ModelicaSpec

On Page 97, section 8.3.7 there are explainations on asset funtion. Maybe it might help you.

I have seen it. I want to print an error when these two parameter are false or true both of them at the same time.

I try to use an auxiliary boolean parameter n :

parameter Boolean n = false;

equation

if Step ==false and Ramp == false then
n = true;
elseif Step == true and Ramp ==true then
n = true;
else
n = false;
end if;

assert(n,"message",level = AssertionLevel.error)


But it still not working. Can you help me?

you can compare both parameters directly as the condition of assertion.

assert is triggered (e.g. the simulation is stopped) when the condition is not fulfilled(i.e. condition = false). In your case it should be

mode foo

  parameter Boolean p1 = true;

  parameter Boolean p2 = true;

  Boolean n;

equation

  if p1 == p2 then

    n = false;

  else

    n = true;

  end if;

  assert(n,"Assertion Test" ,level = AssertionLevel.error);

  //or

  // assert(p1<>p2,"p1 can not be identical to p2", level = AssertionLevel.error); // this will also abort the simulation like above assertion

end foo;

so when both p1 and p2 have the same value, n would be false and thus the assertion triggered.

hope it helps you a little bit to understand OM

Problem solved! Thanks you so much!
