DDR4 and DDR3 IP - BFM simulations have errors when using Self Refresh and Self Restore options

Description

Version Found: v2.0

Version Resolved: See (Xilinx Answer 58435)

 

When running a DDR4 IP behavioral simulation with Self Refresh and Self Restore enabled the following error message might be seen:

 

sim_tb_top.mem_model_x16.mem.memModels_Ri2[0].memModel2[0].ddr4_model
.always_diff_ck.if_diff_ck.sref_decode:ERROR: Initialization sequence must be complete prior to cmdSREFE @1937345

When running a DDR3 IP behavioral simulation with Self Refresh and Self Restore enabled the following error message might be seen:

 

 

sim_tb_top.mem_model_x4.memRank[3].memModel[17].u_ddr3_x4.reset: at time 0.0 ps ERROR: CKE must be inactive when RST_N goes inactive.

 

 

Solution

These issues only occur when using the BFM model for simulations and can be safely ignored.
