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
