Hi all,

I have updated the ruby script. The Klayout API has some interesting capabilities that might allow us to perform all the differenciate separation and shifts to the fill pattern.

I think the description of each dummy layer requirement is ready (image1) but the functions I've made to "compile" the tiling processor are not, it still fails:
• Distance to the layers is not handled correctly. (line 460)
• row_step and column_step makes the code to crash. (line 350-351)
I've added comments to some functions and a (incomplete) description of klayout concepts and drc rules.

Acording to latest DRC evaluation (Thanks <@U035UNMLDJS>) LTC2 only has COMP and POLY density errors. (I'll ignore realiability IO errors).

I think is a good idea to send this to CMC and verify if placement works, of it requires the shifting while placing cells of the same dummy layer

<@U03B029DKU5> You mean COMP, POLY2, Nwell, LVPWEL, Dulgate are used to generate Dummy COMP and there are only COMP and POLY density error, right?
and for Dummy Metal, script works well.
