The Link Model setting controls how out-of-context (OOC) modules and design checkpoint (DCP) sources are represented in the elaborated design. Select one of the following options:

Use RTL model for OOC modules & Netlist model for DCP
  • Generates targets for OOC IP (if not already generated).
  • Pulls RTL sources from the generated output directory.
  • Shows the actual RTL elaborated view for OOC modules without requiring full OOC synthesis runs.
  • Links DCP sources using their synthesized netlist.
Use RTL model for OOC modules & Blackbox model for DCP
  • Generates targets for OOC IP (if not already generated).
  • Pulls RTL sources from the generated output directory.
  • Shows the actual RTL elaborated view for OOC modules without requiring full OOC synthesis runs.
  • Treats DCP sources as black boxes using stub files.
Use Netlist model for both OOC modules & DCP
  • Launches OOC synthesis runs for all the OOC modules.
  • Stitches the synthesized netlist into the elaborated design.
  • Links DCP sources using their synthesized netlist.
  • Default behavior recommended for full netlist consistency.
Use Blackbox model for both OOC modules & DCP
  • Launches OOC synthesis runs for all the OOC modules.
  • Stitches stub files (black boxes) into the elaborated design.
  • Treats DCP sources as black boxes using stub files.
  • Useful for quick structural exploration without netlist details.
