Implement a 4-input OR gate using SystemVerilog.

Sure, here’s an example implementation of a 4-input OR gate using SystemVerilog:

module or_gate(input logic [3:0] a, output logic out);
    assign out = |a;
endmodule

In this example, the “or_gate” module has four input signals, “a[3:0]”, and one output signal, “out”. The “|” operator is used to perform a bitwise OR operation on the input signals, producing the output signal “out”.

This implementation of a 4-input OR gate is simple and concise, using only a single line of code. The use of the “|” operator to perform a bitwise OR operation on the input signals is a common technique in SystemVerilog for implementing OR gates with multiple inputs.
