Table 34.  Attributes of Logic Lock Regions
Name Value Behavior
Width Number of columns

Specifies the width of the Logic Lock region.

If Size/State is set to Auto/Floating, the attribute is set to Undetermined.

Height Number of rows

If Size/State is set to Auto/Floating, the attribute is set to Undetermined.

Origin Any Floorplan Location Specifies the location of the Logic Lock region on the floorplan. The origin is at the lower left corner of the Logic Lock region.
Reserved Off | On Prevents the Fitter from placing other logic in the region. You cannot apply the Reserved assignment to routing regions.
Core-Only Off | On Excludes periphery resources from a region. Unlike the Intel® Quartus® Prime Standard Edition software, Intel® Quartus® Prime Pro Edition region assignments apply to periphery resources by default. If the region is designated as Reserved and Core Only, periphery resources are not reserved from the region.
Size/State Fixed/Locked | Auto/Floating Specifies whether you or the Fitter determine the size and placement of the Logic Lock region.
  • If set to Fixed/Locked, the default value, you define the Logic Lock region's size and placement.
  • If set to Auto/Floating, the Fitter determines the size and placement of the Logic Lock region.
Routing Region Unconstrained | Whole Chip | Fixed with Expansion | Custom Type of routing region. For more details, refer to Defining Routing Regions.
