Inverter layout tutorial

Introduction

Schematic entry

The first step always consist of creating the schematic of the circuit that we want to simulate. Create an inverter consisting of a PMOS an NMOS. Make sure that you also include input/output and VDD/GND pins as we will need those to do Layout Versus Schematic (LVS).

Importante! Posso aprire con Layout Editor XL che cosi' mi permette

1) mi apre anche lo schematico insieme

2) posso generare i transistors direttamente dallo schematico!
