Pin swapping for a heterogenous part

rezrez
rezrez 5 months ago

Hello,

I have a micro controller with a lot of pin which the symbol is created in a few sections (heterogenous part). As I'm just using the IOs as GPIO, all the ports are more or less the same for me (there are only three groups: ADC, 5v IOs and 3.3v IOs).

I wanted to use pin swapping feature so I added 1 to 3 for the above groups. the problem is that it works separately in each section. Which means I can only swap group 1 with the ones which are in that section only. But I have group 1 in the other sections as well. How can I use pin swapping for whole the package and not only in each section?

Thanks

    Hi Rezrez

    The help file for capture has some good info on this. Do a search for "PINGROUP" within the help. Basically what you are after is the ability to do what used to be called a gate swap between sections of a symbol. Typically this can be useful for large pin connectors or BGA's etc.

    I am unsure what version of capture you are on but from my reading you would need to add some properties to the part such as SWAP_INFO and define the pins  so they are swappable as part of a group.

    Hopefully the help file will provide suitable clues for you.

    Best regards.
