assign a net to pins

masamasa

hello

i am using "net logic" to assign a net to a pin.

Is there any way to assign a net to a multiple pins?

I can assign only one pin at a time while i am able to assign a multiple vias at one time.

    Why do this in Allegro? You should drive the connectivity from the schematic. You'll need to make this modification at the schematic level, so drive this from the schematic. Don't make it hard on yourself.

    thank you for your reply.

    actually i am using ic packaging (apd) so i do not use a schematic.

    i just want to assign a net to pins manually.

    i do know that i can modify the netlist and import it but it would take time to find which pins has the same net.

    We deal with package houses building substrates for us, and have helped design the mcm files with them.  What we have done in the past was to build up the pin to pad nest in excel and sent it to them.  I don't know how they do the import, it my be by hand.  I have only worked on relatively small packages less the 100 pins and pads.

    thank you for your reply.

    the symbol i have has more than 57,000 pins so it is very difficult to do by manual.

    but it seems no other choice.

    thank you for your reply.

    unfortunately, it does not help.

    i would have to do it manually, i guess.

    thank you anyway.
