I have a project in XPS 14.1 with axi_7series_ddrx(v1.04a) configured with the DATA WIDTH set to 72-bit and ECC enabled.
I have selected MT41J256M8XX-107 as the memory part and left the other settings at the default values.
I am receiving the errors below:
ERROR:HDLCompiler:532 - "C:/Xilinx/14.1/ISE_DS/EDK/hw/XilinxProcessorIPLib/pcores/axi_7series_ddrx_v1_04_a/hdl/ver
ilog/axi_ctrl_reg_bank.v" Line 284: Index <27> is out of range [26:0] for signal <ecc_err_addr_real>.
ERROR:HDLCompiler:532 - "C:/Xilinx/14.1/ISE_DS/EDK/hw/XilinxProcessorIPLib/pcores/axi_7series_ddrx_v1_04_a/hdl/ver
ilog/axi_ctrl_reg_bank.v" Line 283: Index <27> is out of range [26:0] for signal <ecc_err_addr_swap_row_bank>.
The width of "ecc_err_addr_real" and "ecc_err_addr_swap_row_bank" are determined by the parameter P_MC_ERR_ADDR_WIDTH in the top module (for example axi_7series_ddrx.v).
For XPS 14.1, the parameter P_MC_ERR_ADDR_WIDTH in axi_7series_ddrx.v is fixed at 28.
The P_MC_ERR_ADDR_WIDTH should be a calculated value instead of a fixed value as seen below:
localparam P_MC_ERR_ADDR_WIDTH = ((C_CS_WIDTH == 1) ? 0 : P_RANK_WIDTH) + C_BANK_WIDTH + C_ROW_WIDTH + C_COL_WIDTH + P_DATA_BUF_OFFSET_WIDTH;
This issue is resolved in XPS 14.2.
