output when using the "port ... index" or "port ... name" to query
values from a specific port by name or index. The "readspice"
script has been modified to use this option to prevent unnecessary
error output from the script as it searches a layout for possible
name matches to a SPICE netlist subcircuit pin list.
extra option "-default" that allows defaults to be set for any
label property other than text or port-related properties.
Subsequently, the command "label <text>" will apply the given
defaults to the label. This allows a simpler way to create
rendered labels from the command line without remembering all of
the arguments to the extended "label" command.
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.
tech file format "version" section. This can be used to specify the
version of magic that must be used to be compatible with the tech file.
This effectively supercedes the technology version number. (2) Changed
the behavior of "make" to set the version and revision numbers on doing
"make" instead of "configure". This allows the version to update
correctly after doing a "git pull" followed by "make" without doing
"configure" in between. (3) Fixed a couple of issues that were flagged
as compile-time warnings.
Instead of a 6-character suffix generated randomly, the 6-character
suffix is generated by a hash algorithm from the device parameters.
If the cell parameters are changed, then the cell itself changes.
If the instance name was default (derived from the cell name) then
the instance name changes accordingly. The result is that there
cannot be two (auto-)generated cells with the same parameters but
with different cell names.
bounding box of the selection (somewhat unuseful, especially as the
result gets absorbed by the tag callback), and "box select", which
sets the cursor box to the bounding box of the selection (much more
useful). Also corrected the "port" command so that the command
"port make" will search only for non-port labels.
command when annotating an existing layout from a LEF database, if
there is a port in the layout that is shadowed by a label with the
same name that is not a port.
easier to scan through a cell's ports. Used that capability in the
"readspice" script to handle case sensitivity problems, and to find
labels that are not ports and force them to be ports to match the
reference netlist.
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).
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.
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.
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.
as long as the command is not attempting to modify the port.
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.
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.
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.
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.
