5.2.2. Creating Logic Lock (Standard) Regions
You can define a Logic Lock (Standard) region by its height, width, and location; Alternatively, you can specify the size or location of a region, or both, or the Intel® Quartus® Prime software can generate these properties automatically. The Intel® Quartus® Prime software bases the size and location of a region on the contents of the region and the timing requirements of the module.
The Intel® Quartus® Prime software displays Logic Lock (Standard) regions with colors indicating the percentage of resources available in the region. An orange Logic Lock (Standard) region indicates a nearly full Logic Lock (Standard) region.
Intel® Quartus® Prime software cannot automatically define the size of a region if the location is Locked. Therefore, if you want to specify the exact location of the region, you must also specify the size.
