Hello all,

I am creating a simulink model in fixed-steps. All my blocks' outputs are double with one exception (altough I do not know if that is the source of the problem I will state) pre-lookup table.

When I run the Fixed Point Advisor at the check 1.2 Verify update diagram status I get the error:

--
Failed
Cannot retrieve port data types.
Parameter must be a string.
Model update failed. Parameter must be a string.
--


When I remove the pre-lookup table the problem is solved.

What is the nature of this problem? How can I solve it with a pre-lookup block existing in the model?
