Microsemi IGLOO2 HPMS Single Error Correct / Double Error Detect

Introduction

The IGLOO2 HPMS has an embedded DDR controller (HPMS DDR). This DDR controller is intended to control an off-chip DDR memory. The HPMS DDR controller can be accessed from the HPMS (using HPDMA) as well as from the FPGA fabric.
When you use System Builder to build a system block which includes an HPMS DDR, System Builder configures the HPMS DDR controller for you based on your entries and selections.
No separate HPMS DDR configuration by the user is required. For details, please refer to the IGLOO2 System Builder User ‘s Guide.
System Builder

Configuration Options

You can configure your EDAC options from the System Builder SECDED page, as shown in Figure 1-1.

Figure 1-1 • Configure EDAC

Expose EDAC_ERROR Bus – Use this option to expose the EDAC_ERROR bus signal to the FPGA fabric where it can be used by your design.
Enable EDAC – Use this option the enable the EDAC functionality for each of the following blocks:

eSRAM_0
eSRAM_1
MDDR

For the eSRAMs, the EDAC Interrupt can be configured in one of four ways (as shown in Figure 1-2):

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)
