If I move a group of pins down by one in the schematic the connectivity is moved down by one and all the pins are misconnected. Is there a way to have cadence maintain the connectivity so this doesn't happen?... more »

Is there anyway to generate schematics using OCEAN netlists? 
  Hello, what I have are some netlists used in OCEAN. But now I need to draw the layout of the netlists in Virtuoso, so I have to make the schematics first. Capturing schematics totally by hand is a pain...So I'm wondering if there's anyway to generate schematics in Virtuoso using netlists of OCEAN?... more »

Porting schematic with one grid/snap spacing to another 
  Hi all, I am trying to port schematic with one grid/snap spacing to another environment that has a different default spacing. How can I accomplish this without having to resort to redrawing the schematic to interface with the other cells that were drawn already? Thanks. Robin
