How to lock the cell placement

bharath2k4er

Hi, 

can someone help in locking the placement of the Instance (should not be able to move the instance once i lock the position) in the virtuoso layout editor using skill..

It is equvivalent to this command SET_OBJECT_FIXED_EDIT(GET_SELECTION) 1 (1 means postion fixed, 0 means postion is notfixed).This command is available in the IC compiler (ICC tool). 

 

Thanks for your support,

Bharath.

    My mistake. I defined the procedure after the call to the procedure. Simply move the call to leRegUserObjectSelectionFilter after the definition of the procedure.

    If you want to lock all of the instances for the set of code defined above, do the following:

    procedure(lockAllInsts(@optional (cv geGetEditCellView()))
        foreach(inst cv~>instances
            inst~>myFixedProperty = t
        )
    )

    Call this command to lock all the instances from being selected. Since this approach doesn't allow instances to be selected, there won't be an easy way to print a message indicating that the position is locked. You would have to create wrappers to the move or stretch commands, but this then becomes messy and difficult. I have tried this and actually opened the ticket with Cadence to get this selection filter. This filter made things much easier.

    If you want to unlock the instance, you'll need to change the "myFixedProperty" to nil. The following routine unlocks the selected instances.

    procedure(unlockInsts(@optional (insts setof(x selectedSet() x~>objType=="inst")))
        foreach(inst insts
            inst~>myFixedProperty = nil
        )
    )

    I did not intend this code I posted to do all you need it to do. It should serve as an example for you to work from. Take this time to get familiar with the Skill documentation, it is very good.
