For existing Qsys Avalon-MM designs created in the Quartus II 12.0 or earlier release,
you must re-enable the BARs in 12.1.
For more information about the use of BARs to translate PCI Express addresses to
Avalon-MM addresses, refer to
“PCI Express-to-Avalon-MM Address Translation
for Endpoints for 32-Bit Bridge” on page 7–20 . For more information about
minimizing BAR sizes, refer to “Minimizing BAR Sizes and the PCIe Address
Space” on page 7–21 .
3. For the Device Identification Registers, specify the values listed in the center
column of Table 3–4 . The right-hand column of this table lists the value assigned to
Altera devices. You must use the Altera values to run the Altera testbench. Be sure
to use your company’s values for your final product.
