Introduction
Overview
The vcomp compiler is a full Verilog® language compiler. It meets most
of the IEEE Verilog® 1 spec including PLI 1.0 (tf_* and acc_* routines).
Currently the main missing parts are CLI support and lack of semantic support
of specify blocks (you can read them but they have no effect).
History
This compiler is a second generation compiler - it's predecessor was written
in the late 80s and directly produced machine code to run in a Macintosh
environment - it was used for private design work and for a period, until VCS® was
released, we believe it produced the fastest Verilog® simulations of its
day.
The current compiler is a complete rewrite from scratch - it is targeted at
an SMP implementation on the cheapest x86 boxes around - it uses modern
compiler optimization techniques including low level instruction scheduling
targeted at today's high end Pentium® class CPUs.
