IMPORTANT: The RAM, PROM, or PLA device definition contains structure information that
cannot be edited after the device is created. Adding or deleting any pins using the
device symbol editor will invalidate the device definition and render it useless.
The device symbol editor can be used to make the following changes to a
RAM, PROM, or PLA device, if desired:
 Any graphical changes to the symbol.
 Pin name, visible pin number, or pin attribute changes (including pin
delay and inversion).
 Limited pin type changes (e.g., changing to open collector).
 Part-attribute changes.
