How to short two nets in a schematic

It is sometimes desirable or necessary to short two nets in a circuit using Virtuoso Schematic Editor. The traditional solution is to name the net at the top-most hierarchical level schematic so that only one net is created and named. A more flexible solution is to use the Cadence symbol cds_thru from the basic library to create a short between the two nets.

Note, the NCSU Design Toolkit replaces the basic library from Cadence with its own which may not have the cds_thru cell. To add this library (renaming it to basic_cds) to your CDS project, add the following line to the cds.lib file:

DEFINE basic_cds $IC/tools/dfII/etc/cdslib/basic
