ASIC design flow:
Stands for Application specific integrated circuit.

This kind of design flow has been completely automated
with few manual steps

Below is the flow

1 ] system level specification
2 ]RTL coding and simulation

2 ] netlist synthesis , dft scan insertion ---> DFT ATPG,
STA,GLS can be run in this stage

3 ] physical design process
netlist extraction with actual parasitics
sign off STA , GLS , Power analysis will be done here

In ASIC , We use standard cells which are predesigned and
pre verified cells created as library from where physical
design tools will choose the correct cell to place and route.

Comapre and contrast this with Custom IC design where we do
not have so much automation , and also we do not use
standard cells instead custom cells are created for use in
custom IC design
