Matthias Koefferlein 25e2151e28 Tiny enhancement of measurement algorithm gives more reliable results on auto-measure for 'any direction'. The solution is taking vertexes into account and accepts them as counterpart for the seed. 2019-09-02 22:58:42 +02:00
Matthias Koefferlein 2e695bd048 Leaner solution: provide snap and swap 
"Swap points": will swap P1 and P2
"Snap both": will take P2 into account (before it was only P1)
 2019-09-01 23:14:21 +02:00
Matthias Koefferlein 9fa5277e41 Implementation proposal 
The solution tries to be a bit more generic:

- four buttons are there to synchronize coordinates
- three buttons to snap p1, p2 and auto-measure from p1.

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 f6492c80c5 Stream import: support multiple files 
Multiple files can now be selected for "File/Import/Other Files into current".

NOTE: performance for many files may not be excellent
due to re-sorting of hierarchy and bounding box re-computation.

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
applies "M" the following way:
* R: R(final) = R/M
* L: L(final) = L/M
* 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 e148898d4c Fixed an issue with drawing canvas and undo 
When a "create instance" operation with a library cell
was undone the following issue could be seen: as the library
cell might create new layers in the target layout, these
needed to be undone when the operation was reverted.

But then the canvas bit planes got messed up because the
"LayoutView::set_view_ops" call was missing. Now this
happens inside the manipulation functions for deleting
and inserting layers. This should also reduce the
necessity to call LayoutView::update_content explicitly.
