Running it with make results in an error like this:
The same error occurs when doing a bounded model check with
abc bmc3
. Thesmtbmc
engine is not effected.
