forces all ports in a cell to be reordered in alphabetical order,
which ensures that the output of "extract" is always the same
(apart from coupling capacitance, which still ends up in randomized
order due to the use of hashing based on memory address followed
by iterating through the hash table).
could cause serious errors on systems that do not auto-zero allocated
memory. Also: Fixed an error introduced by a recent commit to allocate
character memory for efReadLine() which frees the memory before reading
a .res.ext file, causing a crash when using "ext2spice" with the
"extresist on" option.
optional name field to the "substrate" line in the extract section
of the techfile. This is the default name of the substrate if not
connected to anything labeled. It may use a Tcl variable (preferred).
(2) Added command option "instance orientation [-def]" that returns
the orientation of the named or selected instance. The -def option
returns the orientation using DEF naming convention; otherwise, the
naming used with "getcell" is generated.
argument as a pointer but also set the same variable to the
return value. This is ambiguous, because the behavior depends on
whether the value being set upon return is the original value or
the reallocated value. The result is system-dependent behavior.
SPICE subcircuit definitions from a netlist file and apply the port
order in the netlist to the port labels in the corresponding cell
or cells in the magic database. Also: Corrected an error in the
bloat-all code introduced in a recent commit that can cause a
segfault.

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.

Merged recent changes from master branch into bplane branch. Testing the
bplane implementation which has about a 5x improvement in extraction times
for large layouts, which is significant enough to move ahead with the bplane
implementation; however, the bplane implementation has not been thoroughly
vetted yet, so it will remain a branch until such time that it has been
validated.

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.
down in the hierarchy when selecting a region or net, but with a
(hopefully very useful) twist: To avoid the problem of ambiguous
labels in subcells, the subcell name hierarchy is generated in
the same way as is done when flattening a cell, with the instance
name prepended. For example, when selecting a net in a standard
cell design, a terminal would highlight the name "OR2X1_1/B"
instead of just "B".
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.
simple FET device in extresist. Also: Extended the bloat-all CIF operator
again, allowing the trigger layer for the bloat operation to include both
CIF layers and magic layers (previously only magic layers were supported).
This extension is possible due to the previous extension allowing the
trigger layer and bloating layers to be on separate planes. This operator
extension is useful for tagging geometry that is in the proximity of, but
not overlapping, geometry on another plane.

centering wires on grid lines when using a snap grid) so that
the wire width is maintained when switching from one layer to

(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.

Attempts to modify ports in non-edit cells result in an error
message that is more helpful than the previous "Exactly one label
must be present..." text.
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.
since the edit box was undefined in the code, potentially this
fixes any number of random problems that might be seen with the
"port" command. Also: Modified the cell bounding box recalculation
so that it does not continually update a parent cell on every
addition of a child cell but only once for each child cell found.
This greatly reduces the time for GDS file input in the case of
large arrays of cells.
function that was available in versions 7.1 and earlier that
allows the use of the command "erase errors" to remove DRC error
paint (only when the DRC checker is off, of course).
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.
a port so that repeated uses of "apply" won't fail because the
port number is already used. Corrected the "port remove" command,
which didn't work, and corrected the script to do "port exists"
before "port index" so that the latter won't complain if the label
is not a port. Same changes made to magic-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.
avoid the problem where subcells violate DRC themselves but do
not violate DRC in the context of the parent (i.e., the parent
adds metal to avoid minimum area error), DRC errors in subcells
are neither counted nor displayed, but they remain present in
the subcell database. The DRC check enumerates all subcell
errors as mandatory check areas in DRCFindInteractions(), so
that those areas are always counted with the interaction areas.
Previously, if a subcell violated a DRC rule by itself, that
error would be counted and displayed in the parent even if the
parent had paint causing the error to no longer exist.
