I have a simulink model as follows

As you can see the data output is in the form fixed fixdt(1,14,12). Can anyone help me convert the output to fixdt(1,14,13)? what block do i have to use to do that? This is my model

Please consider using fixed point designer to analyze ranges and use better fixed point types in the blocks.

Found few incorrect constant types. For example you had a constant block where '1' cannot be represented with the output type set on the block.

>> a = fi(0, 0,14,14)
a = 
     0

            WordLength: 14

>> a.range
ans =
