The following Primitive Groups correlate to the PRIMTIVE_GROUP cell property in the Vivado software. Similarly, the listed Primitive Subgroup correlates to the PRIMTIVE_SUBGROUP property on the cells in the software. These can be used in filters to specify a class of cells for constraint processing and other tasks within Vivado.
