ULP: When iterating through parts, can I get to nets?

bbartley

I'm creating a ULP to export a netlist but for my purposes it would be a lot more direct to iterate through the parts, and export those one by one, specifying what net is on what pin. But the data structures visible via the ULP interface seem to only make it possible to see what parts are on a net (rather than what nets are attached to a part). Am I missing something, or am I going to have to build up a whole counterpart to the existing data structures to do what I need?

 

Thanks,

Brad

    Isn't this just a matter of sorting? From allnets(), loop through

    pinrefs and store the net.name and part.name in two string arrays. Then

    use sort().

    I was a bit quick. You may want to add the pin.name to that list so it

    ends up like: part.name,pin.name,net.name

    Ahh, the extended functionality of sort() is what I was missing. So I *do* have to build up a counterpart data structure (the parallel string arrays), but sort() makes it easy to flip that around from net-centric to part-centric.

     

    Thanks very much!
