Design a 4-bit up/down counter which displays its output on the
the 7-led segment using the decoder used in Lab 2.
In this lab, you will design a 4-bit up/down counter which
displays its output on the 7-segment LED using the decoder that you
designed in Lab 2.
The 4-bit up/down counter module has 4 inputs, Clk_1Hz, Reset,
Pause, and Up; and a 4-bit output Count. If Reset is 1, the counter
should reset its count value to zero (0000)....
