Virtex Spartan-II Configuration - Can CRC be disabled?


General Description:

Can you turn on and off the CRC check for Virtex or Spartan-II as you can for

the 4k family?


No, BitGen does not have a switch to disable CRC for Virtex or Spartan-II. The

CRC check is differs between these and the XC4000 series and other FPGA

families. In previous families, CRC is checked after each frame. For Virtex and

Spartan-II, a check occurs just prior to loading the last frame and again at the

very end of the bitstream.

For more information on CRC checking in Virtex refer to Xilinx Application
