RUNNING the simulation/Testbench in ModelSIM:
Open ModelSIM project: ethernet/sim/rtl_sim/modelsim_sim/bin/ethernet.mpf
Run the macro do.do (write "do do.do" in the command window).
Simulation will be automatically started. Logs are stored in the /log
directory. tb_ethernet test is performed.
RUNNING the simulation/Testbench in Ncsim:
Go to the ethernet\sim\rtl_sim\ncsim_sim\run directory. Run the
run_eth_sim_regr.scr script. Simulation is automatically started. Logs are
stored in the /log directory. Before running the script for another time,
run the clean script that deletes files from previous runs. tb_ethernet test
Why are eth_cop.v, eth_host.v, eth_memory, tb_cop.v and tb_ethernet_with_cop.v
files used for?
Although the testbench does not include the traffic coprocessor, the
coprocessor is part of the ethernet environment. eth_cop multiplexes
two wishbone interface between 4 modules:
- First wishbone master interface is connected to the HOST (eth_host)
- Second wishbone master interface is connected to the Ethernet Core (for
accessing data in the memory (eth_memory)).
- First wishbone slave interface is connected to the Ethernet Core (for
accessing registers and buffer descriptors).
- Second wishbone slave interface is connected to the memory (eth_memory)
so host can write data to the memory (or read data from the memory.
tb_cop.c is a testbench just for the traffic coprocessor (eth_cop).
tb_ethernet_with_cop.v is a simple testbench where all above mentioned
modules are connected into a single environment. Few packets are transmitted
and received. The "main" testbench is tb_ethernet.v file. It performs several
tests (eth_cop is not part of the simulation environment).
