svinst's Issues

parameter with quotation marks "TRUE" "FALSE" in python

I just installed the svinst from pip install svinst and want to try it with a simple module like this:
a.sv

module t1 #(parameter P="TRUE")();
reg a=0;
b #(.P(P))b1(.a(a));
endmodule

I can use the command line and get the full tree with no error by.

svinst a.sv --full-tree

But if I do the same thing in python,

import svinst
svinst.get_syntax_tree('a.sv')

I got the error message

  in "<unicode string>", line 50, column 54:
     ...                      - Token: ""TRUE""

For me, it looks like it got confused by the quotation mark " in the string.
Maybe for the yaml it generate, the quotation mark should be escaped like "\"TRUE\""

or the full error message

Not include .vh friendly!

Hi,

I noticed those.SV files starting with `include "*.vh" are not supported. The tool shows an error message for these kinds of SV files.

Time out when get_defs.

Hi,

I'm trying svinst in my code, but it always time out when get_defs, see the pic below for detail. Any ideas what's wrong?
