🧠 Overview

Infinisim, also referred to as “Infinism,” is a specialized EDA company focused on full-chip SoC clock verification. Their suite offers highly accurate analysis tools for advanced semiconductor designs, helping detect timing, aging, jitter, and power-supply‑induced clock issues that traditional static timing analysis often overlooks.

The company positions itself as the leader in SoC clock verification technology, targeting high-performance designs where nanometer-scale effects significantly impact system reliability and yield.

🔧 Core Products & Technology

SoC Clock Analysis

• Verifies full-chip clock networks for timing consistency across advanced nodes.

• Detects structural and process-induced issues like skew, jitter, and aging effects not visible in standard STA flows. Infinum+5SemiWiki+5Bloomberg+5

Clock Jitter Analysis

• Accurately computes jitter introduced by power-supply variations or noise coupling across clock domains. Helps prevent subtle failures in high-speed clock operation.

Clock Aging Analysis

• Models transistor-level aging effects over operational lifetime, which can skew duty cycles and degrade timing margin over time.

• Addresses issues that often appear only after silicon deployment but are traceable with pre-silicon aging simulation.

• Uses advanced analysis techniques—beyond traditional STA—for faster and more robust results on designs at billion-transistor scale.

🏛 History & Leadership

• Dr. Zakir H. Syed is a co-founder and CTO with nearly 30 years of experience in EDA, previously at Simplex Solutions (acquired by Cadence in 2000). He has authored multiple technical papers and regularly participates in industry forums.

• The founding year and early funding details haven’t been publicly disclosed. Public insight into the company comes largely through SemiWiki interviews and limited online profiles.

🌍 Market Position & Use Cases

Infinisim focuses on high-performance chip designs where clock integrity and longevity are mission-critical. Their tools are particularly valuable for:

• Leading-edge process nodes (7 nm, 5 nm, below)

• High-frequency applications like AI accelerators, networking ASICs, and high-speed SoCs

• Designs where aging, jitter, and noise risks can significantly affect yield or performance

• Designs vulnerable to semiconductor aging or voltage supply variations that remain undetected by conventional flows

Their customer base appears to include advanced semiconductor firms and teams facing difficult clock-related design issues—teams often open to Infinisim’s technology once past failures motivate deeper analysis.
