Allows you to specify the currently selected LogicLock™ region's origin.
The origin specifies the location of either the top left corner or the bottom left corner of the region, depending on the device family. For APEX™ 20K, APEX™ II, ARM®-based Excalibur™, and Mercury™ devices, the origin defines the top left corner of the region. For Cyclone™, Stratix™, and Stratix™ GX devices, the origin defines the bottom left corner of the region.
The options available for specifying the origin may vary depending on the device selected.
| Current Origin (top left corner) |
Displays the current location of the LogicLock region's top left corner. This field is displayed for device families for which the LogicLock region origin is the top left corner of the region. |
| Current Origin (bottom left corner) |
Displays the current location of the LogicLock region's bottom left corner. This field is displayed for device families for which the LogicLock region origin is the bottom left corner of the region. |
| Change | Sets the origin of the currently selected LogicLock region to the values selected in the Resource type, MegaLAB™ row name, MegaLAB column number, LAB name, ESB name, Row name, Column number, X coordinate, and/or Y coordinate lists. More Details |
| Resource type | Specifies the type of logic available on the device at the origin; either MegaLAB, LAB logic, or ESB logic. If you specify an origin as a MegaLAB, the Quartus® II software converts this origin to the leftmost Logic Array Block (LAB) or Embedded System Block (ESB) in that MegaLAB before writing it to the Entity Settings File (.esf). |
| MegaLAB row name | Specifies the name of the MegaLAB row at the origin. |
| MegaLAB column number | Specifies the number of the MegaLAB column at the origin. |
| LAB name | Specifies the LAB. This option is available only if the Resource type is LAB logic. |
| ESB name | Specifies the ESB. This option is available only if the Resource type is ESB logic. |
| Row name | Specifies the row name at the origin. |
| Column number | Specifies the column number at the origin. |
| X coordinate | Specifies the X coordinate at the origin. |
| Y coordinate | Specifies the Y coordinate at the origin. |
