From: dmcinnis@speedsim.com (Don McInnis)
John, regarding Digital's Proprietary technology: SpeedSim/3 is an entirely
new implementation of a cycle-based simulator. (It's called "/3" because
it's the third cycle-based simulator developed by the SpeedSim founders.)
We did legal due diligence before starting the company to insure that
SpeedSim did not violate any of Digital's intellectual property rights. By
comparison to DEC's internal Cycle simulator, SpeedSim/3: supports Verilog,
supports RTL constructs, uses a fraction of the memory, compiles & builds
almost 10X faster, and has run-time is about 3-5 X faster.
SpeedSim/3 is completely different simulator than Digital's.
