Find component and find net SKILL programs

EvanShultz

Hi all,

I was unsatisfied with the Find_Component.il program on SourceLink. It didn't quite have the features that I wanted. Plus, the zooming was broken (in 16.2 anyway). So, I modified the file. It's not revolutionary, but it's a nice enhancement. I added the ability to open the Show Element window after clicking on a part and zooming to the part is now done by a button, instead of automatically.

Then I thought, why not do the same for nets? So, I modified the component program to work with nets, with the same additional features.

 

I believe both programs are working fine without any issues, but please let me know if you find any problems so I can correct them. I appreciate any feedback  you may have. This was my first foray into SKILL so I hope it's helpful for everyone.

I apparently can only have one attached per post so Find_Net.il wil go on the next post. I made them TXT files for posting reasons, change them to IL files for use (obvious, I know).

 

Now, wouldn't it be great to have this same functionality in DEHDL instead of the silly Global Find window? Of course you'd need instance numbers since the ref des isn't there by default, but I think it could be done.

  • Now if that list were sorted "correctly" (i.e. J2 comes before J10 and after J1) -- you'd get an A+

    Kudos anyway -- nice updates!

  • Evan,

    Use CalStrNatCmp.il to get a natural order of your list. You can find it on this thread.

  •  Hi Craig,

     Wonderful! Thank you very much! calStrNatCmp.il works like a charm for the component list.

    However, for net list I have an issue: calStrNatCmp.il doesn't pay attention to the first character in the string if it's not a letter or number. This means symbols (!, @, #, $, %, etc.) aren't sorted, which is confusing since "+" and "-" are often used in net names.

     For example, I have "+15V_A" and "-15V" nets in my design. Using calStrNatCmp.il "-15V" comes before "+15V_A"  even though normal convention, and using sort() with u_comparefn = nil, would put all the "+" nets before the "-" nets.

    I don't want to take away your glory in case you want to change your code yourself, plus I don't have time right now, but I'll take a look at calStrNatCmp.il in a few days and see what could be done about this. Unless you get there first.

     

    For anyone who has tried the net program, do you find the "net list area" too narrow? Would it be better to make that wider? I found there to be enough room for named nets, and I wasn't concerned with the long, arbitrary names from packager requiring scrolling, but it's certainly easy to make the list wider. What do you think?

  •  Evan,

     Glad it helps.

     If I replace strs1 in CAL_strnatcmpTest with list("AA10" "A1" "A2" "A10" "AA2" "AW12" "B3" "B20" "+15V" "-15V" "!NOT" "*UP") the programs works fine. I get a sorted list of:

    !NOT
    *UP
    +15V
    -15V
    A1
    A2
    A10
    AA2
    AA10
    AW12
    B3
    B20

    The only character the algroithm ignores is *spaces*. Other than that it just seperates the charter strings and the numerical strings and then compares the substrings.

    Not sure why you are having a problems, but I'd be happy to help fix it when you have time.

     Craig
