Design ROM that has 16 locations each 32 bits wide. The 16 locations have the values like 0xDEADBEEF, 0xCAFEBABE, 0xDEADFEED and so on of your choice. There will be a chipselect (CS) input that activates the chip. The address input to the chip is a vector. The output would also be a vector that should send out the data already initialized at the active clock edge, depending on the address input to the chip.
