To configure the Error Detection and Correction (EDAC) options for the eSRAM and MDDR blocks using System Builder, follow these steps:
1. **Access System Builder:** Open the System Builder tool for the Microsemi IGLOO2 HPMS.
2. **Navigate to SECDED Page:** Go to the SECDED page within System Builder to configure the EDAC options.
3. **Configure EDAC Options:**
- **Expose EDAC_ERROR Bus:** Use this option to expose the EDAC_ERROR bus signal to the FPGA fabric for use in your design.
- **Enable EDAC:** Enable the EDAC functionality for each of the following blocks:
- eSRAM_0
- eSRAM_1
- MDDR
- For the eSRAMs, you can configure the EDAC Interrupt in one of four ways:
- None (for no Interrupts)
- 1-bit Error (Interrupts when there is a 1-bit error)
- 2-bit Error (Interrupts when there is a 2-bit error)
- 1-bit and 2-bit Error (Interrupts when BOTH 1-bit error AND 2-bit error occur)
4. **Port Description:** Refer to Table 2-1 in the manual for a description of the EDAC_BUS ports and their directions.
5. **Save Configuration:** Once you have made the necessary EDAC configurations, save your settings in System Builder.
By following these steps in System Builder, you can easily configure the Error Detection and Correction options for the eSRAM and MDDR blocks in the Microsemi IGLOO2 HPMS according to the user manual provided.
