What is Physical Design?

The process of converting a gate-level netlist (written using your Hardware Description Language(HDL)) into GDSII (Geometric Datastream) or physically realizable format(having geometric shapes) which finally becomes a hardware is called Physical Design.

Structural representation to physical implementation (ie.,) Netlist to GDS.

Consists of 2 stages:

Placement & Routing (P&R)

Signoff

Objectives:

Timing

Congestion

Area

Power

Possible issues seen:

Timing violation

Congestion Issues

Design rule violations

I have a strong passion towards VLSI-CMOS, Physical Design(Both Placement & Route /Signoff Analysis),Digital Design etc. If you like my posts, kindly share it with people interested in these topics. It really mean so much to me. Hope you find something useful in my blog .
