7.6.1. eco_load_design and eco_commit_design Commands


  • eco_load_design—loads the final netlist in the ECO context.
  • eco_commit_design—commits the ECO modified netlist to disk while running in interactive mode.


The following example shows an interactive ECO session to modify the lut_x lutmask for project top. If the ECO modifications are legal, the eco_commit_design command commits the final netlist.

$ quartus_fit -s
>> load_package eco
>> project_open top
>> eco_load_design
>> modify_lutmask -to lut_x -eqn B&C # some ECO changes
>> eco_commit_design
>> project_close
