| Version history: | ||
|
|
||
| Lukas Chrostowski 2015/11/11 | ||
| - Optical_net class | ||
| - find all LayerSi paths and waveguides, and save optical net vertices | ||
| - find all PinRec paths | ||
| - find all DevRec polygons and boxes | ||
| - check_waveguides | ||
| - waveguide bend minimum | ||
| - paths with corners (more than 2 points) | ||
| - bend radius less than specified | ||
| - error marker layer and class; clear errors | ||
|
|
||
| Lukas Chrostowski 2015/11/12 | ||
| - determining where pins/waveguides overlap to generate a netlist | ||
| - initial Spice output for components including waveguides and nets. | ||
| - check nets & components | ||
| - incorrect number of nets connected to a component (disconnected, or too many) | ||
|
|
||
| Lukas Chrostowski 2015/11/15 | ||
| - fix for Python 3.4: print("xxx") | ||
| - moved some functions from here, to the common "SiEPIC_EBeam_functions file, so they are accessible elsewhere. | ||
| - added pin# text label on PinRec layer; sort pins in Spice output using these names. | ||
|
|
||
| Lukas Chrostowski 2015/11/16 | ||
| - fixes for component pin_type = Optical IO / FbrTgt being incorrectly handled; added Optical_pin.pin_type | ||
|
|
||
| Lukas Chrostowski 2015/11/17 | ||
| - debugging & fixing Verification problems | ||
|
|
||
| Lukas Chrostowski 2015/11/18 | ||
| - removed need for numpy.array | ||
|
|
||
| Lukas Chrostowski 2015/11/19 | ||
