I'm assuming you're on a unix system. This is something someone sent me
some time ago. The idea is to do some post processing in vi. I know its
not in Synopsys but may help you anyway if you play a bit.
1) Open your vhdl or verilog netlist in vi.
2) Place your cursor at the beginning of a paragraph.
3) Press the escape key.
4) Enter the command to run UNIX /usr/ucb/fmt (default 72 columns) on
a complete paragraph: !}fmt
5) Press the return key. This will format that paragraph to 72 columns,
wrapping intelligently. To format to different column widths, e.g.,
50 columns, use: !}fmt -w 50
To format the whole page, use the from-line-1-to-the-end syntax:
:1,$!fmt -w 78
Or, another way to format the whole page is to use the whole-page syntax:
:%!fmt -w 78
It's an idiots guide just in case you don't know vi. Hope this helps.
