  • Re: Creating metal/vias stack layout and convert it into .gds file
    Hi Varun, I obviously haven't seen the format of the file you want to read thevalues from, but I very much doubt that involving Perl is necessary:modern SKILL has fairly powerful regular expressions (cf. Andrew'snumerous posts about the pcre* family of functions,e.g. http://www.cadence.com/Community/forums/p/14771/25538.aspx#25538). I ...

  • Re: Nested foreach loop
    Tjaart, Andrew, I couldn't resist coming up with a non-macro version for completeness (also at http://s.crosstwine.com/spb/8cda9957). I usually implement iteration constructs via higher-order functions, and sugar-coat them in a thin layer of macrology where/when it really improves readability. This one is a bit nasty because a function ...

  • Re: PB in foreach
    Hi Yann00, Not sure what you're trying to achieve exactly, but the first `printf` might be the culprit. In SKILL/SKILL++, printf("foo") is interpreted as: (printf "foo") whereas (notice the extra space): printf ("foo") is interpreted as, well, an error. (Technically, a reference to ...

  • Re: Link C++ - SKILL
    So it seems attachments to email replies get eaten by the system. Trying again, using the web interface; I have also uploaded an unpacked version to: http://crosstwine.com/misc/letters/2013/01/16/SKILL-C++-Interaction/c-delegate/

  • Re: Link C++ - SKILL
    Hi Yann00, As fxffxf wrote, system("program arg1 arg2...") should to work. One thing which *might* be going wrong is that if you are working under Windows, reverse solidus (\) characters have to be doubled in literal strings, as they clash with the SKILL escape mechanism: system("e:\\work\\program.exe arg1 ...

  • Re: pCell skill for beginners
    Hello Satishbabub, One thing I noticed is that you commented the pcDefinePCell form to replace it with a (define (jfet... ) ...) procedure. That is not a bad idea, but is not sufficient; pcDefinePCell has "special" evaluation semantics. In the code you posted, (list (ddGetObj ...)) won't cause pcCellView to be bound in the body. ...

  • Re: How to parse the contents of a file?
    Hi Sanramz, What Andrew said. You are also missing a level of parens in the let( (cv) ... ) of create_boundary. As I was reindenting your code to get a better view, I couldn't help but split it into a couple of procedures as suggested by Andrew; the following seems to work for me: ;; File format: ;; ;; cell_name llx ...

  • Re: Slotted Metal paths - updated form for v5.1.41
    Hi Jaleco, The short answer is that you cannot use the == or != operators to compare floating point numbers. Try something like: abs(a - b) instead. The next problem, of course, lies in determining a good value for ε in your application; thick books have been written about that subject. Using something smaller than 1/DBUPerUU should do ...
