6.5.5. ECC Error Status

You can read the status of various registers used by the ECC feature, using the APB interface.

ECC registers provide the following information – and corresponding APB addresses – for Pseudo Channel 0 and Pseudo Channel 1:

  • Single-bit error (SBE) counter
  • Double-bit error (DBE) counter
  • Logical address (AXI address) of the first single-bit error
  • Logical address (AXI address) of the first double-bit error
  • Read transaction ID (AXI) of the first single-bit error
  • Read transaction ID (AXI) of the first double-bit error
  • Read Data Parity error counter

The values of the ECC registers are read when the PRREADY output from the HBM2 controller is asserted. When the HBM2 controller is RESET, these register values are reset to zero.

Table 38.  ECC Registers
Address Read Data Bit Location Description

16’h0120 – PC0

16’h0220 – PC1

 [7:0]

Single-Bit-Error Counter. The counter does not overflow when value reaches maximum.

Write 0 to clear the counter. Clearing the counter does not clear this valid bit or vice-versa. You must issue a separate write command to valid and counter to clear both registers.

[15:8] Reserved.

16’h0122 – PC0

16’h0222 – PC1

 [7:0]

Double-Bit-Error Counter. The counter does not overflow when value reaches maximum.

Write 0 to clear the counter. Clearing the counter does not clear this valid bit or vice-versa. You must issue a separate write command to valid and counter to clear both registers.

[15:8] Reserved.

16’h0124 – PC0

16’h0224 – PC1

[15:0] First SBE logical address (lower order). This is the logical address of the first single-bit error, corresponding to the lower 16 bits of the AXI Address bus.

16’h0126 – PC0

16’h0226 – PC1

 [15:0] First SBE logical address (higher order). This is the logical address of the first single-bit error, corresponding to the higher 16 bits of the AXI address bus. The higher order 4 bits in 4GB configuration and higher-order 3 bits in 8GB configuration are padded with zeros.

16’h0128 – PC0

16’h0228 - PC1

 [15:0] First DBE logical address (lower order). This is the logical address of the first double-bit error, corresponding to the lower 16 bits of the AXI address bus.

16’h012A – PC0

16’h022A – PC1

[15:0] First DBE logical address (higher order). This is the logical address of the first double-bit error, corresponding to the higher 16 bits of the AXI address bus. The higher order 4 bits in 4GB configuration and higher order 3 bits in 8GB configuration are padded with zeros.

16’h012C – PC0

16’h022C – PC1

 [8:0] Read Transaction ID of the first single-bit error.
[15:9] Reserved.

16’h012E – PC0

16’h022E – PC1

 [8:0] Read Transaction ID of the first double-bit error.
[15:9] Reserved.

16’h0130 – PC0

16’h0230 – PC1

 [7:0]

Read Data Parity Error Count. The counter does not overflow when value reaches maximum.

Write 0 to clear the counter. Clearing the counter does not clear this valid bit or vice-versa. You must issue a separate write command to valid and counter to clear both registers.

[15:8] Reserved.
