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 III device family.

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, as shown in Figure 11–2.

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

in Table 11–5 on page 11–6.

1 The divisor value divides down the frequency of the configuration

oscillator output clock. This output clock is used as the clock source for the

error detection process.

8. Click OK.
