@Tim Edwards, I have doubt in LVS lab exercise 3(LVS with black boxes). I have installed tools in my local pc. I tried to run same lab3 of lVS in local and vsd server . My local has sky130B and sever has sky130A. Both shows some different results for lab3. I am able to see disconnected node A, B,C in server but in local pc it not showing any info regarding disconnected nodes in comp.out file. Is it due ot some difference in sky130A and sky130B and what it can be?
