Hi All,
I have had no problems with the DRC and LVS. But when I run PEX, the extraction starts and ends with the following error without producing any output netlist.

We have recently moved to v2012.2_17.11 version of Calibre.
Anyone has experienced this problem before?
Thanks,

Hi N-
What does your Mask SVDB Directory statement look like? The XDB information is only generated if you have certain options set. It is not generated by default by LVS.
Best-
Sam.
