discovered that not all LEF/DEF rectangle coordinates are in
canonical order. Took the opportunity to update the LefError()
routine with an additional argument so that it can separate
errors, warnings, and informational messages, and will correctly
state whether the output is for a LEF or DEF read operation.
(once corrected in an experimental branch but never merged). This
avoids changing the actual bounding box of the cell to match the
LEF bounding box, but defines a property instead and uses that
property for certain functions such as displaying the bounding box
outline or selecting the cell. This avoids certain related errors
such as the failure to extract connections to areas outside of the
fixed bounding box.
label in a DEF file is on a layer that has not been properly
mapped to a magic layer. This would apply a negative index to
a TileType bitmask and crash the program. Also: Changed the
style and colormap slightly to make the via2 and via4 styles
more visible.
development had been halted since it was first created back in April.
Version 8.2 is now the official development version, with the first
development push to create a Cairo graphics interface.
