Sure, here’s an example implementation of a 4-bit magnitude comparator using SystemVerilog:
module comparator(input logic [3:0] a, input logic [3:0] b, output logic eq, output logic gt, output logic lt);
assign eq = (a == b);
assign gt = (a > b);
assign lt = (a < b);
endmodule
In this example, the "comparator" module has two input signals, "a" and "b", which are both 4-bit vectors, and three output signals, "eq", "gt", and "lt". The "eq" output signal is high when "a" is equal to "b", the "gt" output signal is high when "a" is greater than "b", and the "lt" output signal is high when "a" is less than "b".
The use of the comparison operators "==" and ">" in SystemVerilog makes it easy to implement a magnitude comparator in a concise and readable way. The comparator module can be easily extended to handle larger bit widths by changing the size of the input vectors and the number of output signals.
