Too many changes to list them all out, but in summary, SafeTI core overhaul to introduce the 3-stage pipeline topology, a custom AMBA AXI4 interface tested on SELENE platform (which may be expanded in the future), the wrappers for SELENE AMBA AHB and AXI4 SafeTI instantiation, core and AXI4 testbenches, two new descriptors that are reserved for now, to name a few.
