KEY FEATURES
Photonic Design
Create your PIC design with significant productivity improvement using either a schematic driven or layout first design methodology both using automated waveguide routing.
Layout Only Design
- Create a PIC design in an IC layout editor
- Using drag and drop or a script driven methodology
- Use foundry supplied components, user developed or some combination
- A simulation netlist can be created as input to our photonic simulation partners
Simplifying Photonic Layout
- Simple waveguide creation and editing
- Automated crossing insertion
- Precision snapping to optical pins
- Wave guide to pin checking
Complete PIC Design Flow
- Photonic layout verification with Calibre's equation based design rules
- Photonic simulation is supported though integration with our partners
- Simulation partners are Optiwave, VPIphotonics and Lumerical
- Photonic PDKs are available from multiple foundries
- Scriptable with Python
- L-Edit Photonics is available on both Linux® and Windows®
Layout Creation
- Quickly create a ready for simulation PIC layout
- Place devices, like schematic or individually
- Autoroute waveguides, targeting the lowest loss
- Waveguides can also be created manually
- The user can use foundry supplied devices, user created or some mixture of both
- Autoroute or manually make the electrical connections
Routing Directives
- If loss information is available in the PDK, the router will create the waveguide with the lowest loss
- The user can apply routing directives to the waveguides
- Fixed length
- Same length
Waveguide Editing
- Autorouted waveguides can be edited
- Minor changes are made using stretch handles
- Larger changes convert the waveguide back to a wire, make the change, and convert back to a waveguide
- Active device placements can be moved and the waveguide is updated
- Waveguides are constructed using foundry, user provided or some combination Pcells
Preparing for Verification
- The waveguides are annotated back to the schematic
- A new level of hierarchy is created in the original schematic. The waveguide components are oriented identically as they are in the layout
- Netlist are exported based on the foundry simulation requirements – transistor or photonic specific simulators
- LVS netlist can also be exported from the schematic
Layout First
- Place the optical components
- Then the components are autorouted or connected manually
- If a schematic is needed in order to get a netlist for simulation, the schematic is automatically created, It will look identical to the layout
- Then both simulation and LVS netlists can be exported
