Universal "Comment" Character

Is there a universal character in ALL variations of "Spice" netlists that designates that the following text is a comment only?

(Trying to adjust my LVS templates so that ALL layout editors will recognize comments.)

So far it looks like ONLY a newline beginning "*" works for ALL cases :-(

All of the model files I have collected use the '*' cahracter.

That (*) only applies at the beginning of a _new_line_.

Looks like both PSpice and HSpice use ";" for comments _in-line_.

But my real need is talking to chip layout tools...

Tanner Tools

etc.

Not yet. But I'm thinking about starting a second life writing engineering tools ;-)

Don't you have a son who is a programmer? A text pre-processor that substitutes one code for the others would be pretty easy. It could have an option to choose the code for the output file.

Maybe something could easily be thrown together in Perl (or even simple-Simon awk).

Yes, here's a Perl script that does just that. Enjoy! It does semicolon and double-slash comments, but you should be able to see how to extend it.

--- cut here --- #!/usr/bin/perl -p # Takes end-of-line comments in SPICE files and puts them in before the lines # in which they appeared as regular SPICE asterisk comments. # Usage: # # perl -p spicecomments.pl originalfile > newfile # # or (to do an in-place edit): # # perl -pi spicecomments.pl originalfile

# semicolon end-of-line comments s#^([^;]+)\\s*;(.*)#*$2\\n$1#; s#^\\s*;(.*)#*$1#; # double-slash end-of-line comments s#^(.+)\\s*//(.*)#*$2\\n$1#; s#^\\s*//(.*)#*$1#;

You can use SED to alter text strings in an ASCII file. Incorporate SED into a batch file to make life easier. It will take a file, process, then write it out to another file leaving the original alone. SED can use reg ex for those really sticky issues. SED can be daunting, but you will quickly appreciate what it can do.

On thinking about it a bit the only relatively reliable one is likely to be Asterisk in column 1, required for backward compatibility from the old Fortran days.

That's my suspicion also. Since my netlister can insert a newline that's what I'll probably settle on.

Sometimes, you can use cpp for hacks like this. It often works very well if you are using make.

(cpp is the c preprocessor that processes things like #define and #if.)

sed probably can be made to do it all.

Any sed masochists out there?
