significant amounts of time even though there is no display to
receive the result. However, the "suspendall" command only works
if a window exists. The obvious solution is to set GrDisplayStatus
to DISPLAY_SUSPEND whenever magic is run with the "-dnull" option.
This should help speed up a lot of scripts, in particular where
designs are large.
restricted to its original intent, which is to replace the long name
formed from the plane short name and the "minfinity" coordinate.
This avoids issues with conflicting substrate names derived from a
real layer such as pwell. Also, the global substrate node name now
returns the variable name without the "$" in front if the variable
has not been set to anything. This avoids potential syntax errors
in the netlist.
values in a mask hints property, and added back the handling of
mask hints in the top level cell, since the hierarchical function
on cells does not apply the function to the top level.
earlier today) to "readlink -f", because "realpath" does not exist
on some systems (e.g., CentOS). "readlink" seems to be more
universally available. Noticed that the ext2spice and ext2sim
scripts use /bin/sh instead of /bin/bash, which would cause problems
with some systems where sh != bash.
At the moment the build system hardcodes the path
to the wish binary as it was found at compile time.
For relocatability add a configure flag that allows
the build driver to specify how to invoke the wish
binary at runtime.
By having the build system put in a relative path rather
than an absolute path. Unfortunately, make does not support
computing relative paths manually, so a small bash script is
needed that will do this for us.
- this fixes issue where some of the binary objects would contain an
outdated MAGIC_VERSION if "make clean" was not done after the VERSION
file changes. (e.g., the "Magic VERSION revision REVISION" message in
the wish console and the version requirement checks from a tech file)
"gds write" command, since "Writing cell" is easily confused with
writing a .mag database file. "Generating output" seems clearer
to me. Maybe it's just me.
that have been removed by flattening into the parent cell due to lack
of devices. Previously the checks on writing the subcircuit and writing
the call were slightly different, leading to instances in which the
subcircuit call would be written to the netlist output without the
subcircuit being defined. (2) Corrected an error in the "bridge" CIF/GDS
output operator. In certain (somewhat rare) geometries, the tile behind
(instead of in front of) the corner being checked may be incorrectly
flagged as a DRC spacing error. The fix is to ignore tiles that are
behind the corner being checked.

of input cells on a per-cellname basis, using glob-style pattern
matching. This is probably the best way to deal with 3rd-party vendor
GDS with unfortunate practices like dividing devices up among cells in
a hierarchy, even though it comes across as a bit of a hack solution.
extflat code; failure to provide a forward external reference
to EFHNBest() resulted in a failure to correctly evaluate a
boolean expression. That resulted in a failure to merge
hierarchical nodes during ext2spice, resulting in an incorrect
netlist with single nodes broken up into pieces.
one terminal of a device as the substrate, but also specifies
shielding types for the substrate, then the extraction cannot just
assume that a missing terminal is connected to the substrate without
first checking that there are no substrate shielding types under the
device.
Corrected the "lef write -hide" command option so that obstructions
outside of the boundary are included in the obstruction list, in
addition to the block inside. This had previously been done
correctly for use with the "setback" option but would fail only
for setback = 0.
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.
true, this will force the "gds write" command to write out creation
date stamps as zero. This is very useful for avoiding changing the
contents of an otherwise-unchanged layout, especially if it is in
a git repository where it will force the entire file to be replaced.
and made the default behavior equivalent to "see-vendor". While it is
true that running "cif see" on a readonly cell shows layers that are
not necessarily representative of what is in the file, the opposite
behavior manifests itself in ways that are confusing.
layers that are normally automatically generated to be supplemented
with additional geometry in the form of properties. The first
commit implements a CIF operator "mask-hints" that tells CIFGenLayer
that additional geometry may be specified with a property named
"MASKHINTS_" plus the name passed to the operator as its only
argument. A more extensive commit to be done will allow this
operator to be used on cifinput to use mask hints to retain the
exact geometry of mask layers used in the input file.
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).
routine attempts to rescale the contents of the top-level cell after
moving forward in the GDS to find a cell that was used before it was
defined, if reading that cell caused the scale to change. However,
the numerator and denominator were reversed, causing the scaling to
be the inverse of what it should have been.
Ghazy) to read pin uses from a DEF file, including the three types
that are not defined by the LEF format (go figure). Expanded the
bitmask of label flags to include the additional use types. Also
shifted the label flag bitmask up to make additional room for more
port number, as there is no point in having unused bits in the
bitmask.
to allow a "gds read" command to ignore cells in the GDS which already
exist in memory. This allows magic to be "pre-seeded" with specific
views of cells in the GDS. Default is false, which is backwards-
compatble behavior. (2) Changed the behavior of the the way the use
path is written to and read from a .mag file, checking the path prefix
against Tcl variables PDK_PATH, PDKPATH, PDK_ROOT, and PDKROOT, and
replacing any such leading path component with the variable name.
On reading a .mag file, any variable name at the start of the path
that matches a Tcl variable will be substituted.
