Matthias Koefferlein 4acc4b96e2 First attempt to fix the issue
Problem was caching which did not take into account the array nature
of instances.

This fix also moves the cache one level below so it is effective also
when instance tree traversal happens. This might speed up things too.

Needs testing.

Matthias Koefferlein baffb940d1 Implemented #429: final touches to doc and tests for RBA/pya API. 2019-12-01 16:41:27 +01:00
Matthias Koefferlein 9eb09c3a5d Enhancements to implementation
- OASIS layers are turned into pure layer name (not lxdy_name) for
  MAG output
- Boxes of instances had been incorrect
- consistent naming of cell files in presence of special chars
2019-11-30 22:30:28 +01:00
Matthias Koefferlein c6ede46fd0 WIP: substantial changes
- force lower-case layer names to allow CIF/MAG loop (CIF needs
  upper-case layer names, MAG doesn't)
- reverted CIF reader to standard
- new options for writer: tech, "zero timestamp".
- file name MUST be consistent with one cell name.
  Reason: it's not possible to derive the initial
  cell from the given options, so without the file name
  being consistent, we can't know what to write there.
  Basically the file name rather supplies the path.

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.

2019-11-22 23:11:05 +01:00
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 991778f718 "breakout cells": attempt to provide a solution for SRAM

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.
