MIG 7 Series AXI, ECC Enabled, 4:1 - dbg_rddata_r is half the width of dbg_rddata


Version Found: v2.0
Version Resolved: See (Xilinx Answer 54025)

For MIG 7 Series AXI, ECC Enabled, and 4:1 clock ratio designs, "dbg_rddata_r" is only half the width of "dbg_rddata". Therefore, when an ECC error occurs, half of the registered data is lost.


To fix the issue, apply the following RTL changes to mig_7series_2_0_memc_ui_top_axi.v.


Line 960: reg [4*DQ_WIDTH-1:0]         dbg_rddata_r;


Line 960:     reg [2*nCK_PER_CLK*DQ_WIDTH-1:0]         dbg_rddata_r;
