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.

    I'm not sure how we came back around to this question. At the beginning of this post, I descrbed how you can setup an object selection filter. In the example I described how to check for a property on an instance to determine if it is selectable or not. If all you are missing is the bindkey, you can set it up this way:

     hiSetBindKey("Layout" "<Key>F7" "css()~>myFixedProperty=t") ;This will lock the object
     hiSetBindKey("Layout" "shift<Key>F7" "css()~>myFixedProperty=nil") ;This will unlock the object

    This assumes you use the functions defined at the beginning of the post. Also, the above could be used to lock shapes, but if you want to limit to instances, you'll need to check the object type:

     hiSetBindKey("Layout" "<Key>F7" "when(css()~>objType=="inst" css()~>myFixedProperty=t)") ;This will lock the selected instance
