How to implement soft reset or functional level reset in vr_ad register model?

Hi all,

In my project in the register model i have some fields which are sticky i.e. they are not effected by reset.For such fields how to implement in vr_ad? If it is possible, is there any chance to implement dircetly from the IPxact script(With the help of verdor defined extensions)?

 Please help me in this regard.

Thanks in advance,
