Assert

Assert provides a convinient means for specifying checks on model validity within a model. The assert-expression in an assert equation should normally evaluate to true. A failed assertion, i.e. when the expression evaluates to false, should be reported back to the user in some way that is dependent on the simulation tool.

class AssertTest Real lowlimit = -5; Real highlimit = 5; Real x = 1; equation assert(x >= lowlimit and x <= highlimit, "Variable x out of limit"); end AssertTest;
class AssertTestInst AssertTest assertTest(lowlimit = -2, highlimit = 6, x = 5); end AssertTestInst;

Here the simulation of the AssertTest is shown. The variables can then be plotted below.

simulate( AssertTestInst, stopTime=5 )
plot( { assertTest.x, assertTest.highlimit, assertTest.lowlimit })
