cloning group

howardhaoracle

Hi.

How can I clone a group in layout?

I can create instance and place them at several places in layout. When I modify one instance, all other identical instances will change at the same time.. But I dont want to create instance, I'd like to use group instead and clone it .. 

 Thanks for your help

    Howard,

    If using VLS XL you can do a "synchronous" copy (as an alternative to a synchronous clone) - this can create a copy of the original transistors and interconnect, and put both the original and copy into figGroups which are treated as synchronous - so an edit to one also edits the other.

    Regards,

    Andrew.

    Hi Howard,

    while in copy command type on F3 to get the copy options form.

    In the lower section of this form is the button for create synchronous copy.
