parallel scan simulation failure

[lusian07]

I am encountering failures in parallel simulation. I am using the TSMC STD library and conducting post-simulation with the VCS tool. The root cause appears to be abnormal behavior in the standard cells. STD cells like BUF and AO are not functioning according to their truth tables. The same issue occurs even without applying SDF.

I don’t think there are any special simulation options being used. What could be the problem?

vcs -R -l vcs.log -f ./top.dft.f -j 8 -full64 +v2k -debug_access+all \
-o simv -sverilog -realport -wreal res_sum \
-lca -kdb -reportstats -top $top_nmae \
+fsdb+delta +define+no_wrning

Can you check if all memory models are hacked properly for parallel lib list? It is strange to see why std cell would behave differently!
