以下是单稳态电路的RTL级Verilog HDL代码和电路结构图:
```verilog
module monostable_circuit(input clk, input rst, input trigger, output reg output);
// internal state variable
reg [2:0] state;
// define state values
parameter IDLE = 3'b000;
parameter WAITING = 3'b001;
parameter OUTPUT_ON = 3'b010;
// define delay count value
parameter DELAY_COUNT = 8;
// output default value
assign output = 0;
always @(posedge clk, negedge rst) begin
if (!rst) begin
state <= IDLE;
end else begin
case (state)
IDLE: begin
if (trigger == 1) begin
state <= WAITING;
end
end
WAITING: begin
if (trigger == 0) begin
state <= OUTPUT_ON;
#DELAY_COUNT state <= IDLE;
end
end
OUTPUT_ON: begin
state <= IDLE;
end
endcase
end
end
// set output to 1 during OUTPUT_ON state
always @(state) begin
if (state == OUTPUT_ON) begin
output <= 1;
end else begin
output <= 0;
end
end
endmodule
```
