I don't want a windowed environment or a waveform viewer, I want to do all my development from an ASR33! That's why I love Icarus Verilog, it is 100% command line. Although unfortunately it wants "modern UNIX" and won't build under 4.3BSD (written in C++ for a start), since it's command line I can have it running on my Linux box and use it from my main development VAX via rsh. OK, that's good to know. Because I want to, for religious reasons. I don't want a good tool, I want a free one (free as in speech). Freedom is more important than quality to me. I'll gladly settle for a design that requires a 10 times larger FPGA than necessary and has a 10 times lower maximum clock speed if it can be done with free-as-in-speech tools. Thanks, MS, religious zealot, evangelist of Free Software and command line environment.
