What Infinisim does

Infinisim, Inc. is a privately held EDA (Electronic Design Automation) software vendor headquartered in San Jose, California, that builds SPICE-accurate clock verification tools for advanced-node system-on-chip (SoC) designs. The company sells a three-product suite — ClockEdge for end-to-end full-chip clock timing and electrical analysis, JitterEdge for power-supply-induced jitter (PSIJ) analytics at sub-picosecond resolution, and a Clock Aging Analysis module that models HCI and NBTI degradation. The technology traces clocks from Verilog gate-level descriptions through to transistor-level netlists, sensitizes clock paths through complex gates, and runs SPICE-accurate simulation across multiple PVT corners and Monte Carlo iterations at capacities of 4+ million gates per overnight run. The product is positioned as the signoff tool for sub-7nm high-performance clocks where static timing analysis is insufficient.

The company was co-founded by Samia Rashid (President) and Dr. Zakir Hussain Syed (CTO), with Dr. Perry Gee as VP of Engineering; all three are veterans of Simplex Solutions, which was acquired by Cadence in 2000. Infinisim targets leading-edge fabless semiconductor companies and foundries designing at 7nm and below, and goes to market via direct enterprise sales with one-time software licenses under multi-year contracts; pricing is not publicly disclosed and is handled through [email protected]. The company has 1–10 employees, has not disclosed any external funding rounds, and supports demand generation through technical content on SemiWiki, webinars, and gated whitepapers rather than a partner channel.

The business is best characterized as a profitable, founder-controlled niche EDA specialist operating in a structurally small but high-value advanced-node signoff market, with no disclosed M&A, capital raises, or geographic office expansion beyond the San Jose headquarters.

Core offering

Infinisim develops and licenses enterprise EDA software for SPICE-accurate full-chip clock verification of System-on-Chip (SoC) designs at advanced semiconductor process nodes (7nm and below). Its products perform timing, jitter, and aging analysis on clock domains containing millions of gates, providing signoff confidence for fabless semiconductor companies and foundries designing high-performance chips. Software is delivered as licensed downloads to enterprise customers under multi-year license agreements.

Product overview

Infinisim offers a suite of three integrated clock verification products for semiconductor SoC design: ClockEdge (primary sign-off solution for comprehensive timing and electrical analysis), JitterEdge (specialized power supply induced jitter analysis), and Aging Analysis (clock signal degradation prediction). Together, these products provide full-chip clock verification covering timing optimization, jitter computation, and aging simulation, enabling customers to achieve SPICE-accurate analysis at advanced process nodes (7nm and below) for sign-off confidence.

Direct peers

• Real Intent: Real Intent specialized in clock-domain crossing (CDC) and RTL signoff verification, directly competing with Infinisim's clock verification focus. The company was acquired by Cadence in 2022, validating Infinisim's niche but eliminating an independent rival.
• Atrenta: Atrenta was a direct competitor in SoC verification and early RTL signoff, including CDC and clock integrity analysis, before being acquired by Synopsys in 2015. It is a historically comparable peer whose acquisition illustrates the consolidation pressure on niche EDA players.
• Blue Pearl Software: Blue Pearl Software provides clock-domain crossing analysis, synthesis checking, and visualization tools for ASIC and FPGA designers. It serves a comparable audience of chip designers concerned with clock integrity and verification at advanced nodes.

Broad incumbents

• Synopsys: Synopsys is the largest EDA vendor and offers PrimeTime for static timing analysis and clock verification as part of its broader digital design platform. It competes with Infinisim in the clock verification/signoff space while serving a much wider portfolio of EDA customers.
• Siemens EDA: Siemens EDA (formerly Mentor Graphics) provides Calibre, Tessent, Questa, and Solido variation-aware design tools that serve similar advanced-node semiconductor customers. Its broad EDA portfolio overlaps with Infinisim's clock verification niche.
• Cadence Design Systems: Cadence is a leading EDA vendor offering Tempus timing signoff, Voltus power analysis, and other digital implementation/verification tools. It acquired Real Intent in 2022, expanding its clock-domain verification footprint that overlaps with Infinisim's offering.

Emerging players

• Agnisys: Agnisys provides EDA tools for register automation, SoC design, and IP verification, serving many of the same fabless and IP-provider customers as Infinisim. Its broader design-automation focus places it as an emerging overlap in the SoC verification ecosystem.
• Aldec: Aldec provides digital design simulation, hardware verification, and FPGA prototyping tools used by semiconductor and electronics customers. Its verification portfolio is adjacent to Infinisim's clock analysis focus.
• Breker Verification Systems: Breker provides system-level testbench synthesis and SoC verification tools used by semiconductor companies to validate complex designs. It addresses a different verification phase than Infinisim but serves an overlapping fabless customer base.
