    can we change the lib, cell & view of an instance using skill Reply

    Hi,

    Iam trying to write skill for changing the libname, cellname and viewname of an instance in layout. the flow would look something like below

    1) when u key SHIFT+ t in ur layout u get a tree form from which u select a top to bottom information of the instances in that layout.

    2) according to this information i need to create a user defined form that contains a browse button to select/change the current instance to other instances. (this is similar to invoke the library manager ) 

    3) so the final thing when set ok by selecting the libname, cellname and viewname in the user defined form the changes should be reflected on the current layout.

    i think this program would help a lot of people who work on similar kind of layouts. this can help save time in floorplanning.

    thankyou

    regards

    VAKA

    Hi VAKA,

    Can you not use the standard Tools->Remaster Instances command (IC613/IC614) or Design->Remaster Instances (IC5141) to do this? Not sure why you need SKILL...

    Or you could use the Tools->Find/Replace (IC613./IC614) or Edit->Search (IC5141) command to do it.

    Or in IC613/IC614 you could use the search assistant to find them all, and then the property assistant to change all the masters. 

    Lots of ways of doing it.

    Regards,

    Andrew.

    Andrew,

    Is there a (one-step) way to do this with symbols in Composer?

    To remaster all symbols like we can remaster all instances in Virtuoso?

    In IC5141 you could use Edit->Search->Replace and search for (say) a master, and replace that master with somethng else. When you pick master as the thing to search for, you need to specify it as libName cellName viewName (i.e. space separated on the form).

    In IC61X the form is found using Edit->Replace.

    Andrew
