Help Needed for Quickplace using Skill/Script

 Hi Guys

I am not showing off but I have completed a Skill script that would help in quickly placing huge amount of components within a minute

and also will help in tracking their parents w.r.to it's page / parent hierarchy etc...

I have attached the presentation I did to my company, due to the amount of work involved , the time I spent as well some confidentiallity issues I can't post the entire code.

But this post might give some Ideas how it is done and what else is possible

Here is what I do in the skill file

1. Get all the component definition

2. Identify the logical path property

3. Parse it such that you create groups of different hierarchy and Pages

4. Once you have the list of all the hierarchies create lists for individual pages and their underlying components

5. Now place them with respect to their pages/hierarchies

6. calculate the new locations 

7. For tracking their parent's assign properties on the symbol level and use the treeview interface to highlight them

I can give little bit more clues on the placement logic. search in google of 2D bin packing  

although I used a variation of this logic

Basically I pre-sorted all the components w.r.to their size (you can either use place bound or pin count clue :-)!!!) on the individual pages

then I sort all the pages within a given hierarchy w.r.to their size and sort all the hierarchies w.r.to their size

Now I start on a given point and place the first component, since I pre-sorted it I am positive that the next member in that page is either same size or smaller than the first one.

Now I place the second one and compare its extends with my pre-defined Page box if it fits I place it or i place it on the next row.

This continues so-on and so forth for pages and hierarchies

 I have attached the presentaion which will give you some ideas how it looks

 I can answer your questions and give more info on the techniques but unfortunately I won't be able to post the entire code

I appreciate the understanding of this matter

Good Luck

regards
