Table 8.  Testbench Files
File Name Description
all_modes.mif Memory initialization file (MIF) used for reconfiguration to change speed.
avalon_bfm_wrapper.sv A wrapper for the Avalon BFMs that the avalon_driver.sv file uses.
avalon_driver.sv A SystemVerilog HDL driver that uses the BFMs to form the transmit and receive path, and access the Avalon-MM interface.
avalon_if_params_pkg.sv A SystemVerilog HDL testbench that contains parameters to configure the BFMs. Because the configuration is specific to the DUT, you must not change the contents of this file.
avalon_st_eth_packet_monitor.sv A SystemVerilog HDL testbench that monitors the Avalon-ST transmit and receive interfaces.
default_test_params_pkg.sv A SystemVerilog HDL package that contains the default parameter settings of the testbench.
eth_mac_frame.sv A SystemVerilog HDL class that defines the Ethernet frames. The avalon_driver.sv file uses this class.
eth_register_map_params_pkg.sv A SystemVerilog HDL package that maps addresses to the Avalon-MM control registers.
ptp_timestamp.sv A SystemVerilog HDL class that defines the timestamp in the testbench.
tb_run.tcl A Tcl script that starts a simulation session in the ModelSim simulation software.
  • Without IEEE 1588v2: tb_testcase.sv
  • With IEEE 1588v2: tb_testcase_1588.sv
A SystemVerilog HDL testbench file that controls the flow of the testbench.
tb_top_n.sv
  • Without IEEE 1588v2: tb_top_n.sv
  • With IEEE 1588v2: tb_top_n_1588.sv
The top-level testbench file. This file includes the customized 1G/10GbE MAC, which consists of the device under test (DUT), a client packet generator, and a client packet monitor along with other logic blocks.
wave.do A signal tracing macro script that the ModelSim simulation software uses to display testbench signals.
