What is the current way to define several LEF files with a pattern in the config.json? I am trying this: "CELLS_DIR": "dir::../../cells", "EXTRA_LEFS": ["ref::$CELLS_DIR/lef/*.lef"], "EXTRA_GDS_FILES": ["ref::$CELLS_DIR/gds/*.gds"], but they are not merged. Can I debug the resulting EXTRA_LEFS ?

@Philipp Gühring I believe the expansion of

config.json

is in

runs/<tag>/config.tcl

. Looks like you can check the

foo::

expansions there.
