Importing Previously Synthesized Netlists - 2023.1 English

Vivado Design Suite User Guide: Implementation (UG904)

2023.1 English

The Vivado Design Suite supports netlist-driven design by importing previously synthesized netlists from AMD or third-party tools. The netlist input formats include:

  • Structural Verilog
  • Structural SystemVerilog
  • EDIF
  • Synthesized Design Checkpoint (DCP)
Important: NGC format files are not supported in the Vivado Design Suite for UltraScale and later devices. It is recommended that you regenerate the IP using the Vivado Design Suite IP customization tools with native output products. Alternatively, convert_ngc Tcl utility to convert NGC files to EDIF or Verilog formats. However, AMD recommends using native Vivado IP rather than XST-generated NGC format files going forward.
Important: When using IP in Project Mode or Non-Project Mode, always use the XCI file and not the DCP file. This ensures that IP output products are used consistently during all stages of the design flow. If the IP was synthesized out-of-context and already has an associated DCP file, the DCP file is automatically used and the IP is not re-synthesized. For more information, see section Adding Existing IP to a Project in the Vivado Design Suite User Guide: Designing with IP (UG896).
