Automatic Routing for Cadence Analog Layout XL

[ke11y5]

I am using the automatic routing tool under 'Route' in Layout XL (IC6.1.6) and cannot figure out where the rules for spacing are located. I'm laying out a simple OpAmp with a current mirror and implementing the common centroid technique for a few of my mosfets. When running the routing tool everything routes correctly except the contacts. The contacts, CA, are placed on top of the active layer, RX, of my nmos and pmos's, which violates the spacing rules. I've searched through the edit functions under 'Sequence' and haven't found anytihng about spacing. Some help would be great. Thanks.

Formerly - in IC5 - these were in the technology file. Don't know if this was kept.

Yes I think you are right. And there is a rule in there for spacing. When running the auto routing I selected the default constraints, spacing rules included, but that one isn't followed. I've sort of found a solution by just placing contacts prior to running the auto route. Thanks for the help though.
