WebbWhen you divide by zero it is undefined and results in a runtime error in the generated code. When you divide the minimum representable value of a signed integer by negative one, the ideal result is equal to the maximum representable value plus one (INT_MAX + 1), which is not representable. Webb23 nov. 2011 · Under menu Simulation->Configuration Parameters...->Diagnostics-> Data validity, turn on the check for "Signal"->"Inf or NaN block output".
