Hi Venkat,
add required="true" in your markup for input field.

<aura:component >
    <aura:attribute name="EmpName" type="String" default='' />
    <lightning:input label="Employee Name" value="{!v.EmpName}" required="true"/>
</aura:component>

Thanks for your quick reply Puspendra.

Your Answer work for <lightning:input >,
but I am looking for <lightning:inputField  >,  in <lightning:inputField  > "required" attribute not supporting ,so If you have any customized validation code for <lightning:inputField  > Plesae let me know.

I am assuming you are creating some record in salesforce object. And before saving you need to make sure the input value of some fields are not empty. Here is a javascript controller that checks if the Subject field on a case input record is empty of not. 

        var caseRec = component.get("v.caseRec");
        if($A.util.isEmpty(caseRec.Subject) || $A.util.isUndefined(caseRec.Subject)){
            alert('Subject is Required');
            return; 
        }

Hi Venket,

You are not able to use validity on lightning:inputField because the attribute is not supported on this component, instead its an attribute for lighting:input.
For validating lightning:inputField , you can refer to 
https://salesforce.stackexchange.com/questions/213804/how-can-one-validate-recordeditform-fields-before-submitting-them-to-the-platf/213905#213905  link provides a perspective as how you can validate values entered on the component.

lightning:inputField DOES accept 'required' 
<lightning:inputfield fieldName="Name" required="true"/>

It puts a red asterisk against the field.

You can validate either on the field changing, or on submission of the record. 
<lightning:recordEditForm  objectApiName="myObject__c" 
                              onsubmit="{!c.handleSubmit}"
                              onsuccess="{!c.handleSuccess}"
                                      aura:id="recordEditForm" > 

<lightning:inputfield fieldName="Name" required="true"  onchange="{!c.handleChangeName}"/>

handleSubmit: function(component, event, helper) {
        event.preventDefault();       // stop the form from submitting
        //do something to the input
        var fields = event.getParam('fields');
        var recName = fields.Name.toUpperCase();
        fields.Name = recName.replace(/ /g, '_');
        //submit the record
        component.find('recordEditForm').submit(fields);
    },//handleSubmit
