@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?

The exercise contains no sky130 devices, so the sky130 setup should have no effect on it.

yes no sky130 device in both spice file, but getting different outcomes

Your netgen versions are different.

1.5.227

vs

1.5.196

@Deepak: There are some minor differences in the output text messages and formatting that were merged into recent versions of netgen (by Mitch, above). If you are getting the same ultimate pass/fail result, then it's okay; you're just seeing some formatting changes because netgen has been modified a bit since the lab material was created.

okay Thansk @Mitch Bailey , @Tim Edwards
