Matthias Koefferlein 0f1dc1d191 Refine pin mismatch handling so that only 'not used' nets will make a pin match against null. 2019-11-24 16:40:45 +01:00
Matthias Koefferlein afacf7c0b5 WIP: fixed a segfault in the netlist browser. 2019-11-24 01:28:07 +01:00
Matthias Koefferlein 64bb01d80d Dropped attempt to remove dummy nodes from spice reader netlist as this wasn't effective anyway. 2019-11-24 00:23:19 +01:00
Matthias Koefferlein ed00503d41 Fixed Spice reader: must not use Netlist::purge_nets to remove dummy nets. Updated golden test data. 2019-11-23 23:36:52 +01:00
Matthias Koefferlein aa28aa807a Unit tests fixed and a bugfix in the netlist compare 
One unit test was failing because the netlist compare did not
properly consider dropped pins:
* A severe bug ("g1" should be "g2")
* Incomplete detection of dropped pins upwards in the hierarchy

The general pin and net mapping scheme has been enhanced so that
net mapping to "0" is valid (this will happen in case of dropped
pins) and this condition is used to detect pins without match
requirement.

Matthias Koefferlein 4fe5a96596 Implemented #426 (feature request: group techs) 
The tech group is a new XML tag "<group>...</group>".
This tag is editable in the tech "general" page as "Group".
If non-empty, a submenu will be created in the tech selector
menu for all techs with the same group.

Matthias Koefferlein 247bfa9ac5 Implemented #407 (variables in technology base path) 
The implementation uses extrapolation of strings in the
"Expressions" framework.

There is how:
* $(tech_name) -> substituted by the technology name
* $(tech_dir) -> substituted by the directory the technology file is stored in
* $(tech_file) -> substituted by the absolute path to the tech file
* $(appdata_path) -> substituted by KLayout's home directory (e.g. ~/.klayout)
* $(env('X')) -> substituted by the environment variable $X

Matthias Koefferlein 6648b53822 Fixed issue #419 (multiple top circuits after flatten of netlist) 
The problem is solved by always producing subcircuits for cell
instances, even if there are no connections.

The netlist comparer had to be adjusted too because subcircuits
without pins were used for representing "unknown" subcircuit pairing.

In addition, this patch should lead to a better matching of
parallel subcircuit configurations where two different subcircuits
are entirely parallel.

Matthias Koefferlein bdf5e3c124 WIP: fake pin debug issue with LVS 
Fake pins: pins that happen because something connects to a cell at an
unexpected position. Such a pin is difficult to find. The solution is
to keep those nets and nur purge them so these nets can be identified
in the layout.

Here: is_floating? will be true only if there are no pins. Hence
nets with pins are not removed. is_passive is introduced for nets -
passive nets are such that don't have elements, but a pin.
Circuits are purged if they only have passive nets.

Matthias Koefferlein 506cfc1c6f WIP: attempt to retain nets which don't have active elements but pins. This is supposed to simplify debugging in case of fake pins. When removing those nets, the pin is very difficult to find. 2019-09-30 20:58:55 +02:00

Matthias Koefferlein 550e2622bf Put more amphasis on net names to resolve ambiguities 
The problem was that with the floating test case, the
ambiguity resolution sometimes assigned the wrong pins
and floating pins/connected pins were swapped.

One option is to make the ambiguity resolver consider
the pin connection state when tenatively evaluating
nodes.

Another option is to put more emphasis on net names
and use them for ambiguity resolution. This has helped
here.

Matthias Koefferlein 60ed0cdc89 Updated test golden data (mainly: nets are not purged when there is a subcircuit pin on it) 2019-08-29 23:26:03 +02:00
Matthias Koefferlein b1acfe9587 Tried a better deal with floating pins 
1.) is_floating is now only true if there is no device
    and no subcircuit on a net. This means we only purge
    nets if they are really floating. So far we purged
    nets without pins which lead to the mismatch:

    Before purge:
      Layout:            (net) <--> DEVICE.TERMINAL
      Schematic:           PIN <--> DEVICE.TERMINAL

    After purge:
      Layout:           (null) <--> DEVICE.TERMINAL
      Schematic:           PIN <--> DEVICE.TERMINAL

    (null does not match any net)

2.) circuit pin matching was a bit picky. Only when
    one circuit did not have pins, matching was sloppy.

    In real cases however, circuits may have unconnected
    pins:
    - top level pins without a counterpart (no label)
    - subcircuits pins which are not used

    We catch both cases by refining the match: if a pin
    is not used, it does not need to match against
    any other pin. It's reported as "matching against null"
    though.

Matthias Koefferlein 444e10d32f WIP: rerun LVS, partial LVS 
Rerun LVS: a button is provided which allows re-running
the LVS or netlist extraction from the netlist browser.
TODO: a generic concept for triggering the generators

"Partial LVS" is a feature where it's possible to
select a layout subcell - running LVS then will only
compare against the corresponding schematic subcell, not
the whole tree. The magic is done by "align" which will
remove the upper hierarchy part.

Matthias Koefferlein 1bc03c3b79 Implement "M" parameter for Spice 
This implementation is pretty simplistic and

* C: C(final) = C*M
* M: W(final) = W*M
* D: A(final) = A*M
* Q: AE(final) = AE*M

The other parameters (specifically the other
geometry parameters) are not scaled yet.

Matthias Koefferlein 49c1bacb98 Introducing variables for layout queries: 
1.) The ExpressionContext class is a mapping of tl::Eval
    and allows providing a variable context for the LQ.
    Expression class is derived from ExpressionContext now.
2.) The variable lookup has been changed so that variables
    can be modified even if they come from a parent context.
3.) LayoutQuery and iterator has been given an argument to
    supply the context

Matthias Koefferlein b4fa4b1bae Flattening of layout with circuit flattening. 
Technically, the layout isn't flattened, but connections are made
which allow regenerating the layout even after the circuit
has been flattened.

Matthias Koefferlein 9cad9ca024 Fixed missing initialization of device_scaling in LayoutToNetlist. 2019-07-24 20:49:56 +02:00
Matthias Koefferlein afb5cea576 Added "device_scaling" to LVS 
Plus: added some missing files

Implementation details:
* scaling factor was introduced in DeviceExtractor::extract
* for easy implementation this is available in "sdbu"
* "sdbu" is made available in GSI
* to test this, the db::compare_netlist had to be enhanced to
  exactly check device parameters
* enhancement of LVS script framework and doc updates

Matthias Koefferlein cef96902ad Boundary for circuits, reverted automatic generation of global pins 
- global pins have been generated for device cells too and lead
  to implicit pins which may not be desired. The original problem
  was how to make abstract circuits comparable. This has to be
  solved differently.

  abstract circuits

Matthias Koefferlein 993ef78575 WIP: some cleanup/enhancement 
General topic: abstracts and swappable pins.
Issue: we work bottom up and assign pins. This is the
basis for net graph building. But swappable means those
pins can change. The compare works fine, but debugging
output is strange: as the pin assigned is fixed, the nets
found to be attached to a circuit might not fit any
proposed pin pair (which does not contain swapping).

The problem gets worse with abstracts.

The enhancements are
- Such cases generate only warnings in the browser
  and the message says swapping might be the case
- Floating nets are treated differently. This should
  lead to a better performance for abstracts/black boxes,
  but in case of disconnected pins (due to wire errors),
  floating nets happen to create mismatches in the nets above.
- Net graph building does not consider swappable nets. In
  case of two swappable pins this wouldn't be an issue, but
  for more than two this would create ambiguities and
  prevent topological matching.

Plus: Debug output option for net graph
