Lattice Diamond: How do we tell the software to reduce the DSP block utilization and use LUTs instead?
Lattice Synthesis Engine (LSE) has the ability to reduce the total DSP block utilization using these steps:
- Go to Project > Active Implementation > Select Synthesis Tool
- Select "Lattice LSE" and click OK.
- Go to Project > Active Strategy > LSE Settings
- Set DSP style to "DSP"
- Experiment with DSP utilization value (ex. 50%)
- Map your design to see if DSP utilization changes.
