■
Test Driver (altpcietb_bfm_driver_rp.v)—the chaining DMA endpoint test driver
which configures the root port and endpoint for DMA transfer and checks for the
successful transfer of data. Refer to the
“Test Driver Module” on page 15–18
for a
detailed description.
You can use the example root port design for Verilog HDL simulation. All of the
modules necessary to implement the example design with the variation file are
contained in <variation_name>_example_rp_pipen1b.v. This file is created in the
<variation_name>_examples/root_port subdirectory of your project when the IP
Compiler for PCI Express variation is generated.
The parameter editor creates the variation files in the top-level directory of your
project, including the following files:
■
<variation_name>.v—the top level file of the IP Compiler for PCI Express variation.
The file instantiates the SERDES and PIPE interfaces, and the parameterized core,
<variation_name>_core.v.
■
<variation_name>_serdes.v —contains the SERDES.
■
<variation_name>_core.v—used in synthesizing <variation_name>.v.
■
<variation_name>_core.vo—used in simulating <variation_name>.v.
The following modules are generated for the design example in the subdirectory
<variation_name>_examples/root_port:
