Removes the shell serialisation `for .. in ..` expression
This provides another significant speed up, after */Depend was made
parallel. x3+ speedup over -j1.
Previously it would only build the 'scmos' subdir when the
'make install' target is running, which is done sudo. This
would result in a number of files in scmos/cif_template/objs
to be owned by 'root'.
Renamed TECH to TECHS which is inline with the other caregories
MODULES and LIBS.
This was more a clarity matter as relocatable autoconf makes all
references to the path look longer and more unweildly making it
a variable makes shorter and easier to read work through.
Especially when related to risks with RM arguments using the output
of a shell call in the argument list. What could go wrong ?
This target consumes ~50% of the total build time due to the
serialization of the shell for loop method.
Also the removal of the */Depend is deferred to the subdir
Makefile's responsibility.
This is a series of updates to make building magic far less of a headache:
* Drop `csh`/`tcsh` dependency and detection from `./configure`.
* Rewrite makedbh in Python.
* Rewrite printmans in POSIX sh.
* Stop deleting Depend before every compile (which causes some files to recompile and thus increases recompile times significantly)
* Add Depend to CLEANS in scripts/defs.mak.in
* Turn POSIX suffix rule in magic/rules.mak to a pattern rule with proper prerequisites
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.
processes "interaction areas". This should eliminate weirdnesses
where errors will fail to show up in a subcell that does not
interact with paint or other subcells in the top level edit cell.
These errors cannot be reported directly in the top level cell,
but a new error message has been created to direct the user to
check the subcell for errors. Also: Modified the toolkit procedures
to force DRC to be run on newly created or modified parameterized
cell layouts. There is some oddity about the process that causes
DRC errors to be delayed unless a print statement is put before the
DRC check; I would like to investigate this further.
