How can a saturation block emulate the option "Saturate on integer overflow" of a block?

Hi,
In my models I cannot use the option "Saturate on integer overflow" due to incompatibility with MISRA rules. I need to use a saturation block instead and I was wondering which are the correct values of upper and lower limits in order to obtain the same behaviour as if I had the option checked.
Thanks in advance, Patricia

Hi Patricia,
You can use the MATLAB functions intmin and intmax to get the saturation values. For example
>> intmin('int16')
ans =
-32768
>> intmax('int16')
ans =
32767
I hope this helps!
Owen
