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
DataTypeMode: Fixed-point: binary point scaling
Signedness: Unsigned
WordLength: 14
FractionLength: 14
>> a.range
ans =
0 0.999938964843750
DataTypeMode: Fixed-point: binary point scaling
Signedness: Unsigned
WordLength: 14
FractionLength: 14
