gEDA-user: File Symbol Creation for an LQFP EP

["research@xxxxxxxxxxxxxx" <research@xxxxxxxxxxxxxx>]

Hello,

I am rolling my own symbols for my components. Namely an analog devices
sharc ADSP-21369 and altera FPGA. The footprint attribute for the chip
is LQFP208 1102. However, the chip has an exposed pad in the bottom.
According to the list

http://www.geda.seul.org/wiki/geda:scg#footprint_naming_conventions

There is no LQFPn x EP. How do I proceed?



Merci!

Omer Osman
