Answers to common Verilog questions are provided in this appendix.

Origins of Verilog HDL

Verilog HDL originated around 1983 at Gateway Design Automation, which was then located in Acton, Massachusetts. The language that most influenced Verilog HDL was HILO-2, which was developed at Brunel University in England under contract to produce a test generation system for the British Ministry of Defense. HILO-2 successfully combined the gate and register transfer levels of abstraction and supported verification simulation, timing analysis, fault simulation, and test generation.

Gateway Design Automation was privately held at that time and was headed by Dr. Prabhu Goel, the inventor of the PODEM test generation algorithm. Verilog ...
