Using perl to parse verilog

[wolfpack307]

Hi all,

I am trying to use perl to parse a verilog file.

In trying to parse block comments, I am using am doing

while ($verilog=~s/(.*)\/\*.*(.*)/$1$2/) {}

This code does work for code that looks like this

/* comments
comments
comments */

However, if an codes look like the following (which is syntactically
correct in verilog), the script just hangs.

/* comments
/* comments
comments */

Would appreciate some advice.
Thanks in advance.
