generation in the "cifoutput" section of the techfile. This operator
solves the problems with the catecorner position of geometry when
attempting to automatically close up gaps between islands of a layer.
works for the first pair of types/plane being below the second pair of
types/plane (upward fringing from the top of a wire to an overlapping
wire above it), which was not being handled due to an implicit assumption
that plane1 < plane2, which does not have to be the case.
Before this modification "directed" surround rule only worked for layers1 and layers2 belonging to the same plane.
After this modification the "directed" rule works also for different planes, even if layer1 is a contact type.
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.
memory for the input line instead of using a fixed 1024-character
buffer. That avoids the issue of rare but possible overflow when
reading a .ext file with unknown line lengths.
a truncated line. There is still a question as to why an example
occurred that caused a line to be truncated, and whether a buffer
size needs to be made larger or made dynamically allocated.
change from passing the HierName to passing the HierContext (of which
HierName is a part) so that more information from HierContext (such
as the cell use being visited) can be passed to the callback
procedure (largely for diagnostic purposes).
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.
probably needs revisiting, because "lef write" and "lef writeall"
need handling to generate the PROPERTYDEFINITIONS block for the
PROPERTY entries to be correct.
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.
templayers. This permits some useful interactions like growing to
the size of a bounding box, or abutment box, as well as many other
possibilities. Also: Corrected the use of "cif see" for the boundary
(abutment box) layer, which was not working because the "cif see"
command uses a flattened CellDef that does not have the boundary
property of the cell it was flattened from.
layers (apart from the fact that contacts are output as magic's
contact layer representation, and not as cuts; this still needs to
be handled properly).
or more repeated "equiv" lines in a .ext file. This implies two
ports with different names are connected, indicating probably a bad
layout, but that's not a reason to have magic crash.
I missed the LAYER value and the geometry was one level to high.
