modifying pin names of a symbol

kawan
kawan over 12 years ago

I need to grab a symbol, find all the pins and then change the names to include dig_ in front of the original pin names.

I then need to recrerate the symbol. I want teh symbol to have the same shape and pin locations as the original.

 So I have the following:

 ;test code

procedure( buildmysymbol()

pinlist = schSymbolToPinList("zakir_ams" "spi_top" "symbol")
pat=pcreCompile("dig_")
pinlist = pcreReplace(pat pinlist "dig1" 0)

schPinListTosymbol("zakir" "spi_top" "symbol" pinlist)
)

 

The cod edoes not work since the pinlist used in  pcreReplace(pat pinlist "dig1" 0) is  a list and not a string.

Any way to get around this?

 Thanks

      Andrew,

    What I really wanted to do was a little more complex substituition. But when it did not work, I played with a  simpler substitution which was the example I posted.

    if the pin name has "dig_", I need to remove it.

    if the pin name has "_1v1", I need to remove it.

    so  dig_tx_vcm_1v1_ch1<4:0> will become tx_vcm_ch1<4:0>

    In perl I would do:

      if (/^dig_(.*)_1v1(.*)/)
     {
     $newname = $1.$2;
     print "$newname \n";
     }

    I do not quite understand the pcreCompile & pcreReplace functions. Are there examples of this within the cadence documentations? If you can help with modifying the code you sent, I would appreciate it.

    Or if there is a way for me to use skill to read the pin information into a file ... then I can use perl to modify the file as necessary and then use another skill script to read the modified file and regenerate the symbol. I would be comore comfortable with this but if the skill can do this just as well, I would rather learn with skill. When I just type in the icfb window, the pin list is spewed out. 

    pinlist = schSymbolToPinList("zakir_ams" "spi_top" "symbol")

    How do I pipe this out to a file. My attempts below did not work

     schSymbolToPinList("zakir_ams" "spi_top" "symbol") > ~/spi_pins

     

    thanks
