Critical Issue
For memory interfaces created with version 11.0 or later of the high-performance controller II (HPC II), DDR3 ODT failures can occur in simulation with Denali.
There are two possible workarounds for this issue:Option 1:
Open the alt_mem_ddrx_controller_st_top.v file
and
add 1 (clk) to the equation used to derive the localparams
CFG_EXTRA_CTL_CLK_RD_TO_WR_DIFF_CHIP
and CFG_EXTRA_CTL_CLK_WR_TO_RD_DIFF_CHIP
.Option
2: Open the generated file <variation_name>_alt_mem_ddrx_controller_top.v
and
change the localparam CFG_READ_ODT_CHIP
value to ‘h0
.
