Can I use 'fixdt' data type without having Fixed point license?

I am trying to use 'fixdt' data type in my model, but it throws an error. So can't I use 'fixdt' data type without having 'Fixed Point' license? or is there any other process to use it

Can you share the error please?

'test_/Constant2' specifies a data type of 'sfix16_En12'. Use of this data type requires a Fixed-Point Designer license, but license checkout failed.

[Andreas Goser]

So then my answer is while you could use 'fixdt' in some situations without the Fixed-Point Designer license, you cannot do it using this data type

[Walter Roberson]

If I recall correctly, the fixed point types you can use without a license are equivalent to signed and unsigned integers of particular length, such as uint32, except that you might perhaps be able to specify different overflow behavior (I have not checked in detail).

Thanks Andreas and Walter. Though I am able to select the fixdt data type from the drop down,but while simulation it throws this particular error. Is there any other method to customize signal data type, when I know about the precision of my signal??
