Copying the Configuration Space Bypass Mode Example Design
Follow these steps to copy the Configuration Space Bypass Mode Qsys Example Design to your working
directory:
1. Copy the example design,
pcie_cfbp_g2x8_ast256.qsys , from the installation directory: /ip/
altera/altera_pcie/altera_pcie_hip_ast_ed/altera_pcie_cfgbp_ed/qsys_example to your working directory.
2. Copy the Qsys wrapper file for the Configuration Space Bypass application logic,
altera_pcie_cfgbp_ed_
hw.tcl , from the installation directory:
/ip/altera/altera_pcie/altera_pcie_hip_ast_ed/altera_pcie_
cfgbp_ed/ to your working directory.
3. Rename the
pcie_cfbp_g2x8_ast256.qsys top.qys . Renaming is necessary because the testbench defines
top.v
as the top-level wrapper. Qsys creates
top.v
from
top.qsys
when you generate the system.
4. Start Qsys by typing
qsys-edit
and open top.qsys when prompted by Qsys.
The following figure shows the complete system.
