Write an HDL behavioral description of a four-input priority encoder. Use a four-bit vector for the D inputs and an always block with if–else statements. Assume that input D [3] has the highest priority (see Problem 4.36).

Reference: Problem 4.36

Write the HDL gate-level description of the priority encoder circuit shown in Fig. 4.23 . (HDL—see Problem 4.45.)
