===== 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! 


===== Open Virtuoso Layout XL from schematic =====
