Success Story

Celestial AI Adopts Cadence Quantus Insight Solution for Intelligent RC Debugging, Optimization, and Signoff Closure in Virtuoso Studio Environment

The explosive growth in AI model size is driving the need for a step-function increase in memory bandwidth and capacity at low latencies. Celestial AI has been collaborating with some of the largest hyperscalers to develop a deep understanding of compute, memory, and network system infrastructure chokepoints. The Photonic Fabric™ is the only industry solution with the ability to shatter the “Memory Wall” and deliver data directly to the point of compute while supporting current HBM3E and next-generation HBM4 bandwidth and latency requirements at very low single-digit pJ/bit power.

 

The implementation of the Cadence Quantus Insight Solution has transformed our design process, allowing us to quickly identify and resolve parasitic-related design challenges. This advanced tool's capabilities in early prevention, rapid root cause analysis, and comprehensive diagnostics have significantly reduced our design closure time by up to 5X. Consequently, we have accelerated our time to market and now deliver high-quality solutions to our customers at an unprecedented pace.

Challenges
  • Analyzing 100GB+ DSPF ASCII files for RC analysis is excessively tedious and time-consuming, delaying tapeout turnaround
  • Significant delays in identifying and resolving parasitic root causes in custom/analog designs
  • Early design-phase bottlenecks and vulnerabilities lead to multiple ECO iterations, delaying signoff closure
Benefits
  • Reduced parasitic debugging time from four weeks to one week
  • Quick loading of 20GB+ DSPF files within minutes
  • Enabled designers to rapidly debug and optimize parasitics by identifying critical RC issues within minutes
  • Comprehensive analysis suite, including full RC analysis, RC delay, and DSPF comparison, helps pinpoint design issues for quicker resolution
  • Advanced, intuitive RC visualization in Cadence Virtuoso Studio and an interactive, user-friendly GUI streamline the post-layout simulation process
Design
  • High-performance Photonic Fabric™ Connectivity System in Package for AI
  • TSMC N5 20GB+ DSPF file
