Ansys ParagonX
IC Layout Parasitics Analysis and Debugging Software

Many thousands of layout parasitics dominate integrated circuit (IC) performance. ParagonX provides early, fast, and easy parasitic analysis with visual debugging and root-cause detection.

Intelligent Analysis, Visualization, and Debugging Tool for IC Layout Parasitics

ParagonX lets IC design engineers shift left to quickly explore and find the root causes of parasitic-induced design issues. It enhances existing EDA workflows with powerful analytics and visual feedback for identifying the root causes of layout parasitics’ impact on performance, precision, robustness, and reliability earlier in the design cycle.

Quick Specs

ParagonX is a process-agnostic tool that identifies parasitic-related design issues at an early layout stage, even before the design is LVS clean. Understanding the impact of layout parasitics is critical, especially for designs manufactured with advanced process nodes. This avoids productivity delays from performance bottlenecks and weak points later in the design process. With its unrivaled speed and capacity to handle huge netlists, IC layout engineers can find root causes and fix parasitic issues, leading to enhanced design quality and shorter design cycles.

  • Unrivalled speed and capacity
  • Easy visualization features
  • Powerful root-cause debugging
  • Python extensible
  • Automated net and device matching analysis
  • Automated ERC verification
  • Process agnostic

  • Python extensibility

Ansys ParagonX can easily handle large netlists, and provide debugging results as quickly as minutes or hours.

Ansys ParagonX is the only solution that not only finds the parasitics issues but also the root cause of the problem.

This makes parasitic debugging and layout optimization easy and efficient.

ParagonX offers easy integration with popular custom layout tools.

The analysis includes coupling capacitances, point to point resistance, RC delays, instance matching, 2 or N nets.

It can detect potential circuit errors early in the chip design process and ensures the functionality, reliability, and performance of ICs.

Ansys ParagonX is Python extensible so that you can create your own workflows to address your unique engineering challenges.
