extraction: Fixed a problem causing long extraction times, at
least some of which had to do with a poor string hash function
implementation. Fixed a huge problem in ext2spice, where the
node merge function was particularly poorly implemented, causing
exponentially increasing processing times with layout size.
Corrected a minor issue with ext2spice where arguments were
improperly specified, causing unnecessary error messages to be
issued. Fixed an error in the "load -dereference" command option,
which again caused unnecessary error messages to be issued.
Changed .gitignore to ignore Depend files, which are now regenerated
on every build.
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
name prepended. For example, when selecting a net in a standard
cell design, a terminal would highlight the name "OR2X1_1/B"
instead of just "B".
distributed installations, where the immediate installation location
is different from the final installation location, but in the case
where it is not desirable to put the entire install hierarchy as a
subdirectory of DESTDIR.
only at the time of running the command "load". But cells are generally
loaded only on an as-needed basis, so the dereferencing option must be
saved as a flag in the cell and honored whenever its subcells are expanded
or otherwise read at a later time.
