when I building a simlink project with matlab2019a, The report prompts the following errors

The following block contains an S-Function that does not conform to Code Reuse restrictions. The S-Function block (a) should have a TLC implementation and (b) should set the option 'SS_OPTION_WORKS_WITH_CODE_REUSE'. [testmodel2/out_OutSignalCondition_lib/Init_PWM/fcn_PWMPEEPmax_uP2/fpga_interface]

You need to add ssSetOptions in mdlInitializeSizes(SimStruct *S) function in your C S function as following.

    ssSetOptions(S,
                 SS_OPTION_WORKS_WITH_CODE_REUSE |
                 SS_OPTION_EXCEPTION_FREE_CODE |
                 SS_OPTION_USE_TLC_WITH_ACCELERATOR);
