15 years ago --- Quote Start --- can please you explain more about conduits? --- Quote End --- Conduits are the signals from your Avalon component that are not related to the Avalon bus. For example, a PCI core for use with the Avalon bus would technically be called a PCI-to-Avalon bridge, since it maps between the two protocols. In its simplest form, the bridge would be a PCI target. A PCI target cannot become a master of the PCI bus. The PCI-to-Avalon bridge would have a PCI target interface, and an Avalon-MM master interface. The signals for the Avalon-MM master interface would connect to the SOPC system. The signals for the PCI target interface would be marked as conduit signals in the SOPC _hw.tcl file. When you generate the SOPC system, those conduit signals will be present as signals on the top-level component. You then connect those to the PCI signals on the FPGA pins. Is that clearer?
