Toggling boolean value depending on condition

Toggling boolean value depending on condition

Jan-17-17 10:58:36

I am trying to toggle a boolean variable depending on some condition as per the following code.

Code:

model boolean_logic_try

  

  Boolean dio_out;

  Boolean dio_out1;

 

  equation

  if (mod(time,0.01) == 0.0) then

    dio_out1 = not dio_out;

  else

    dio_out1 = dio_out;

  end if;

  dio_out = dio_out1;

  

end boolean_logic_try;

But, I am getting the following error in compilation stage as follows.

Code:

boolean_logic_try_02nls.c: In function 'initializeStaticDataNLS2':

boolean_logic_try_02nls.c:35:84: error: 'BOOLEAN_ATTRIBUTE {aka struct BOOLEAN_ATTRIBUTE}' has no member named 'nominal'

Compilation process failed. Exited with code 2.

Is there a problem with my logic or something else?
Any help will be greatly appreciated. Thanks in advance.

Yes, you have created an algebraic loop saying basically dio_out = not dio_out, which cannot be solved. Make dio_out a discrete variable:

Code:

when sample(0, 0.01) then

  dio_out = not pre(dio_out);

end when;
