The Following diagram shows a simplified view of a typical digital VLSI design flow by taking into accounts the various representations of design; behavioural, logic, circuit and mask layout. (a) At which design step(s) would your device models be necessary? (b) At which design step(s) would your HSPICE be useful? (c) at which design step(s) would your Magie program be useful? (d) At which design step(s) would the design rules be necessary?

Solution

a) Device models are required during circuit phase for circuit simulation.

b) HSPICE is a circuit simulation software, hence required during circuit phase.

c) Magic is used to create layouts of circuits, hence required at physical-layout level.

d) Design rules are need to be satisfied while creating layout, hence rules are required at layout level.
