Emerald Rapids (EMR) is the first CPU to support Array BIST. Array BIST performs tests on some portions of the core logic such as caches and register files. These are different portions of the silicon compared to the parts tested by Scan at Field (SAF). Unlike SAF, Array BIST doesn't require any test content to be loaded.
