Hi again
Let me expand a bit further on this. Given any file that has a number of .SUBCKT calls I am looking to do a search and replace on the *.pininfo line. This line may extend multiple lines which are denoted by the presence of a + at the start of a line.

.SUBCKT foo a b c
*.pininfo vdd:I vss:I a:I b:I c:I vddw:I vddq:O
+ vddy:I

Now, I want to first get the complete *.pininfo line and then do a replace on certain words. Those words are of two types:

Powers which is a comma separated list held by the $runset{"POWER-NODE"}. This comma separated list first needs to to be split up, and at the end of each word get :P concatonated to it

$runset{"POWER-NODE"}="vdd,vddq,vcc"
# translates to vdd:P vddq:P vcc:P
[download]

Ground which is also a comma separated list held by the $runset{"GROUND-NODE"}. This comma separated also need to be split and concatonated with :G

$runset{"GROUND-NODE"}="vss,vsc"
# translates to vss:G vsc:G
[download]

Now using the *.pininfo line look for the variables held by both $runset{"POWER-NODE"} and $runset{"GROUND-NODE"} and do a search and replace. The tricky part is dealing with the :P/G/I/O. Effectively, we are ingnoring it during the search but replacing it after the fact. So, given the above example you would end up with a new *.pininfo which looks like..

.SUBCKT foo a b c
*.pininfo vdd:P vss:G a:I b:I c:I vddw:I vddq:P
+ vddy:I
[download]

Does this help?? Thanks so much
