This paper provides a comprehensive guide to managing and mitigating congestion and shorts in VLSI design. By leveraging the practical approaches and ICC2 commands outlined, designers can enhance the efficiency and reliability of their designs, particularly in the face of increasing complexity and density in modern ICs.

Synopsys IC Compiler™ II is the industry leading place and route solution that delivers best-in-class quality-of-results (QoR) for next generation designs across all market verticals and process technologies, while enabling unprecedented productivity.

The objective of this paper is to illustrate congestion, shorts, and practical approaches to fix both issues at lower/higher technology nodes. This paper also includes PnR tool (ICC2) related commands and their uses to overcome the mentioned issues.
