The Traffic Generator is not simulating different data and command patterns because "modify_enable_sel" is set to 1 in example_top.v/vhd.
This overrides the DATA_MODE and CMD_PATTERN parameters set in init_mem_pattern_ctr.v/vhd with "data_mode_manual_sel" and "addr_mode_manual_sel."
When "data_mode_manual_sel" and "addr_mode_manual_sel" are set to DGEN_ADDR, the address is used as the data pattern, and SEQUENTIAL address mode by default.
To change the data and command patterns, follow these steps:
- Set DATA_PATTERN and CMD_PATTERN in sim_tb_top.v/vhd.
- Set modify_enable_sel=0 in example_top.v.
- Set DATA_MODE and CMD_PATTERN in init_mem_pattern_ctr.v/vhd.
Starting in the ISE 13.3 release, uses will only have to modify CMD_PATTERN and DATA_PATTERN in sim_tb_top to change the command and data patterns for their simulation.
