required fixed-point license라고 나옵니다.

엊그제까지 잘 되던 simulink 파일이 fixed-point license가 없다고 동작하지 않습니다.

matlab 라이센스를 직접 등록해서 사용하기에 이런 문제가 발생하는 것이 의아해서 문의드립니다.

아래는 오류의 전문입니다.

'Original_onboard_matlab/Signal_Mapping_CMDs/Data Type Conversion' requested use of data type 'sfix16_En14'. Use of this data type requires the Fixed-Point Designer license, but license checkout failed. To use this model without a fixed-point license, select "Fixed-Point Tool" from the model's Analysis menu. Select the root model in Model Hierarchy. Set "Fixed-point instrumentation mode" to be "Force off", "Data type override" to be "Double" and "Data type override applies to" to be "All numeric types". This replaces most uses of fixed-point data types with floating-point doubles. In rare cases, a few attempts to use restricted data types may still exist. Reconfiguring to use floating-point types and/or inserting Typecasts is necessary in these cases.
