6.5.6. Optimize Settings with Design Space Explorer II
In DSE II, an exploration point is a collection of Analysis & Synthesis, Fitter, and placement settings, and a group of exploration points is a design exploration. A design exploration can also include different fitter seeds.
DSE II compiles the design using the settings corresponding to each exploration point. When the compilation finishes, DSE II evaluates the performance data against an optimization goal that you specify. You can direct the DSE II to optimize for timing, area, or power.
If a design is close to meeting timing or area requirements, you can try different seeds with the DSE II, and find one seed that meets timing or area requirements.
You can run DSE II at any step in the design process; however, because large changes in a design can neutralize gains achieved from optimizing settings, Intel® FPGA recommends that you run DSE II late in the design cycle.
- The number or type of CPUs that DSE II uses to perform the seed sweeps
- Any change to the operating system
- Any change to source file content or location
- Any change to the Compiler settings or Timing Analyzer settings
