Question

Experiment Description: Write a Verilog module for the 4256ZE Development Board that displays four different character sequences on the four 7-segment LED displays, as indicated in the table below. Two control signals (entered on DIP1 and DIPO) will be used to specify the mode of operation, as follows (if the display mode is changed mid-sequence, the newly-selected sequence should start at its beginning, with a leading blank) DIPİ DIPO | Function The selected sequence should scroll across the four 7-segment displays (DIS4..DIS1) from right to left, i.e., the first character of the sequence should initially appear on the right-most display, then shift left one position as the next character appears on the right-most display, etc. The sequence generator should be clocked by the internal oscillator divided by two. Pre-lab Step (1): On a separate sheet, draw a state transition diagram that specifies the behavior of the scrolling display either a Mealy or a Moore model may be utilized. Note that a common "leading blank" can be shared by all four sequences.
IGNORE FIRST PART. JUST DO THE PRELAB STEP 1 PART PLEASE.
