Table 1–8 shows the recommended device speed grades for earlier device families that
the RapidIO IP core supports.
Release Information
Table 1–9 provides information about this release of the RapidIO IP core.
Altera verifies that the current version of the Quartus II software compiles the
previous version of each IP core. Any exceptions to this verification are reported in the
MegaCore IP Library Release Notes or in the errata for the RapidIO IP core in the
Knowledge Base . Altera does not verify compilation with IP core versions older than
the previous release.

Notes to Table 1–8 :
(1) In this table, the entry -n indicates that both the industrial speed grade In and the commercial speed grade Cn are supported for this device
family, RapidIO mode, and baud rate.
(2) Not supported for this device family.
(3) Altera recommends that for designs that include a 4× 5.0 Gbaud RapidIO IP core variation and that target a -3 speed grade Stratix IV GX device,
you use multiple seeds in the Quartus II Design Space Explorer to find the optimal Fitter settings to meet the timing constraints. Following the
Timing Advisor's recommendations, including optimizing for speed and using LogicLock regions may be necessary to meet timing, especially
for more complex variations implemented in the largest devices.
(4) The RapidIO IP core supports only the EP4CGX50, EP4CGX75, EP4CGX110, and EP4CGX150 Cyclone IV GX devices.
(5) Some simple Cyclone IV GX 4× variations, such as physical-layer-only variations, may meet timing at 2.5 Gbaud in -7 speed grade devices, after
following the Timing Advisor’s recommendations.
