It's not clear for me

Original contents of block error as : Saturation occurred. This originated from ' here contain path of block means Path representing Lookup table ' .

It does sometime happenned on my model too.

What i did to 'solve'the problem is by setting the Lookup method to Interpolation - Extrapolation instead of Interpolation - End values.

And then connecting Saturation block after the Look-up table to saturate the values.

HTH, Ilham

Thanks for suggestion. I,m using Lookup method _ to _Use Input Nearest. When i used other Lookup method, there is no issue. I know that Use Input Nearest method removed from R2012b. but i think every version show backward compactiblity. i want to know that because of this error occured, or something else is reason.

For my lookup table data type for first breakpoint is fixdt(0,16,0.1,0) and second fixdt(0,16,2^-9,0) and output data type is unit16. I had selected the interpolation method to "Linear" and Extrapolation method to "clip". But still i am getting the same error.
