Hi guys.
I'm using cadence virtuoso for the TSMC 28nm manufacture.

and there weren't problem until I finished DRC and LVS test. but when I tried PEX, I faced over 150 warnings and couldn't extract any resistance or capacitance,

these are my error pictures. and some of them are usual warnings I've had before( I didn't have any problem to PEX when I used 65nm manufacture).
