I'm working on the design for an Omnibus (PDP-8/E) debug board and I am
not very good at circuit design. I know there are programs that will
compile something that looks like C into Verilog/VHDL/Abel/Etc for use
on some kind of large (more than 64 pins) programmable logic device.
There are still some 84pin chips out there(Altera & Xilinx). Sometimes
they are pulls, or some 5V tolerant xilinx xc95xxxxl
Can any of you recommend a good C like tool for programmable logic?
Stay away from them :)
At the end, you will spend as much time learning the differences
(as it is not real "C") so invest the time in learning system verilog or
VHDL. VHDL is a little more verbose, system verilog lets you shoot in
your foot much easier.
If you just like to "debug" the bus, get an FPGA & some level shifters,
very easy to do ...
