In this tutorial you’ll build an inverter in two different ways: as a schematic and as layout. You know how to simulate the inverter using an Analog simulator. After you design and simulate the schematic, you will design layout for an inverter and simulate a circuit extracted directly from the layout. You will be able to compare the two simulations and see how they differ. You will also check the layout for design rules, and check that the layout matches the schematic. Layout consists of the mask designs for each layer that gets sent to the chip fabrication service.
Schematic:
Draw the Schematic of an Inverter in virtuoso Schematic Editor and make a symbol.
Transistor Sizes: (W/L)p = 3.0/0.6 and (W/L)n = 1.5/0.6 (All in microns).
Body of pMOS is connected to Vdd and that of the nMOS is connected to Vss.

Schematic test bench for the inverter:
Make a new schematic cell “inverter_test” to test the inverter you designed, as |
