Verilog was created by Prabhu Goel, Phil Moorby, Chi-Lai Huang, and Douglas Warmke between late 1983 and early 1984.[3] Chi-Lai Huang had earlier worked on a hardware description LALSD, a language developed by Professor S.Y.H. Su, for his PhD work.[4] The rights holder for this process, at the time proprietary, was "Automated Integrated Design Systems" (later renamed to Gateway Design Automation in 1985).
