That pretty well rules out downloading -- better ask someone to snail mail a
CDROM. Hmm, maybe a DVD=ROM.

At Bell Labs in 1998 we had guys who had been good ASIC designers, serious
hardware engineers, who were now doing ASIC design completely in VHDL. Every
day they acted more like software programmers, and got treated like them by
management too.
VHDL, BTW, is probably the worst programming language that's less than 15
years old. It combines the worst features of ADA and ALGOL, plus some semantic
tricks of its own, like global variables that don't change value everywhere
when you assign a new value to them.
I was glad to keep on doing circuit board design (with their chips) and
writing genuine software for lab testing.
Oh yes, we had a couple of Xilinx parts and programmers to work on them.
SOmeone was right -- when you finally integrate all the subsystems on the final
chip, all kinds of extra gates and speed losses show up due to overhead. So
do budget for that.
