Designing robust FSMs for sequence detection, traffic light controllers with pedestrian inputs, and prioritized interrupt controllers. Design Flow & Optimization Mastering advanced design requires navigating a structured VLSI design flow assign bvalid = (w_state == RESP)

// ALU inside execute wire [31:0] alu_out = (opcode == ADD) ? ID_EX_rs1 + ID_EX_rs2 : ...;

// Fixed priority on rotated requests (LSB has highest) assign priority_grant = priority_req & ~(priority_req - 1);
