EDK Obsoleted Cores

Xilinx recommends that you use the latest version of EDK IP cores whenever possible to access the latest enhancements and architecture support.

This page lists the EDK cores that have been removed from the releases of Xilinx Platform Studio (XPS) from the 12.1 release to the present. Newer versions and suggested replacements are displayed where available.

Note: The suggested IP replacements may not be supported in older FPGA families, and that suggested replacements may not deliver 1:1 correspondence of features. Consult the IP documentation before making IP replacements.
