5.2.4. Placing Logic Lock (Standard) Regions

A fixed region must contain all resources required by the design block assigned to the region. Although the Intel® Quartus® Prime software can automatically place and size Logic Lock (Standard) regions to meet resource and timing requirements, you can manually place and size regions to meet your design requirements.

If you manually place or size a Logic Lock (Standard) region:

  • Logic Lock (Standard) regions with pin assignments must be placed on the periphery of the device, adjacent to the pins. You must also include the I/O block within the Logic Lock (Standard) Region.
  • Floating Logic Lock (Standard) regions can overlap with their ancestors or descendants, but not with other floating Logic Lock (Standard) regions.
