Matthias Koefferlein 0d623bc57a Avoid netlist extraction issues with duplicate instances 
So far, duplicate instances have lead to net propagation
into parent cells and floating nets. This is fixed by ignoring
duplicate instances where possible.

Matthias Koefferlein ebd00c186b Enhancements for net export feature 
- some refactoring
- better performance (was slow because layer iteration
  was done outside of loop and recursive cluster iterator)
- with selected nets, only the required hierarchy is
  produced. For this a new argument is added to
  LayoutToNetlist::create_cell_mapping (nets) which
  allows selecting the nets for which a cell mapping
  is requested

  comments
* < and > are allowed chars in spice names now
* global net names have second prio over labels now

Matthias Koefferlein 548f16f1df WIP: tried to provide a more consistent net building feature (here: building hierarchical nets with properties as net annotation - needs cell variants if properties are assigned to subcells too) 2019-05-04 00:37:38 +02:00

Matthias Koefferlein 7f9da5e8de Introduced concept of device class templates 
This concept allows to persist at least the standard
(built-in) device classes into L2N DB files. This way
device classes are persisted.

Matthias Koefferlein eabf558186 netlist exaction: selective net joining with labels 
Now, a glob pattern can be used to identify the labels
which implicitly join nets. Also, net joining now
only happens on top level.

Matthias Koefferlein 9613ad72c8 WIP: netlist compare - using it for more tests 
Issue solved: some circuit pins may not have a net - these
need to be ignored.

Requirement: all pins with a net must be mapped.

Detached pins are not present in the mapping table.
A dummy mapping table was introduced to allow dropping
of pins in the second circuit too.

Output of compare should not depend on memory location
anymore and pin mismatch reporting should include all
pins.
