Product Family: Hardware
Product Line: Virtex
Product Part: Virtex General Hardware
Problem Title:
Virtex Configuration: Can CRC be disabled.
Problem Description:
URGENCY: standard
GENERAL DESCRIPTION:
Can you turn on and off the CRC check for Virtex like the 4k familiy?
Solution 1:
No, BitGen does not have a switch to disable CRC for Virtex. The CRC check is different for Virtex
than the XC4000 series and other FPGA families. In previous families, it is checked after each fram
e. For Virtex, it checks just prior to loading the last frame and again at the very end of the bits
tream.
For more information on CRC checking in Virtex refer to Xilinx Application Note xapp138 "Virtex Conf
iguration and Readback".
