function that was available in versions 7.1 and earlier that
allows the use of the command "erase errors" to remove DRC error
paint (only when the DRC checker is off, of course).
an error message when reading uses from a .mag file. Also modified
the GDS write routine to provide an error message when an abstract
view points to a GDS file but the GDS file cannot be found.
less confusing. Removed leading spaces in instance path which
could cause a failure to recognize that a path was not specified
for a use in an input file.
from the rigorous method of versioning in case files are relocated
and the use paths are no longer valid. Cells are then searched
for in the search paths in the traditional manner, albeit with a
stern warning. This should avoid most backwards-compatbility
issues.
written interprets the path of every use as either a full
absolute path or a path relative to the parent cell, given the
different ways that a parent cell's path could be specified
(absolute or relative).
the path component of the use def was interpreted as being relative
to the parent when reading the cell def but not when writing,
resulting in paths being interpreted incorrectly.
However, various updates are needed to match changes in magic
over the years, including handling of non-manhattan geometry,
and handling of added DRC rules such as surround and extend.
enabling the "plow" command. At this time, however, not all
rules are being implemented correctly given the numerous changes
to the DRC handling since the last time "plow" was working. Fixes
are ongoing.
file writes by adding the path for each cell use, but being ignored
for file reads. The cell path saved in the .mag file is now honored
on read-back. If the cell needs updating, then the cell version
can be manipulated using "cellname filepath". No UI methods are
currently implemented for managing cell versions.
that are longer than the formerly-fixed array size 256. This
conflicted with the recent addition of holding path data in
properties, where the path coordinates can be significantly
longer than the fixed array size. Same change as made to magic
version 8.1.
rescaling the internal units. The former in particular can
cause problems when moving the root box and importing cells from
a script (same change as made to magic-8.1).
and incorrect call to cairo_set_source_rgba which is in an unused
function and has no effect except with versions of Tcl less than 8.6
where "load -lazy" is not available and unknown functions cause
immediate exit. Cleaned up remaining references to OpenGL in the
Cairo code, and updated the copyright and acknowledged Chuan Chen, who
coded the Cairo interface. No attempt yet to deal with memory leaks
caused by calling Cairo "create" functions without the accompanying
"destroy" functions.
the python preprocessor version, the techfiles and .magicrc file
will get the correct arguments, without affecting the use of CPP
in the configure script.
development had been halted since it was first created back in April.
Version 8.2 is now the official development version, with the first
development push to create a Cairo graphics interface.
