Since Verilog does not have user-defined types, we are restricted to arrays of built-in Verilog types like nets, regs, and other Verilog variable types. Each array dimension is declared by having the min and max indices in square brackets. Bit slicing is a technique for constructing a processor from modules of processors of smaller bit width, for the purpose of increasing the word length; in theory to make an arbitrary n-bit central processing unit (CPU). Each of these component modules processes one bit field or "slice" of an operand. The grouped processing components would then have the capability to process the chosen full word-length of a given software design. green tea with milk recipe
