The testbench has several VHDL generics/Verilog HDL parameters that control the
overall operation of the testbench. These generics are described in
The root port testbench is provided in the subdirectory <variation_name>_examples/
root_port/testbench in your project directory. The top-level testbench is named

testbench.
This testbench simulates up to an ×8 PCI Express link using either the PIPE interfaces
of the root port and endpoints or the serial PCI Express interface. The testbench
design does not allow more than one PCI Express link to be simulated at a time. The
top-level of the testbench instantiates four main modules:

Selects the PIPE interface (PIPE_MODE_SIM=1) or the serial
interface (PIPE_MODE_SIM= 0) for the simulation. The PIPE
interface typically simulates much faster than the serial
interface. If the variation name file only implements the PIPE
interface, then setting PIPE_MODE_SIM to 0 has no effect and
the PIPE interface is always used.
Controls how many lanes are interconnected by the testbench.
Setting this generic value to a lower number simulates the
endpoint operating on a narrower PCI Express interface than
the maximum.
If your variation only implements the ×1 IP core, then this
setting has no effect and only one lane is used.
Setting this parameter to a 1 speeds up simulation by making
many of the timing counters in the PCI Express IP core operate
faster than specified in the PCI Express specification.This
parameter should usually be set to 1, but can be set to 0 if there
is a need to simulate the true time-out values.
