IPexpress allows you to implement Error Check Codes (ECC) in the Embedded Block Ram (EBR) based memory modules. There is a checkbox to enable ECC in the configuration tab for the module. If you choose to use ECC, you will have a 2-bit error signal and the error codes are defined below:
- Error[1:0]="00"- Indicates there is no error.
- Error[1:0]="01"- Indicates there was a 1-bit error which was fixed.
- Error[1:0]="10"- Indicates there was a 2-bit error which cannot be corrected.
- Error[1:0]="11"- Not used.
