If you are using Virtuoso layout editor, then just type on F3 key, and you
will get the options of any command you execute. For the copy command,
there are the possibilities to make the "mirror" in X or Y direction, by
clicking "sideways" or "Upside Down" in the Copy options menu.
You can also configure by default to have the menu options prompted each
time you start a command :
CIW -> Options -> User Preferences :
Options Displayed When Commands Start : *
Hope this helps.

If I have flatten the layout called from the instance, how could I mirror
copy it?
Could anyone teach me that how could I mirror copy of the Cadence layout
in the layout drawing? Actaully, I know how to mirror it when calling it
from the instance. Sometimes, I needed to modify it after flatten.
Therefore, how could I mirror copy the layout which has already the
flatten.

When flattening an instance you loose the selection of the objects that were
inside. Then you are right -- we cannot make any move or rotation or
mirroring.
One way is to first flatten the layout in an empty space, and then
select the objects (polygons, and rectangles, etc..), make the mirroring,
and move those objects on the desired location.
The other way is to first make the mirroring and then make the flattening.
Another way is to make a copy of the cell with the necessary mirroring, then
instantiate it and modify the content with the "Edit in Place" command.
(The modifications will affect only the copy of the cell, not the original).

After you hit the "c" bindkey (or the "Copy" menu button), and before you
click for the destination, press the F3 key. This is the standard options
button for almost all commands. In copy ("c") and move ("e") commands, the
options form offers mirror and rotate selections. Select your option, hide
the form, and proceed.
