what do you mean by virtual interface? like a vlan interface on a trunk for instance? HSRP?

Just imagine interface gi 0/6 have one ip address 10.100.0.5.We need to
create a virtual ip address for that interface for nating with that ip.


By default all ASA 5555-X interfaces are routed (assuming the overall firewall mode is routed - the most common mode by far).

 

So, for a given interface, you just assign a nameif and an IP address in config-if command mode.

If you have any document of configuration!please share to me?

If you are talking about vlan interface than here is an example:
interface YOUR_INTERFACEHERE.VIRTUALNUMBER
description << BLABLA >>
vlan 1111
nameif BLABLA
security-level 0
ip address 10.1.1.1 255.255.255.0

so if your range is for instance 10.100.0../24 and you want to add a 'virtual ip" say 10.100.0.10. then you will need to add a NAT 10.100.0.10 to whatever on your Firewall. it that simple

Is there is any option there in asdm for configuring virtual ip ?

Please see the second link in my earlier reply. It takes you straight to the ASDM interface configuration section.
