Serial RapidIO™ protocol is not supported for Cyclone® IV GX transceivers in F324 and smaller packages. In these packages, the following protocols are supported:
- PCI Express (PIPE) Gen1 at 2.5 Gbps
- Gigabit Ethernet at 1.25 Gbps
- proprietary protocols using Basic functional mode for data rate up to 2.5 Gbps
Quartus® II software version 10.0 and earlier incorrectly allow design compilation for Cyclone IV GX transceivers in F324 and smaller packages when configured in Serial RapidIO functional mode (with data rates less than 2.5 Gbps). To compile design with transceivers in Serial RapidIO mode up to 3.125 Gbps, select Cyclone IV GX devices in F484 and larger packages.
