the code must be in Verilog HDL Language.

Problem 1: Sequential Bidirectional Decade (mod-10) Counter A. Design a bidirectional mod-M Counter that can count up from 0 to 9 and count down from 9 to 0. The circuit should have the following inputs . reset: to reset the counter countUp specifies whether to count up or down B. Derive the test bench and use functional simulation to verify the operation of the code. C. Design a testing circuit that displays the count on the seven segment LED display and derive the code.
