The CRC circuit continues running even if an error occurs. When a soft error occurs,
the device sets the CRC_ERROR pin high. Two types of CRC detection check the

For each frame of data, the pre-calculated 16-bit CRC enters the CRC circuit
right at the end of the frame data and determines whether or not there is an
error.
If an error occurs, the search engine starts to find the location of the error.
You can shift the error messages out through the JTAG instruction or core
interface logic while the error detection block continues running.
The JTAG interface reads out the 16-bit CRC result for the first frame and also
shifts the 16-bit CRC bits to the 16-bit CRC storage registers for test purposes.
You can deliberately introduce single error, double errors, or double errors
adjacent to each other to configuration memory for testing and design
verification.
During configuration, after a frame of data is loaded into the Stratix III device,
the pre-computed CRC is shifted into the CRC circuitry.
At the same time, the CRC value for the data frame shifted-in is calculated. If
the pre-computed CRC and calculated CRC values do not match, nSTATUS is
set low. Every data frame has a 16-bit CRC; therefore, there are many 16-bit
CRC values for the whole configuration bitstream. Every device has different
lengths of the configuration data frame.
Figure 15–1
