I am trying to make a Pattern Detector who will detect the pattern 1101001 by using Moore FSM. My FSM is working fine but when i am trying to generate a HDL code,I am getting many errors and unable to rectify them. Please help me to generate Verilog/VHDL Code. I am unable to do it. I will be very thankful to you,please help me ?

Can you try the attached model again? As you can see I do not see such error.

I got the mistake , I was generating the HDL code for whole system,while i have to do it for subsystem only.
Now i did it for subsystem, and i able to generate it successfully . Thank you so much sir, I have no words to say thanks to you. Thank you again.

HDLCoder does not support Stateflow chart configured with floating-point types.
Based on your application you do not need support for floating-point types for this pattern detection example. Changing input types to boolean and changing output assignment to logical true/false for OV variable you can trivially transform the moore chart model to use efficient logic types and generate a hardware friendly state machine.
With these changes I was able to generate code for the model.

If you have trouble loading the model try
web(fullfile(docroot, 'simulink/gui/simulink-preferences-model-file-pane.html'))
slprivate('showprefs') and uncheck "Do not load models created with a newer version of Simulink"
or run this command
>>set_param(0, 'ErrorIfLoadShadowedModel', 'off')

Thank you for trying to help me,but sir i am unable to load the model, I unchecked - "Do not load models created with a newer version of Simulink"
But getting 2 warnings and a blank modal is loaded.
Can you please save it in previous version of MATLAB 2019a,It will be a great help for me. I am too much worried about it,Please kindly help me.
