I got the following error while executing the simulink model;

The sample time 1e-06 of 'HDmodel/adc1/Add' at input port 1 is different from the sample time 2e-05 of 'HDmodel/adc1/Data Type Conversion' at output port 1. Consider inserting a Rate Transition block between the two ports. Alternatively, you can control the diagnostic action for unspecified rate transitions by changing the option "Multitask (or Single task) rate transition" on the Sample Time Diagnostics pane of the Configuration Parameters dialog box.
