How to keep some instances un-movable (fixed position) in virtuso

 Dear All,

 I think one definitely would have faced this problem while integratiing many instances/blocks in the top level layout in Virtuso.

The problem I am facing is as follows:-

In the top level of the layout, I have to integrate many instances of layout blocks.

While connecting two blocks ( these two blocks are inside a bigger blocks (like PAD array) or may be crossing over another small block) , some how some  the other blocksare getting moved.

Ideally like to keep the positions of other instances ( let's say A, B, C) fixed, while editing the desired instances ( let's say E,F)  as movable.

I tried in LSW. I dehighlighted the 'inst'. In that process, all the instances are becoming un-movable. Even if you bring a VIA , you can't move it around.

Could anybody please tell what I should do thing smoothly.

Kind Regards,

     Dear Andrew,

    Thanks a lot for your reply.

    I like to do some modification to your skill code.

    But the "SKILL" is a new language to me.

    I want to know the meaning of each standard function present in thye code.

    I went through  "Cadence Analog Design Environment SKILL Language Reference", but I could not find the many functions present in your code.

    Could you please point to some document/source from where I can get the meaning of all the STANDARD functions you have written in the code.

    Kind Regards,
