Physical Design & Signoff

Helping businesses achieve the best PPA goals in the least turnaround time

InSemi specializes in Physical Design services from RTL to GDSII leveraging Cadence & Synopsys EDA Flows. 

Our strength lies in working on lower technology nodes like 3nm, 5nm, etc. The subject matter experts at InSemi are well versed with physical design flow and methodologies, ensuring projects achieve optimum power, performance, and area (PPA) goals.

The core objective of our team is to ensure customers with faster time to market by creating designs that swiftly skim through foundry-specific DRCs, LVS, and ERCs, avoiding multiple iterations.
