User Guide
■ pcie_reconfig_driver_0—This Avalon-MM master drives the Transceiver
Reconfiguration Controller. The pcie_reconfig_driver_0 is implemented in clear
text that you can modify if your design requires different reconfiguration
functions. After you generate your Qsys system, the Verilog HDL for this
component is available as: <working_dir>/<variant_name>/testbench/
<variant_name>_tb/simulation/submodules/altpcie_reconfig_driver.sv.
■ Transceiver Reconfiguration Controller—The Transceiver Reconfiguration
Controller dynamically reconfigures analog settings to improve signal quality. For
Gen1 and Gen2 data rates, the Transceiver Reconfiguration Controller must
perform offset cancellation and PLL calibration.
Generating the Testbench
Follow these steps to generate the chaining DMA testbench:
1. On the Qsys Generation tab, specify the parameters listed in the following table.
2. Click the Generate button at the bottom of the Generation tab to create the
chaining DMA testbench.

None. (This option generates a simulation model you can include in your own
custom testbench.)
