VERSION
Merged recent changes from master back into bplane, as the efficiency of
bplane for doing extraction on large layouts is unquestionably better.
Fixed the implementation of DBMoveCell() for bplane. Corrected an error
in the bplane version of dbScaleCell() that enumerates cell uses but
does not free the list.
coordinate system origin to the specified (current) location.
This is a much more efficient method than selecting everything in
a layout and moving it, especially for very large layouts where
selection and moving becomes prohibitive.

which had been changed a few months back to remove the individual
cell count and only list the top level cell. The behavior has been
changed a bit so that "list" returns values for the top level cell
only, but "listall" returns a complete list. "drc list count total"
gives the DRC count for the top cell, but "drc listall count total"
gives the DRC count for everything (probably not very useful).
Also: Implemented a behavior by request to automatically removed
the (UNNAMED) cell whenever a new cell is loaded and the (UNNAMED)
cell has not been modified.
to be investigated here. I am no longer sure why I removed the
cell search from DRC count, but it appears that the cell search is
non-functional, and it should be determined why. There is no
particular reason not to have a DRC count search. It could be
implemented such that "list" vs. "listall" counts the top cell vs.
all cells. First it must be determined why there are no subcell
counts.
only at the time of running the command "load". But cells are generally
loaded only on an as-needed basis, so the dereferencing option must be
saved as a flag in the cell and honored whenever its subcells are expanded
or otherwise read at a later time.
categorized by error type and scrolled through conveniently. However,
it needs work dealing with finding the actual error bounds. The
"DRC count" counts tiles, which is tile-plane-geometry-specific, and
"DRC listall why" fractures errors both over tiles and over the square
areas that the interactive DRC splits the layout into, for performance.
The DRC error plane needs to be changed to hold different types for
each error class, so that errors can be scanned by boundary instead of
by tile (work to be done).
rid of redundant port entries in subcircuits. There is still an outstanding
issue as to whether nodes and connections need to be recursively iterated
to the hierarchy bottom. The current fix corrected the test case. Also,
added a "-dereference" option to the "load" command to revert to the
original behavior of using only search paths from "addpath" when searching
for files to load.
(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.
routine was erasing and redrawing in one step, which ignored the
possibility of having to erase from one window and redraw in
another if the cursor moved focus from one window to another.
This led to crosshairs being improperly drawn and erased when
multiple windows were present, if the windows had different cells
loaded.
This correction allows a full path to be passed for the cellname
and will (correctly) break the path into cell name and path
components (previously was naming the cell with the full path).
To avoid name conflicts, the cell name gets modified if the path
cannot be resolved against an existing cell of the same name.
that are longer than the formerly-fixed array size 256. This
conflicted with the recent addition of holding path data in
properties, where the path coordinates can be significantly
longer than the fixed array size. Same change as made to magic
version 8.1.
from "gds polygon subcell". Previously both polygons and paths
were put into subcells named polygonXXXXX (substitute numbers
for XXXXX). Now polygons go into cells named polygonXXXXX and
paths go into cells named pathXXXXX. This makes it easier to
keep track of the original path. NOTE: The path centerline
should be kept as a cell property in this case, and the path
options like endcap style can also be held as properties. The
polygon boundary should be treated similarly.
