FirstPass Engineering

Our mission is to enable our strategic clients the power to create cutting-edge products that raise the standard for the way the world lives using our world-class program management and IC design, paired with our unblemished track record for success

FirstPass was incorporated in 1993 with the goal of providing ASIC design services to the Mil/Aero marketplace. Our expertise soon expanded into commercial space and commercial devices.

From 2000 to 2005, FirstPass was a captive design house for Vitesse Semiconductor Corp., focusing on development of complex ASICs for the telecom market including Intelligent Switch Fabrics, PCI and SATA type devices. We drove methodology improvements company-wide, especially in verification.

In 2005, FirstPass reincorporated as an independent design services company. We have enjoyed solid growth and re-established ourselves as an outstanding provider of ASIC and FPGA design services.

FirstPass has remained ahead of the technology curve, maintaining our high level of expertise through the technical changes and advances in pre-silicon verification, tools and methodologies.
