Joe,
Thanx for the file. I will look at it soon. The company I?m working for
allocated a software guru to create a ?quick and dirty? skill file which
used the existing XL spreadsheet values and I was able to import all of the
pins I need. I think your file, from what you describe, will be very useful
for other future needs though and I really appreciate your response.
Thanks again.

Jim,
I've got an excel file that runs a VB script to generate an Allegro Script
for doing just what you need. Drop the data in the fields and hit the
Create Script button.
Nothing fancy and NOT supported but works great for me.
Zip file attached.
Thanks,
Joe

Jim:
I have not heard of anything like that "canned" and ready to run.
It does not sound like a major task to write one if somebody had the time to
do it. It most likely would need a .csv from the spreadsheet to provide the
data.

Hey folks,
Using Allegro version 15.5.1
I?m hoping that someone knows of a skill file available that can place pins
for a very complicated ceramic/BGA configuration (5000 plus pins).
The pins have varied numbers, including the typical A1 through AZ##, and E1
through EZ##. What I?m working with here is two BGA?s within the same
package. Silicone on silicone. The pin positioning is also varied. The outer
BGA pin array is a standard pattern, but the inner BGA pins are not.
I have an XL spread sheet that lists all of the pin numbers and their X & Y
coordinates.
Is there a skill file that anyone knows of that can insert the pin number
and place the pins, sourcing an XL spreadsheet or even a simple text file,
in their required locations?
Keep in mind the spreadsheet is very easily manipulated to accommodate the
skill file. Meaning, I can put all of the pin numbers & coordinate
information in one cell, or divide between 3 or more cells.
Without some kind of automated method, I fear for the accuracy of the
symbol. (not to mention the mind-numbing process of verification)
Thank you in advance. Any input would be appreciated.
