Hi,

I've been trying to do a layout on the NCSU Design kit provided technology (AMI0.6u).

I am testing a layout on a simple inverter. Everything works great initially, I was able to do DRC, Extracted, and LVS and pass. However, it suddenly won't work today once I want to do a LVS again without me doing any modification. The error message I am getting is attached. Have anyone face similar issue before or know the solution? I've been stuck for 2 days...
