Altera Arria 10 Avalon-ST - Manual (Page 22)

The example design includes the following components:
• DUT—This is Gen1 ×8 Endpoint. For your own design, you can select the data rate, number of lanes,
and either Endpoint or Root Port mode.
• APPS—This Root Port BFM configures the DUT and drives read and write TLPs to test DUT
functionality. An Endpoint BFM is available if your PCI Express design implements a Root Port.
Generating the Testbench
1. On the Generate menu, select Generate Testbench System. Specify the parameters listed in the
following table.
Table 2-1: Parameters to Specify on the Generation Tab in Qsys
Parameter Value
Testbench System
Create testbench Qsys system Standard, BFMs for standard Qsys interfaces
Create testbench simulation model Verilog
Allow mixed-language simulation Turn this option off
Output Directory
Clear output directories for selected generation
targets
Turn this option off
Testbench /ep_g1x8_tb/
2. Click the Generate button at the bottom of the Generation tab to create the testbench.
Note: This testbench assumes that you are running the DMA application that the example design
available in the installation directory creates. Otherwise, the testbench tests will probably fail unless
your own testbench has equivalent functionality.
Simulating the Example Design
1. Start your simulation tool. This example uses the ModelSim ® software.
2. From the ModelSim transcript window, in the testbench directory,
/ep_g1x8_tb/ep_g1x8_
tb/sim/mentor , type the following commands:
a.
do msim_setup.tcl
b.
ld_debug
(This command compiles all design files and elaborates the top-level design without any
optimization.)
c.
run -all
