Problem Title:
CPLD : XC9500/XL:Is there a reset or a done pin for CPLDs to determine if the device runs
correctly?
Problem Description:
URGENCY: Standard
DESCRIPTION:
The configuration and powerup for CPLDs is different than FPGAs.
Solution 1:
There is no RESET or DONE pin for 9500/XL devices.
The only to verify that the configuration was loaded correctly is to
perform a JTAG Verify operation. This will readback the configuration
registers of the CPLD and compare them to the JEDEC file and determine
if the two differ.
