#255 Basic filler scripts for ihp-sg13g2 open PDK Pull request opened by KrzysztofHerman This PR contains basic filler scripts for the PDK. The filling process can be run from the command line using a python script:

klayout -n sg13g2 -zz -r $PDK_ROOT/$PDK/libs.tech/klayout/tech/scripts/filler.py -rd output_file=./design_filled.gds design_nofill.gds

It is mandatory to have a

sealring

in the design. In order to control metal filler densities user can modify the following scripts:

$PDK_ROOT/$PDK/libs.tech/klayout/tech/scripts/macros/sg13g2_filler_Metal.lym  
$PDK_ROOT/$PDK/libs.tech/klayout/tech/scripts/macros/sg13g2_filler_TopMetal.lym

where the

width

,

length

and also the

distance

between the filler cells can be altered. Please respect the DRC rules related to the sizes and separation of the filler cells (sections

5.18

and

5.23

of the

SG13G2_Layout_Rules_os.pdf

document). While running

minimal DRC

in klayout one can expect

AFil.g2

,

M1-5Fil.h

errors related to the area outside the design, where the densities are calculated. The errors can be waived. Special thanks to

Daniel Schultz

for providing the scripts. IHP-GmbH/IHP-Open-PDK ✅ All checks have passed 1/1 successful checks
