The -psip_options command line option is used in place_design to specify a list of optimizations to switch on during Physical Synthesis Phase. This switch can be used to exclude any specific optimization that is being triggered. Optimizatons are only performed if applicable for the given design.
You can specify different options using the following
command:
place_design -psip_options {opt1 opt2}For example, if you want to run only property-based retiming and fanout optimization
during the Physical Synthesis Phase, you can run:
place_design -psip_options {retime fanout_opt}| Optimization | Opt name |
|---|---|
| Critical Cell Optimization | critical_cell_opt |
| Fanout Optimization | fanout_opt |
| Very High Fanout Optimization | very_high_fanout_opt |
| Equivalent Driver Rewire Optimization | equ_drivers_opt |
| DSP Register Optimization | dsp_register_opt |
| Block RAM Register Optimization | bram_register_opt |
| URAM Register Optimization | uram_register_opt |
| Shift Register Optimization | shift_register_opt |
| Property-Based Retiming | retime |
| Per-SLR Replication Optimization | per_slr_replication_opt |
| Shift Register to Pipeline Optimization | shift_register_to_pipeline |
| Auto Pipeline Insertion Optimization | auto_pipeline_insertion |
| Control Set Optimization | control_set_opt |
