I'm trying to instantiate just the PCIe PIPE PHY in a Stratix IV GX part, for use with a non-Altera soft IP core. The mega-wizard utility seems to let me use the PCI Express Compiler to instantiate a whole hard/soft Altera PCIe controller, but I only want to instantiate the PHY part. That option is greyed out in the mega-wizard though. Is that a separate feature that needs to be licensed or something? The documentation does not make this clear.
For Stratix IV GX you need to use ALTGX to get just the PCIe PHY. The PCIe PIPE PHY is just for Stratix V and later families.Start the MegaWizard Plug-In manager and make sure the device family is set to Stratix IV. Then select ALTGX from the Installed Plug-Ins in the I/O folder. Once the ALTGX wizard opens, select PCI Express (PIPE) in the "Which protocol will you be using?" drop sown menu.
