3 Generating the Intel Stratix 10 MX HBM2 IP
Description
Runs the default traffic pattern after reset. The default
traffic pattern consists of sequential transactions.
Enable this parameter if you want to run a custom traffic
pattern after reset.
The traffic generator does not assert a pass or fail until you
configure it and signal it to start through its Avalon
configuration interface.
To configure the traffic generator, you connect using the
EMIF Debug Toolkit, or through custom logic connected to
the Avalon-MM configuration slave port on the traffic
generator.
You can simulate configuration using the example testbench
provided in the
altera_hbm_tg_axi_tb.sv
Causes the traffic generator to issue traffic with different
read/write IDs, regardless of whether you enable the
reorder buffer on the Controller tab. When you do enable
the reorder buffer, the traffic generator automatically
generates transactions with different IDs.
The use of different read/write IDs results in higher
efficiency, but – because the traffic generator logic does not
handle read data returning out-of-order – data mismatches
in simulation can result if you disable the reorder buffer.
