ID:13030 Reduced the following open-drain buffers that are fed by GND

CAUSE: The design contains one or more open-drain buffers that are fed by the constant GND. Essentially, the output pins that these open-drain buffers drive will always have the value GND. As a result, the Quartus Prime software replaced the fanout from the open-drain buffers to the output pins with the constant GND. For example, this situation occurs in the following Verilog design:

	module test (output out); 
	wire gnd; 
	assign gnd = 1'b0; 
	OPNDRN my_opndrn (.in(gnd), .out(out)); 
	endmodule
