Hi everyone,
I have a Simulinik model that uses Cos block (a fix point tool). Previously it runs fine but it can't run anymore, with following error:
requested use of data type 'sfix32_En16'. Use of this data type requires a fixed-point license, but license checkout failed. To use this model without a fixed-point license, select "Fixed-Point Tool" under "Fixed-Point" from the model's Tools 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.
Any suggestion?

That sounds like a problem with checking out a license. Without knowing which license you use it is hard to suggest, but MathWorks installation support or yyou IT likely will be able to help.
