Calibre LVS device recognition

Question asked by mike_pelham on Aug 9, 2009

I have a strange thing . Some devices in a netlist are being recognized as generic MOS rather than their correct type . I can't see any difference in the netlist between godd and bad devices.

Here is the relevant part of the report . You can see that the 'extra' M type devices correspond to the missing mn devices in the layout.

What should I look for ?
