License Keys for Xilinx LogiCORE IP Cores

Overview

  • Selected Xilinx® software and most fee-based LogiCORE™ IP cores require a FLEXNet license key to enable use by customers.

Xilinx Software Tools

  • FLEXNet license keys are required by certain Xilinx software tools. See the Licensing FAQ for more information.
  • Xilinx LogiCORE IP cores licensed with ISE® Design Suite Software at no additional charge do not require afn additional key.

Fee-based LogiCORE IP Cores

  • Simulation Only Keys
    • Simulation Only keys allow you to perform functional simulation only. They are shipped with the ISE® software for most fee-based LogiCORE IP cores.
  • Hardware Evaluation Keys
    • Hardware Evaluation keys allow you to simulate and implement your design, run timing analysis and generate a time-limited bitstream to program a Xilinx FPGA. The core in the programmed device will function in hardware for anywhere from 2 to 8 hours, depending on the core.
    • Hardware Evaluation keys for Processor IP cores are shipped with the ISE Design Suite Embedded Edition software.
    • You can generate a Hardware Evaluation key for most fee-based LogiCORE IP at the Xilinx Software and IP Licensing Center
  • Keys for Production Use
    • Full License keys enable production use of the IP core, including simulation, implementation, timing analysis, and programming a Xilinx FPGA to perform hardware validation with no timeout period.
    • After purchasing a license for a fee-based core, you can generate a Full key for it on the Xilinx Software and IP Licensing Center.
