truncation of data at the output for arithmetic operations

In fixed point environment truncation of output data is happenening for the arith blocks when we use "Inherit: via back propagation " as output datatype. The output is taking datatype of input sometimes.

if we keep "Inherit: vai internal rule" option the datatype is going to some data types like ufix40,ufix24 etc.

Our requirement is it should take ufix8,ufix16,ufix32,sfix8,sfix16,sfix32 dataypes. other datatypes is creating huge code while generating autocode.

This scenario i faced inside library blocks where we have to choose only one options which cannot be modified by the users.(using of local variable with resolving as the output whose resolution can be set as we want wont work since it is library.)

Can you help me on this ?
