Module Generators (Modgens)
Virtuoso® Module Generators (Modgens) provide a way generate multiple Pcell instances into a complex, highly matched, structured array. You can use the Modgen tool to specify the devices to be arrayed, specify an interdigitation pattern, and insert dummy devices, body contacts, and guard rings. You can also control the routing style and generate internal routing geometry.
Modgens can be created from either the schematic or the layout cellview. When you create a Modgen from schematic, the tool creates a Modgen constraint on the schematic, which can then be generated in the layout using the Generate All From Source or Generate Selected From Source commands.
When run from schematic, by default, a Modgen creates a temporary physConfig. You can use the modgenPhysConfigs environment variable to specify a different physconfig for the Modgen.
