Device Support Levels
IP core device support levels are generally the same as the level of device support provided by Quartus® II software. Table 1 below defines the support levels and Table 2 indicates the current status. Note that only those devices that did not have final device support in the previous software v14.0 release are listed in the table below. Any exceptions for the software v14.1 release where the IP core device support does not match the Quartus II software device support will be indicated in the MegaCore IP Library Release Notes and Errata (PDF).

|FPGA Device Families|
The IP core is verified with preliminary timing models for this device family. The IP core meets all functional requirements, but might still be undergoing timing analysis for the device family. It can be used in production designs with caution.
| Final Support
The IP core is verified with final timing models for this device family. The IP core meets all functional and timing requirements for the device family and can be used in production designs.
