modifying pin names of a symbol

kawan

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

zakir

    Hi Zakir,

    A quick no-coding approach to this would be to use Create -> Cellview -> From Cellview to create the new schematic from the existing symbol - this will get you all of the pins and their appropriate directions in an otherwise blank cellview.  Then you can place the original symbol in this new schematic and use the option to create wire stubs for all of the pins; this option creates a wire stub on each pin with the name of the pin as a label on the wire - these wires will be logically connected to the schematic pins of the same name, so no additional wiring should be needed.[I'm assuming that you are using at least IC615]

    It sounds like you aren't too concerned about the appearance of this schematic, so hopefully this suggestion will meet your needs?

    Best regards,

    Lawrence.
