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.

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')
