Enabling the CRC error detection feature in the Quartus II software generates the
CRC_ERROR output to the optional dual purpose CRC_ERROR pin.
To enable the error detection feature using CRC, perform the following steps:
1. Open the Quartus II software and load a project using Cyclone IV devices.
2. On the Assignments menu, click Settings. The Settings dialog box appears.
3. In the Category list, select Device. The Device page appears.
4. Click Device and Pin Options. The Device and Pin Options dialog box appears as
5. In the Device and Pin Options dialog box, click the Error Detection CRC tab.
6. Turn on Enable error detection CRC.
7. In the Divide error check frequency by box, enter a valid divisor as documented
8. Click OK.

Table 9–5 on page
The divisor value divides the frequency of the configuration oscillator
output clock. This output clock is used as the clock source for the error
detection process.
