Why do I get this error:
Inconsistent numeric values for port 1 of 'mDesignRange/output_signal': Output value (24.774542937654335) at major time step 33 is greater than maximum (20) from 'mDesignRange/output_signal'
when I am using fxpopt for fixed-point optimization?

Accepted Answer

MathWorks Fixed Point Team
This happens when your model simulation violates your design ranges (min, max specifications). Fxpopt throws this error, as it considers design ranges to be a hard requirement for your system specification and when the simulation violates the specification, fxpopt considers your model to be in faulty state.
A quick way to test this is to turn on the signal range checking by running the following command:
sim(model, 'SignalRangeChecking', 'error')
You can either update the design ranges or investigate why the simulation violates these ranges.
