CPLD: XC9500: What are the recommended maximum rise times for inputs?
Problem Description:
Urgency: Standard
General Description: Questions have risen concerning the
maximum rise time suggested for an input signal on a 9500
device.
Solution 1:
The suggested maximum rise time for a signal that is routed
to combinatorial logic is 50ns.
For signals that use the global routing resources (Global
Clock, Global Output Enable and Global Set/Reset), it is
recommended that the maximum rise time not exceed 10ns.
