Hello all,

I have a floating point Simulink model that I want to compare its performance to a fixed-point counterpart so I want to change the model to fixed point but I dont`t know how. The blocks need data type changes and I need to specifiy integer and fraction bit sizes. I know Simulink proposes data types but I don`t know how to get to that stage. Do I need to place data recorders everywhere and something like that? Please help..
