Tim Edwards 02bbb1064e Corrected an error in "extresist" that can output an incorrect
number of terminals for devices that don't have the usual gate/
source/drain terminals (e.g., diodes, resistors, capacitors) when
writing the devices with re-mapped terminals into the .res.ext
file.  Also:  Changed the size of the word containing the name
refcount for "equiv" statements, since an accidental shorting
of pins can cause a large number of "equiv" statements in a .ext
file, causing an overrun of the previously 1-byte refcount (this
probably does not make the structure any longer, since it likely
has to fit to a word boundary).

Tim Edwards 65ef9a1ad3 Final (I hope!) corrections to the "def write" command. 2022-11-19 22:02:44 -05:00
Tim Edwards 0dac37cb46 Changed the behavior of GDS writing to halt with an error if an
attempt is made to write an abstract view to GDS.  This behavior can
be overridded with the new command option "gds abstract [enable|disable]".
Also:  Corrected extraction to allow split tiles to be set as the
reference tile for a node.  Previously this was allowed only if the
tile was the first to be searched, but that can cause different tiles to
be marked as the reference depending on where the search starts,
resulting in different names for the same node in .ext files, which is
bad.  Also:  Modified the LEF annotation to avoid bad entries in the LEF
that would create layers in the layout where none exist.

Alessandro De Laurenzis b306a39560 Compatibility with C99 standard
This commit makes the code (mostly) C99-compatible, enabling to compile
it without the -Wno-error=implicit-function-declaration flag. This
way, Magic becomes usable on arm64 architectures, specifically on Apple
computers with M1/M2 SoC.

Tim Edwards 43d5cc2804 Added a quick check on cell defs when running "antennacheck" to
make sure that the cell def's .ext is not marked "abstract".
Otherwise, "antennacheck" appears to run, but no output is
produced, and no reason is given.
2022-06-20 12:26:23 -04:00
Tim Edwards 468a8ae0be Added a 2nd use of the "device" property, which has long been needed,
which instead of defining a device or subcircuit that exists inside
the cell, instead redefines the cell itself as a device or subcircuit
model that exists in the PDK.  This is used where a specific layout
subcell has its own associated device definition in the PDK.  Instead
of the "device" property value being the line that gets generated for
a device in the subcells .ext file, the property value should be the
word "primitive" optionally followed by any parameters that need to
be passed to the subcircuit call.

Tim Edwards 9a17539ca7 Corrected the use of EF_SUBS_NODE to distinguish between device
substrate (bulk terminal) and global substrate.  Otherwise, the
routine in ext2hier.c that finds the substrate node will find the
first device bulk connection, not the default substrate.

Tim Edwards 5e3c26c95a Tracked down two more memory leaks coming from ext2spice, due to
client data generated by ext2spice and attached to a node's
nodeClient record;  there is an initNodeClient() routine but no
corresponding freeNodeClient() routine.  Eventually had to add a
callback function passed to EFDone() and EFFlatDone() to clean up
these entries.  After doing that, valgrind reports clean for all
memory allocated within ext2spice (there are other things that are
not freed but not related to a specific command, so do not need to
be treated as leaks).
2021-12-13 18:05:53 -05:00
Tim Edwards 7297ca079f Found another long-time error in which a hash table created during
ext2spice is not freed.  This may account for the rest of the memory
leak that was partially fixed in the previous commit.
2021-12-13 16:55:02 -05:00
Tim Edwards 9f7011333a Fixed the behavior of the "def write" command, which was not
clearing the "subcircuit" flag from the top level cell, causing
only nets connected to ports to be output.
2021-12-06 10:56:59 -05:00
Tim Edwards 5913643ad0 Reverted most of yesterday's modifications. Instead located the
issue at the change made in revision 214.  This was done incorrectly
in two ways, one being a set of statements inside an if() block that
should have been executed always, and the other an incorrect use of
the EF_DEVTERM flag, setting it when it should not have been set.

Tim Edwards 6a8f1226d1 Corrected a problem with implicit substrate ports and connections;
implicit substrate connections under some conditions were not added
to the subcircuit pin list.  When this was corrected, the call to
the subcircuit was missing the implicit substrate port.  When that
was corrected, the implicit substrate port printed was the subcircuit's
local node name, not the connection from above in the hierarchy.  The
underlying problem was that the substrate was marked as a port in a
node record that was in another (flattened and unused) def and so not
seen when enumerating the def's node list.  It's possible that the
better solution is that the efNodeHashTable() should be enumerated to
write subcircuit ports, not def->def_nodes.  However, now, by using
EFHNLook(), the corresponding entry in efNodeHashTable() is found and
used.
2021-12-02 11:38:46 -05:00
Tim Edwards c0ea133e98 A recent commit caused connections to implicit (unlabeled) substrate
to not get into the subcircuit port list during ext2spice.  The new
fix brings back (unfortunately) the behavior of creating a substrate
node for cells that have no substrate connection to any device;
this will have to be handled separately.
2021-11-03 17:34:38 -04:00
Tim Edwards 59fc24729c Corrected issues in the extresist function found after the previous
commit, mostly relating to the scale of values in the ".nodes" file
produced by ext2sim.  Making this file CIF syntax seemed unnecessary,
so I removed the CIF syntax and scaling.  "extresist" can now produce
an apparently valid output on a standard cell layout.  Even with the
change, the extresist output is still only pseudo-hierarchical, so
this does not preclude the need for eliminating the .sim format file
in favor of the .ext file, but it provides a working intermediate
form.
2021-04-21 13:03:26 -04:00
Tim Edwards fd4569081e Added a reference count to the node structure in extflat to account
for the "equiv" statement---equivalent nodes names have to be
registered in the def->def_nodes hash table, and if they point to
the same node, then that node can't be free'd until the last
referenced node is seen when iterating through the hash table to
free the node records during EFDone().  This is handled by the
reference count.
2021-03-17 14:54:36 -04:00
Tim Edwards 83808dcf79 Corrected an error that was causing disconnects in the hierarchical
SPICE netlist output that appears to have come from flags created
for writing DEF that inappropriately got set during ext2spice.
A redundant call to efAddNodes() was adding confusion by appearing
to handle most cases but actually missing some.  With the corrected
flag, the redundant call is really redundant and can be removed.
It has not been tested whether DEF output is affected by the change
(DEF output from magic is rarely used, anyway).

Tim Edwards 2af38a4191 Updates from running the fix-ending-whitespace script. 2020-05-23 17:13:14 -04:00
Tim Edwards 2569a06c1f Substantial improvements on several fronts, mostly to do with
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.
2020-03-13 10:33:44 -04:00
Tim Edwards d3eb03d19a Additional correction to extraction, still part of the effort to
remove redundant ports.  A comment that I left in the code at the
last commit asked if it was necessary to call efAddNodes and
efAddConns recursively.  An example came up in which the answer
is apparently "yes".  These routines have been replaced by
efFlatNodes(), which appears to solve the problem.  There is now
a question of whether efFlatNodesDeviceless() does anything, and
should its main behavior (to flag deviceless subcircuits) be
folded into efFlatNodes.
2019-11-17 19:08:47 -05:00
Tim Edwards 0eb3b1fe1c Corrected an error in ext2spice related to the recent modification to get
rid of redundant port entries in subcircuits.  There is still an outstanding
issue as to whether nodes and connections need to be recursively iterated
to the hierarchy bottom.  The current fix corrected the test case.  Also,
added a "-dereference" option to the "load" command to revert to the
original behavior of using only search paths from "addpath" when searching
for files to load.
2019-11-14 15:18:26 -05:00
Tim Edwards c342178458 Made some changes to the way that ext2spice generates subcircuit
ports, to avoid creating ports for node names that are redundant.
It would probably be better to avoid creating the redundant node
names in the first place;  however, I am less certain why these
are generated.  The incorrect additional ports all have hierarchical
names in the cell, which is a sign that they are incorrect, as the
cell itself should not have any parents.  The level of certainty
about this fix is definitely not 100%, but it was tested on a
hierarchical analog design, and setting levels of parasitic caps
caused new nodes to appear in subcircuits and in no cases did
information appear to be lost.
2019-10-29 09:44:28 -04:00
Tim Edwards a4ea827d1e More corrections to extresist, which now appears to work if used
with ext2spice without the hierarchy option.  More work needed to
produce correct hierarchical output and to support extraction
devices other than the old "fet" record.
2019-10-28 13:10:16 -04:00
Tim Edwards d9ccd711d9 Realizing that the "no such node" messages were directly related to
the below-threshold coupling caps being removed from the hierarchy,
added code to suppress the error message when it is clearly related
to a below-threshold cap that has been removed.
2019-10-23 11:59:59 -04:00
Tim Edwards 39ab59e7ec Corrected error causing a crash when parasitic extraction is
invoked on a layout with an array of instances.  Also, continued
implementation of antenna violation checking (not done yet).
2019-10-18 14:12:52 -04:00
Tim Edwards 9f5936c7cb Found an additional scaling-up problem in ext2spice (previously handled
a scaling issue in extract) which was caused by the addition of
hierarchical netlist generation.  Finding hierarchical connections
requires finding instances by name, so it is vastly better to create a
hash table of instances instead of a linked list.
2019-02-07 10:54:07 -05:00
Tim Edwards 742a1dbac4 Corrected an error in which ext2spice fails on hierarchies of
cells with abstract views on all leaf nodes using the "LEFview"
property to declare the cell view to be abstract.  Such cells
were being misinterpreted as containing no active devices.
2018-03-27 18:18:26 -04:00
Tim Edwards 088fc759c4 Set of changes updating version 8.2 to the level of 8.1, since 8.2
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.
