decrypt of skill

[Jan Mikkelsen]

Hi

I have a PCell skill file from a foundry and loading this goes nicely. The
only problem is that the file is a piece of crap and as such it is full of
errors. I want to make corrections to the file and have tried to decrypt it
using the decrypt.il file. I know that the file works as I can encrypt and
decrypt my own skill code and that still works. But when I try to decrypt
the foundry code I get errors when trying to load the decrypted file .. The
decrypted file starts of by

((NWELL = 3)) ..

I realise that this is not a correct start line .. but what went wrong is
what I wonder .. because the file looks nice and all ??

Well, it depends how you decrypted it (and I'm not going to go into that here,
and I'd prefer it if you didn't) - but it might be something to do with how you
did that, or it may be wrong in the original code.

Having multiple sets of matched parentheses in SKILL code is going to cause
trouble - it confuses the parser (mainly because of the flexible way it handles
C-like and LISP syntaxes). If the line was:

(NWELL=3)

or

NWELL=3

all would be OK, but with two sets of parentheses it will get confused.

Hi Andrew

I came to that conclusion my self also .. but thanks.
And dont worry .. I'll leave it at this.

Jan,

once fixed, it looks like this for me:

(pprint (car line) out) (fprintf out "\n" )
