Asynchronous function-call Initiator

My model has a variant subsystem and in variant subsystem in add_sfcn reference model I have two subsystems, one is running at 10 ms and one is running at 50 ms and when I compile variant subsystem, I am getting error as "The function call input port 1 of model block 'Variant_Logic/Variant Model/Model1' must be driven by an asynchronous function call initiator." Can you please suggest how to fix the issue? I have attached the zip file of required models and script. Before compiling model run Variant_definition.m file.

The functon-call trigger port needs to be connected with a function-all signal, usually from a function-call generator block. Double click the function-call generator block, click Help to bring up the document, look at the examples.

Yes, The functon-call trigger port is already connected with a function-all signal, and I have generated with stateflow chart instead of function call generator. Is function call generator is an asynchronous function call initiator??

[Fangjun Jiang]

No. The Function-Call Generator block can only generate function calls on a specific rate.

[Sachin Patil]

Yes, then unfortunately that will not resolve my issue. Can you please run the attached model and check the architecture then might be you will get the clue.

appriciate the help!
