关于 verilogout_no tri和 verilogout_show_unconnected_pins 不起作用

522526tl

设置了 set verilogout_no_tri true 然后写了一个简单的 三态门代码：module test (clk,en,din,dout);
  input clk,en,din;
  output dout;
  reg dout;
  always@(posedge clk)
    begin
        if(en)

  dout<=din;

else

  dout<=1'bz;
end
endmodule


为什么还是会有警告呢，这个命令没起作用啊
Warning: In design 'test', input pin 'clear' of leaf cell 'dout_tri_enable_reg' is not connected to any net.  Logic 0 assumed. (LINT-0)
Warning: In design 'test', input pin 'preset' of leaf cell 'dout_tri_enable_reg' is not connected to any net.  Logic 0 assumed. (LINT-0)
Warning: In design 'test', input pin 'data_in' of leaf cell 'dout_tri_enable_reg' is not connected to any net.  Logic 0 assumed. (LINT-0)


类似还有 set verilogout_show_unconnected_pins true
和 set_fix_multiple_port_nets -all -buffer_constants
这几个命令都起不到作用

SKILLER

什么原因？
