Previous commits changed the port IDs to an integer rather than a
bitfield. However, the first and next commands were utilizing that
a -1 became a large positive integer when masked. This resulted in
the min port operations failing. Added a default comparison with -1
to fix the problem.
reading GDS files, caused by an unneeded change to pass both
the "original" filename and the actual filename when handling
compressed files---The original filename is unneeded.
(2) Implemented several new methods for parasitic extraction. The
first is an option offset value to apply to sidewall calculations.
This handles issues where actual wire separation is different
from drawn wire separation, which can be significant for the
1/d calculation of sidewall coupling. The second method is to
use the recently-added fringe halo to compute the coupling of the
fringe capacitance to nearby wires. Prior to this change, all
fringe capacitance was applied to surfaces directly under a wire
edge as if the fringe capacitance did not extend outward from the
edge. Now the capacitance is properly pro-rated for the position
of any overlapped shape inside the fringing field. Finally, the
third method added is a new search algorithm for finding the
nearest shapes along the length of a boundary. This is used for
sidewall coupling and fringe shielding, where the nearest shape
dominates the coupling, and any shapes behind are shielded and
may (to first order) be ignored. Previously, the entire halo
was searched without regard to shapes shielding other shapes
behind, and a recent correction added an ad-hoc search for
blocking shapes that was inefficient and not always correct.
The new method is both efficient and accurate.
Compression levels of the output can be controlled with the "gds
compress [<value>]" command, where <value> 0 (default) is uncompressed
output, 6 is "normal" gzip compression, and 9 is maximum compression.

of systems calls to "gzip" and "gunzip". A compressed GDS file can

recognized as a valid command when file locking has been disabled as
a compile-time option. The command then generates an error on
"locking enable" but simply ignores the command "locking disable".
fact that "extract all" does not enumerate cells from bottom up
as I had assumed---The order is roughly bottom-to-top, but cells
re-used in different places in the hierarchy could end up called
before one or more of their own subcells is extracted. Since
this conflicted with the preparation of the substrate in each
extracted subcircuit, I changed the method to enumerate cells so
that it is properly bottom-to-top. Also, methods were added to
"extract" (incremental), "extract cell", and "extract parents"
to ensure that the substrate is prepared on all subcells before
extraction.
to be annotated from a DEF file. This is particularly useful if
"def read" has been used without the "-labels" option, and the
labels are needed at some point.
in github issue #149. This causes magic to no longer write log files
for "make" and "make install" but will properly exit with a non-zero
return code on any error during compile.
Also: Corrected the command "tech drc surround <type1> <type2>" so
that it now returns the correct value when <type1> and <type2> are in
the same plane. Added new command "tech drc directional <type1> <type2>"
which works the same way as "tech drc surround" except for directional
surround rules. Used this to generate vias from "def write" with the
correct metal surround amounts included in the via definiton. The
route analysis then ignores tile slivers that make up the surrounding
material around contacts. Also implemented a method that handles
routes that are made of multiple thin tiles due to the maximum horizontal
stripes rule. Now magic handles "def write" well except for not dealing
with non-minimum-width routes unless they're specifically called out as
"special" nets.
The extSubtree() routine cuts a layout into squares and extracts
each separately, checking for subcell interactions. In each
square it parses all labels looking for unconnected ones. This
section of code not only parses all labels M x N times, but it
then marks interaction areas where there may be none, forcing
additional unnecessary processing. This commit makes the first
quick optimization, which is to change the return value of
DRCFindInteractions() from boolean to integer, allowing it to
return a value indicating that there are no subcells in the
area. This prevents the loop through labels from happening in
cases where there can never be interactions. More to come.
traditionally been kept for backwards compatibility. However, the
operation of "ext2spice" and "ext2sim" as separate programs has
become extremely difficult to maintain, and so it has been dropped
in favor of folding both into the program as commands, as was done
a long time ago in the Tcl/Tk version.
timestamps that are fixed, since the timestamp update routine is
called from too many places, too many times. Instead created a
new cell definition flag indicating a fixed timestamp, which can
be set by "cellname timestamp" for an individual cell, or with
"gds datestamp" for cells read from a GDS file.
the timestamp is updated after reading in CIF or GDS, and managed to
get the timestamp dirty flag to remain clear after reading when
"gds datestamp" is used. This includes a modification of the timestamp
update routine that only updates timestamps on a single file if only a
single file is being written.

yesterday's commit to allow the syntax "gds maskhints <types>", in

The website documentation now points to these contents in a clone
of the repository on opencircuitdesign.com, so all future edits of
the command-line documentation will be made directly to the git

microns from 2 to 3 digits after the decimal place, so that 5 nanometer
grids do not get values clipped in the output.
"gds datestamp <value>" as an option to force a specific datestamp
on the GDS output. This is a third option beyond the previous two
which were either to use the current time or to write zero. The
new option allows an entire library to get a common timestamp, for
example, related to a PDK version number. The "gds nodatestamp"
option has been retained for backwards compatibility.
in a cell to account for the difference between what's in an input
GDS file and what magic would write out itself from the processed

will generate the equivalent mask data as output without resorting
to using GDS file references as properties. The method is activated
with the new command option "gds maskhints on" and the default is
off.
If cells are instanced before being defined, causing the GDS parser
to rewind the cell from the top, then the "already defined" error
messages will be suppressed, since it is to be expected that cells
will be seen twice (and ignored the 2nd time). When rewinding, an
output message is issued so that it is clear that the file contains
instances that are used before they are defined, and recommends the
"gds ordering on" setting. Also: Fixed the "gds ordering" command
code so that the command with no third argument returns the state
of the "gds ordering" setting instead of generating a parser error.
node representing the global substrate on cells that are abstract
views. Corrected a typecasting issue in ext2spice.c that throws
a compiler warning. Added another check for a cell being editable
when painting, which is a case that was not covered by the
previous code change to address the same issue.
there was no distinction between a locked file and a new cell
(initial state) before writing to disk. This prevents any new cell
from being saved! Also: Revised the behavior of the "select short"
search, but this still has issues with long run-times on complex
layouts, so this is an ongoing effort.
whenever a process writes a cell to disk, it immediately releases the
file lock it had on that cell, which is clearly not the intent of file
locking. Fixed this issue. On a related topic, revised the "cellname
writeable" command so that it can make a cell editable even if the cell
has an advisory lock and cannot be made writeable. Perhaps there should
be a clearer distinction here between "writeable" and "editable". Also:
Reconsidered the previous commit, which removed the "--disable-locking"
from the configuration options. Because some operating systems may not
implement fnctl()-based file locking (Cygwin, for one, apparently doesn't),
it is still useful to be able to completely remove the function, in case
the operating system will fail to recognize the fnctl() values in the
code. Now, file locking behavior can be permanently removed through the
configuration option, or temporarily disabled from the command line.

this limited ports to 16384, which seemed reasonable at the time.
However, the sky130_sram_macro layouts connect power and ground in a
way that when coupled with "extract unique" can generate tens of
thousands of ports and overrun the bit field, showing that automation
can do the unexpected. The solution was to split out the port number
from the label record as its own 32-bit value.
connections through the substrate as the same node, and so will
not force different nodes names on the soft connection to be
unique. This should probably be selectable behavior. However, as
written, the "extract" command will always merge soft connections,
so giving them unique names just causes problems with "extract".

of the currently edited cell if nothing is selected; "cellname
rename <name>" renames the currently edited cell to <name>.
Modified the "extract" command so that it will not extract a cell
named "(UNNAMED)" but will insist that the cell must be given a
proper name, much like the "writeall" command does.

doing "spliterase" on a zero-area rectangle (which does not cause
a segfault, but is not what one would want magic to do).
an optional extra argument to the "select" command that can be used
to select labels by glob-style matching; e.g., "select area labels
VSS*" or "select less area labels *_1". This will help in managing
labels after flattening a standard cell design; e.g., by using
"select less area labels */VDD".
to eliminate all redundant names resulting from redundant labels.
Changed the behavior of "goto" so that it will find local names with

equivalent to the node name used elsewhere in the file. This
limits unnecessary output of "equiv" statements that can bog down
ext2spice and other commands that use the .ext file contents.
require that an edit cell be defined. This stops a lot of commands
from failing on non-writeable cells. There really should not be a
concept of "non-editable" cells at all, just non-writeable ones.
that can be used to force renaming of a read-only cell. The
action revokes the read-only status of the cell and removes any
GDS filename and pointers from the cell's properties. This can be
used to swap out a library cell in a layout for a custom version,
by first forcing a rename of the cell, and then resetting the
filepath of the cell and flushing.
is not necessary that the target cell not exist. That allows a
layout to be flattened into a destination in pieces. Also found
that the "flatten" command never frees memory for the CellUse it

that nobody can make temporary edits on the cell in memory, which is

not possible to make the cell show as edited and editable until leaving

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

against one (e.g., all transistors intersecting deep nwell).

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.
The previous behavior was to generate hierarchical names for all
labels when copying contents of subcells. This is "safe" for
copying selections without accidentally shorting things through
labeling, but it can make a mess of the selection. Options are
now "select do labels" for the existing behavior, "select no labels"
to not show any labels, and "select simple labels" to show only the
root name of labels in subcells.
GDS_FILE property in the same way that it handles changes to the

This avoids issues with conflicting substrate names derived from a

This effectively supercedes the technology version number. (2) Changed

could have multiple ports of the same name. This problem had been
worked over before, but there was an indpendent mechanism producing
the same result for a completely different reason, caused by subcells

used both for counting cells during GDS write and for saving
geometry data from the "copyup" operator during GDS read. The write
routine does not clear the client record, and the read routine was
checking if the cd_client value was default. Corrected the resulting
crash condition by resetting cd_client before GDS reads. However, the
underlying problem is that the GDS read is reading data into a cell
that already exists in the database, and is not handling it robustly
by renaming the existing cell. So this should be revisited.

forces all ports in a cell to be reordered in alphabetical order,
which ensures that the output of "extract" is always the same

by iterating through the hash table).
could cause serious errors on systems that do not auto-zero allocated

"extresist on" option.

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

cell design, a terminal would highlight the name "OR2X1_1/B"
instead of just "B".

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

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).

avoids changing the actual bounding box of the cell to match the
