G H TECHNOLOGY ELECTRONIC COMPONENTS

VLSI may have fallen short when it came to developing the first custom chip for Macintosh, but they are synonymous with semi-custom integrated circuits. Founded in 1979, VLSI built its first fab in San Jose, CA and ultimately built a second fab in San Antonio, Texas, after going public in 1983. A leader in gate arrays with their LSI logic, VLSI's cell-based offering opened the technology to smaller integrated companies in the semiconductor industry. Eventually, the company expanded to offer cell-based routing (chip compiler), datapath compilers, SRAM and ROM compilers and a state machine compiler. VLSI's design was manufactured as a solution for IC design. With VLSI components, a designer can edit transistor-level polygons or logic schematics, run DRC and LVS, extract parasitics from the layout, and run Spice simulation to back-annotate the timing or gate size changes into the logic schematic database. While VLSI was acquired in 1999 by Philips, they manufacture today as part of NXP Semiconductors.
