1.9.2. Changing Partition Placement with LogicLock Changes
Similarly, if a partition’s placement is preserved, and the partition is assigned to a LogicLock region, the Fitter always reuses the corresponding LogicLock region size specified in the post-fit netlist. That is, changes to the LogicLock Size setting do not initiate refitting if a partition’s placement is preserved with the Post-Fit netlist type, or with .qxp that includes post-fit information.
However, you can use the LogicLock Origin location assignment to change or fine‑tune the previous Fitter results. When you change the Origin setting for a region, the Fitter can move the region in the following manner, depending upon how the placement is preserved for that region's members:
- When you set a new region Origin, the Fitter uses the new origin and replaces the logic, preserving the relative placement of the member logic.
- When you set the region Origin to Floating, the following conditions apply:
- If the region’s member placement is preserved with an imported partition, the Fitter chooses a new Origin and re-places the logic, preserving the relative placement of the member logic within the region.
- If the region’s member placement is preserved with a Post-Fit netlist type, the Fitter does not change the Origin location, and reuses the previous placement results.
