Proof of Concept Router for Klayout
git hub is here https://github.com/hgroller/KlayoutRouter.git


All text locations must be on an int grid location
no float's at the present time
Layout is based on Matthias si4all dummy pdk

Code consists of :
place both files below in C:/Users/your_path/KLayout/pymacros

Router.py ----- in sys.path.append("C:/Users/your_path/KLayout/pymacros") and change your_path

AstarRouter.py

testroute.gds is the test gds file with Text placements

Load Router.py in the IDE with the testroute.gds file open, the run .

In AstarRouter.py you can play with blockages by adding 1's in the maze array

Have fun, Comments welcomed.

  • Cool! Thanks a lot! :)

    Would you mind formatting the text in Markdown? I guess there are some "#" characters which make the text super large (those are taken as H1 markers).

    Thanks,

    Matthias

  • Matthias,

    I tried , let me know how the test's goes on your side
    I am in the process of getting this to work with floats, off grid etc.

  • Hi Matthias,
    I setup this package, and got some problem. I can execute "Create Array Label pins", but when I execute "Load Router", it showed "DPoint" is not find. I don't know how to fix it? Or anything went wrong ? Furthermore, how to install pdk si4all? Thank you.
