Licensing - When is a LogiCORE IP Core license checked?

Description

When is a LogiCORE IP Core license checked?

Solution

In ISE Design Suite, aLogiCORE IP Core license is checked:

  • When the LogiCORE IP Core customization GUI is opened, in order to give you advanced notice of the license status.
  • Core generation checks for the license status and embeds the license level (full, simulation, eval) into the LogiCORE IP Core netlist.
  • XST will check a license if the IP core is generated during the synthesis process (This is most common in EDK flows).
  • During NGDBUILD checks both the embedded license information in each licensed LogiCORE IP Core netlist and current license for each LogiCORE IP Core being used in a design.
  • BitGen checks the combined embedded license value for all licensed cores in the design. Any simulation-only licensed IP core in the design will prevent bitstream generation.

In Vivado, aLogiCORE IP Core license is checked:

  • When the LogiCORE IP Core customization GUI is opened, in order to give you advanced notice of the license status.
  • Core generation checks for the license status and embeds the license level (full, simulation, eval) into the LogiCORE IP Core netlist.
  • Synthesischecks both the embedded license information in each licensed LogiCORE IP Core netlist and current license for each LogiCORE IP Core being used in a design.
  • Implementation checks both the embedded license information in each licensed LogiCORE IP Core netlist and current license for each LogiCORE IP Core being used in a design.
  • Bit Generation checks the combined embedded license value for all licensed cores in the design. Any simulation-only licensed IP core in the design will prevent bitstream generation.
