General Information

Supported devices can be found in the following locations:

For a list of new features and added device support for all versions, see the Change Log file available with the core in Vivado tools.

Table 1 correlates the core version to the first Vivado design tools release version in which it was included.

v5.02014.1

* Starting with the release of Vivado 2015.3, the MIG wizard is no longer used. A separate wizard exists for all supported memory interface types. Therefore, the core versions reset to 1.0.

For a list of supported memory interfaces and features for UltraScale FPGAs, see the LogiCORE IP UltraScale Architecture-Based FPGAs Memory Interface Solutions Product Guide (PG150) located at:

https://www.xilinx.com/products/technology/memory-interfacing/index.htm

For a complete list of supported memory devices please refer to the attached spreadsheet called "memory_device_support_qdriiplus.xlsx".


For a list of supported frequencies for UltraScale FPGAs Memory Interfaces, see the appropriate DC and Switching Characteristics Data Sheet available in the UltraScale Documentation Center.

For supported simulators, see the Xilinx Design Tools: Release Notes Guide.

The MIG tool includes the appropriate frequency range for each specific memory interface configuration

Table 2 provides answer records for general guidance when using the MIG UltraScale core.
