Analyzing Net Expression Property Names and Evaluated

Names

The Virtuoso® Schematic Composer now displays all evaluated net expressions in a design hierarchy. This enables you to verify that devices connect to the right nets at each level in the hierarchy.

The most helpful task in analyzing net expression property names and evaluated names is searching for net expressions and related names and properties. The Virtuoso schematic composer has various ways to search for a net expression. You can also find net expression and netSet overrides in the instance hierarchy and find the actual evaluated results, which can be the default signal when there is no netSet override.
