EDCRC Check-Bits Updates

Frame-based check-bits are calculated on-chip during configuration. Column-based check-bits are updated after configuration.

When you enable the EDCRC feature, after the device enters user mode, the EDCRC function starts reading CRAM frames. The data collected from the read-back frame is validated against the frame-based check-bits.

After the initial frame-based verification is completed, the column-based check-bits is calculated based on the respective column CRAM. The EDCRC hard block recalculates the column-based check-bits in one of the following scenarios:

  • FPGA re-configuration
  • After successful partial reconfiguration (PR) session
  • After configuration via protocol (CvP) session
