UCSB SoC Design and Test Lab

Welcome to UCSB SoC design and test lab! This lab was founded by Professor Kwang-Ting (Tim) Cheng in 1993. We focus on developing methodologies, algorithms, techniques, and tools for validating, verifying, testing, and synthesizing deep sub-micron (DSM) system-on-chip (SoC) devices as well as flexible electronics.
