Sim/circuit3

This is a combinational circuit. Read the simulation waveforms to determine what the circuit does, then implement it.

module top_module (
    input a,
    input b,
    input c,
    input d,
    output q );//
    
    //assign q = (b&d)|(b&c)|(a&d)|(a&c); // or
    //assign q = ~((~a&~b)|(~d&~c)); // or
    assign q = (a|b)&(c|d); // Fix me
