In my recent studies of electronics (I'm a noob for all practical
purposes) I keep seeing folks refer to Verilog almost as a verb. I read
about it in Wikipedia and it sounds pretty interesting. It's basically
described as a coding scheme for electronics, similar to programming but
with extras like signal strength and propagation included. Hey, cool!
Why are folks referring to "Verilogging" and "doing a verilog" on
older
chips. Is there some way you can stuff an IC into a socket or alligator
clip a bunch of tiny leads onto it and then "map" it somehow into Verilog?
Is that what folks who write emulators do?
They firstly go by documentation, and if that fails, reverse engineer,
painfully. This is why preserving, archiving, publishing documentation
is so incredibly important!
Ie.. they exhaustively dump
Verilog code for all the chips then figure out how to implement that in
You can't in general get Verilog *out* of a chip. It goes the other way.
You can compile Verilog into gates and netlists etc.
some computer programming language like C ? What do
folks do for ROM chips
and PLCs? I'd think they must dump the code and disassemble it. No?
Yes, they do that where possible.
I'm just curious and this is a tough question to answer with Google since
I'm pretty clueless and don't know the right words to search for. I notice
You can google "EDA tools". You can also grab toolchains from major
vendors like Altera and play with Verilog/VHDL and simulate the results,
too.
people talk about correcting their Verilog code, so it
must be somewhat of
a manual process. I'm just wondering how someone even gets started with a
process like that.
I'd suggest hitting some textbooks, not Google.
Niklaus Wirth's book is fantastic, for people more comfortable in
software, if you take it step by step:
