multi symbol device from a previously single symbol device

Hi All,

 

I'm struggling to split the symbol on a device I created, its a many pin

processor which i originally designed as a device with one package and

one symbol, I'd now like to split that symbol onto a few different

functional pages of my schematics (power, memory, IO devices, etc),

instead of having one massive symbol with all of the pins and no room to

actually draw the schamatic.

 

I'd like to split it into several sub symbols that I can place on

different sheets of my design that are more related to power, memory, io

devices, etc..

 

This is a 300 pin BGA package and i've spent a lot of time and effort

making sure that the pin to pad mapping is correct with my current mega

symbol, is there any way I can create additional symbols for the part

and cut pins from the mega symbol to the relevant function symbol while

still maintaining the mapping of pin to pad number ?

 

Any help appreciated.

First step is to divide the symbol into several new symbols with

GROUP, CUT and PASTE. Create a new device then and add the package.

Now RUn split-device-symbol.ulp. It compares the pin-pad connections

of the old device with the pin names of the symbols in the new device

and executes the CONNECT command then.

A description how the ULP works is in the ULP.

Excellent, that did exactly what I wanted, thank you so much...

I had a couple of false starts with not knowing exactly what the script

wanted but once I figured that out, it just did exactly what I wanted it

to do.

The software and the scripts in combination with this group make for an

excellent piece of software.. even more glad I spent the money now.
