Compiler

Incremental synthesis



Turning on Save a node-level netlist into a persistent source file directs the Compiler to save synthesis results for the current compilation focus as an ATOM-based netlist in Verilog Quartus® Mapping File (.vqm) format.

The File name box specifies the name of the VQM File to which the Compiler should save synthesis results. By default, the Quartus® II software places the VQM File in the atom_netlists directory under the current project directory. You can direct the Quartus II software to place this file in a different directory by specifying the directory path in the File name box. However, the Quartus II software cannot place the VQM File in the same directory as the current project.

If you are already compiling from EDIF Input Files (.edf) or VQM Files, which are ATOM-based netlists, you do not need to perform incremental synthesis with the Quartus II software.
