Problem Title:
CPLD XC9500: Minimum reset signal pulse width
Problem Description:
Urgency : Standard
General Description:
What is the minimum reset pulse width for 9500 parts?
Solution 1:
Currently we do not spec the XC9500 RESET pulse width.
To gain an approximation of this value, use the tPD spec.
This spec for 'I/O to Output Valid', is listed in the XC9500
data sheets for all of the various speed grades, and also
shown below:
SPEED
GRADE tPD (or approximation for RESET pulse width)
--------------------------------------------------------------
-5 5.0ns
-6 6.0ns
-7 7.5ns
-10 10.0ns
-15 15.0ns
-20 20.0ns
