If the IP requires a license key, the key must be verified. The AMD Vivado™ design tools have several license checkpoints for gating licensed IP through the flow. If the license check succeeds, the IP can continue generation. Otherwise, generation halts with an error. License checkpoints are enforced by the following tools:

  • Vivado Synthesis
  • Vivado Implementation
  • write_bitstream (Tcl command)
Note: IP license level is ignored at checkpoints. The test confirms a valid license exists. It does not check IP license level.

If a Hardware Evaluation License is being used, the core stops transmitting HDMI Stream after timeout. This timeout is based on system CPU clock. For example, if system is running at 100 MHz, the IP times out after approximately 4 hours of normal operation when Hardware Evaluation License is being used.
