I need the VHDL file for the attached Multiplexer Circuit I

I need the VHDL file for the attached Multiplexer Circuit. I also need to know the sockets to connect it to the eSOC board in Quartus II. Thanks.

As a system, the characteristics are as follows.

If A is LOW, then the output depends on the state of switches 0 to 3.

If 3,2,1,0 = “0000” then the output display = 0 = “1111110”

If 3,2,1,0 = “0001” then the output display = 1 = “0110000”

And so on.

If A is HIGH, then the output depends on the state of switches 4 to 7.

Solution

A is low,

If A is LOW, then the output depends on the state of switches 0 to 3.

If 3,2,1,0 = “0000” then the output display = 0 = “1111110”

If 3,2,1,0 = “0001” then the output display = 1 = “0110000”

And so on.

If A is HIGH, then the output depends on the state of switches 4 to 7.

A is high, output shows 1

A is low output is 0
