Is there an easy way to have magic error out if there is geometry outside the defined cell area ? Like we provide a DEF template to users (for size / pin position / ...), but seems that if the user put meta outside the area, and then write the LEF, the LEF will still ahve the size we defined in the template but will have OBS outside of it. We'd like to see that as an error.

There is a way to do this; there is a "cifoutput" operator "boundary" which is the bounding box defined by the FIXED_BBOX property boundary; this could be used to create a "cifdrc" rule that flags everything outside the FIXED_BBOX boundary as a DRC error.

Ok, will look into it, thanks.
