pcell means parameterized cell. It can be written in SKILL languge and executing it from CIW window. Or set design environment in Pcell mode and drawing it as layout. And giving the expressions to the corresoponding design. Usually, each device type has a corresponding Pcell layout. So you don't have to draw the tarnsistor layout from scratch. Just specify the size of the transistor and pcell will automatically create it for you. Usually use in Cadence VXL. For manu, go to your install path and doc directory to find the SKILL help menu.
