vrename help

Hi,

Thanks for the nice tool. I would like to use vrename to automatically crypt all the signals except ports of a verilog file. It seems like there may be a way to do this by redefining use_cb_ports to something other than the use_vars. But I'm having a hard time figuring out the proper perl syntax and location to implement this.

Any help appreciated.

Thanks, Jon

vrename just does text based replacements. However you can write a script to read the I/Os of the top module (see man Verilog::netlist), and then just have that script print out

sigren "{sig}" "{sig}"

then concat that file onto the crypted signals.vrename file, and feed it into vrename for the final pass. (Thus this will override the crypted suggestions for those signals.)
