that the behavior is to pare down any existing selection by removing
any parts of it that do not intersect the layer specified on the
command line. This is generally more useful than the previous
method, as the intended purpose is to intersect a number of layers
against one (e.g., all transistors intersecting deep nwell).
addition to "-list", where the list of layers returned is more
like the (recently extended) non-listing method where each type
is followed by a list of cell names in which that type is found
(within the selection area).
that contain the selected paint. Previously, all cells inside the
area of the selection box would be printed, which is completely
wrong, and can lead unexpectedly to thousands of cell instance
names being printed out.
it as a single value "flags" (unsigned char) with meaningful flag
names. Added new option "-fail" to the load command to allow
magic to fail on loading a cell that does not have a corresponding
file rather than the default action of creating a new cell. Added
a flag for the "-quiet" option so that behavior on "-fail" can be
done quietly.
to allow a cell to be flushed with dereferencing (i.e., discard any file
path attached to the cell, and use the search paths to find the cell when
it is reloaded).
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.
were made where contacts are placed when shifting up on metal
layer but not made for the reverse case. Also corrected one
inconsistency with non-minimum width wires.
centering wires on grid lines when using a snap grid) so that
the wire width is maintained when switching from one layer to
another, when the wire width is larger than the minimum for the
route layer.
