Raw Normal View History

Made a slight modification to the "lef write -hide" routine; previously, MASTERSLICE layers would not be added to obstruction layers made by "-hide". However, an nwell, for example, that stuck outside of a prBoundary *would* be recorded, which was inconsistent. Resolved this by allowing MASTERSLICE layers in the OBS block, but only for layers that are not a substrate type. NOTE: It may be better to just insist that a MASTERSLICE layer define an obstruction type in the "lef" section of the tech file, and treat it like routing obstructions. Alternatively, one may question whether special obstruction types are needed at all, as one could simply define an obstruction as a type without a port label.
