CHANGELOG

TODO

  • extract netlist from layout using PINS and check if connectivity matches intent
  • create a Klayout library so we can also place components from the klayout menu GUI (available for UBC sample pdk)
  • bundle routing for component_from_yaml

master branch (latest changes not released yet)

1.4.2 2020-10-07

  • renamed add_io_optical to add_fiber_array
  • added taper factory and length to add_fiber_single
  • fixed JSON metadata for Components with function kwargs
  • fixed reference positions in component_from_yaml
  • added bundle_routes option in component_from_yaml

1.4.0 2020-10-04

  • Works now for python>=3.6, before only worked for python3.7 due to type annotations
  • nicer netlist representations (adding location to each node in the graph)
  • YAML loader accepts strings (no more io.StringIO)
  • better docs
  • add_tapers only tapers optical ports in the new containered component
  • add_ports from polygon markers
  • add_io_optical maintains other ports
  • added single fiber routing capabilities (pp.routing.add_fiber_single)
  • added Component.copy()
  • added basic electrical routing capabilities
    • pp.routing.add_electrical_pads
    • pp.routing.add_electrical_pads_top
    • pp.routing.add_electrical_pads_shortest

1.3.2 2020-08-15

  • improve sparameters tutorial
  • fixed some issues when using x = x or x_default not valid for x=0
  • added tests for splitter_tree and splitter_chain

1.3.1 2020-07-27

  • get_netlist by default return a simpler netlist that captures only settings different from default. Full netlist component properties available with full_settings=True.
  • limited pytest scope to netlist build tests to avoid weird side effects that move ports locations from test_component_ports
  • sphinx==1.3.2 in requirements.txt

1.3.0 2020-07-26

  • Component.get_netlist() returns its netlist
  • Component.plot_netlist() renders netlist graph
  • component_from_yaml accepts netlist
  • routing jupyter notebooks
  • manhattan text can have cladding

1.2.1 2020-07-05

  • replaced hiyapyco with omegaconf (better YAML parser that can handle number with exponents 1e9)
  • separated conf (important to be saved) from CONFIG that contains useful paths

1.2.0 2020-07-04

  • added link for ubc PDK to README
  • added a jupyter notebook tutorial for references and array of references
  • added dbr and cavity components
  • rotate is now a container
  • addapted pp.pack from phidl as an easier way to pack masks
  • Autoname also has now a build in cache to avoid having two different cells with the same name
  • added type annotations

1.1.9 2020-05-13

  • write and read Sparameters
  • pp.extend_ports is now a container
  • any component decorated with @pp.autoname can accept pins=True flag, and a function pins_function.
  • Pins arguments will be ignored from the Component name and settings
  • better json serializer for settings
  • added units to names (m,K,G ...)

1.1.8 2020-05-11

  • leaf components (waveguide, bend, mmi ...) have now pins, for circuit simulation

1.1.7 2020-05-07

  • flake8 is passing now
  • added flake8 to pre-commit hook
  • simpler JSON file for mask metadata mask.tp.json
  • added container decorator, can inherit ports, settings, test and data analysis protocols and still have a different name to avoid name collisions
  • samples run as part of the test suite, moved samples into pp
  • autoname sorts kwarg keys by alphabetical order
  • added autoname tests
  • autoname accepts max_name_length and ignore_from_name kwargs
  • pp.generate_does raises error if component does not exist in factory
  • replaces name_W20_L30 by name_hash for cell names > 32
  • zz_conn cleaner name using from pp.name import clean_name no slashes in the name
  • add_io is a container
  • write labels settings in the middle of the component by default, you can always turn it off by adding config.yml in your project
  • added pytest-regression for component setting and ports
with_settings_label: False

1.1.6 2020-04-11

  • mask JSON works with cached GDS files for the klayout placer
  • added layers to CONFIG['layers']
  • write_labels gets layer from CONFIG['layers']['LABEL']
  • add_padding works over the same component --> this was not a good idea, reverted in 1.1.7 to avoid name collisions
  • import_gds can snap points to a design grid

1.1.5 2020-03-17

  • added pre-commit hook for code consistency
  • waveguide and bend allow a list of cladding layers
  • all layers are defined as tuples using pp.LAYER.WG, pp.LAYER.WGCLAD
