 4 Write the VHDL with select when statement for the output

4

  1. Write the VHDL with select when statement for the output of the majority circuit. The with select when statement, also known as the selected signal assignment statement, is based on the truth table for the circuit.

    The syntax for, and a detailed description of, the VHDL with select when the statement is provided in Section X.X.X, below, and in Appendix A of your textbook.

Boolean Expression:

VHDL Code (signal assignment statement):

VHDL Code (with select when statement):

A Majority Circuit outputs a logic-1 when the majority of the inputs are logic-1. Otherwise, the circuit outputs a logic-0. A 3-input majority circuit is defined by the truth table given below. | | # 0 A B C F 0 0 0 0 0 01 0 011 1 0 0 | 1 0 1 1 1 0 1 1 1 6 7 1 Table 1: 3-input Majority Function Exercises: 1. Derive a simplified Boolean expression for the output of the majority circuit. 2. Write the VHDL signal assignment statement for the output of the majority circuit. The signal assignment statement is based on the Boolean expression for the circuit. 3. Write the VHDL with select when statement for the output of the majority circuit.
