Running DRC on a file with multiple top cells

juliaya

Hello all,

I'm trying to write a very simple DRC check and run it in batch mode.
It is working just fine , but for cases that my gds file have multiple top cells in it.
Actually I know the name of the top cell I need to check, and tried to select it writing :

source($gds_file).select($top_cell)
cell($top_cell)

, but the DRC continues to fail with error message:
klayout -b -rd gds_file=my.gds -rd top_cell=mytop -r try.drc
*** ERROR: In try.drc: The layout has multiple top cells in Layout::top_cell
*** ERROR: The layout has multiple top cells in Layout::top_cell in MacroInterpreter::execute
try.drc:1:in `execute_drc'
:/built-in-macros/drc_interpreters.lym:94:in `execute'

It must be something very stupid I'm doing wrong, but still I could not figure out what is wrong.

Thanks in advance,
Yulia

Hi Yulia,

the solution is actually very simple:

source($gds_file, $top_cell)

should do the job.
