Problem Title:
Foundation Schematic:  How to control output slew rate


Problem Description:
Keywords: output slew rate fast slow
Urgency: Standard

General Description:  How can I set certain outputs to be
FAST or SLOW slew rate on a Foundation schematic?


Solution 1:

If left unspecified, all outputs will default to SLOW slew
rate.

To specify the slew rate to be FAST, do the following:

1. Double-click on the OPAD you wish to make FAST

2. In the "Parameters" section of the Symbol Properties
   Dialog box, find the box labeled 'Name:'.  Type FAST in
   this box.

   The FAST attribute only requires a Name, and does not
   require a Description.

3. You will now see FAST= in the box which lists all the
   parameters.	The number of dots next to the attribute
   determines what is displayed on the schematic.  Double-
   clicking on the parameter (FAST=) will change the number
   of dots.

   One dot:  The Description only will show on schematic.
   Two dots: Both the Name and Description will show.
   No dots:  Neither Name nor Description will show.
