If you run
Simulation>Show Compact Model in Lumerical Interconnect

and then Cancel it from the confirmation menu, the simulation still goes through.

We have already done this before a few years ago (gds2fdtd); it needs to be integrated / redone.

Create a compact model using 3D-FDTD:

• auto export the GDS for the selected device.
• configure FDTD using GDS, and DevRec and PinRec.
• run single simulation using from selection: user can verify it is working
• run sparam simulation plus corners
• save data into a Lumerical CML as a custom device

Waveguide hotkey should not show GUI, instead use 'current configuration'

This means GUI parameters must be initialized BEFORE gui.show()

On Windows, when I change the display configuration "change the size of all items", e.g., 200%, the GUI for Waveguides gets messed up.

All the other KLayout GUIs are fine.

Do we need a development branch for SiEPIC-Tools? Can we just use master?

Right now, master is the old one (essentially 0.2.0) and not working..

Limitation in Verification: we assume that the layout was created by SiEPIC-Tools in KLayout, that PCells are there, and that the layout hasn't been flattened. This allows us to isolate individual components, and get their parameters. Working with a flattened layout would be harder, and require:

• reading parameters from the text labels (OK)
• find_components would need to look within the DevRec layer, rather than in the selected cell
• when pins are connected, we have two overlapping ones, so detecting them would be problematic. This could be solved by putting the pins inside the cells, rather than sticking out. But that requires a change in all PDKs and in Tools on how pins are defined in the code.

Hi Brett,

I discovered that you introduced a bug in the arc function, when you changed it. Namely the arc wasn't stopping exactly at the correct angle. This would introduce tiny gaps between arcs that are supposed to be connected. Did CMC find DRC errors in your layouts, with small gaps?

Anyways, I spent a long time debugging, and more or less returned it to what it was before...

Can you check your functions / PCells that rely on it to make sure it still works for your cases?

Action class cannot be reassigned, throws an exception, submitting a bug to KLayout.

Implement empty function in examples.py

Example that can be used as reference:
https://github.com/bpoulse/SiEPIC_EBeam_PDK/blob/master/klayout_dot_config/pymacros/Layout%20-%20IME%202017.lym

Convert previous generate_short_spice_files() function netlist trimming into:

# Inputs, and example of how to generate them:
# nets, components = topcell.identify_nets()
# selected_component = components[5]   (elsewhere the desired component is selected)
def trim_netlist (nets, components, selected_component)
  return trimmed_nets, trimmed_components

Presently it is a Lym file within each PDK. Presumably it should be shared.

Working on moving to pymacros in SiEPIC-Tools (dev branch)

When converting a waveguide to a path, the width of the waveguide should be read from the PCell and passed on to the new path. (implementation is in EBeam v0.1.x).

When used in the following PCell instead of layout_arc_wg_dbu , i'm seeing the following:

This error also occurs when called for any other technology

Check that all pins are connected

After installing via Packages, import SiEPIC didn't happen. Screenshot:

would be useful for debugging for component makers

pin rec, text, etc...

and pin direction so that they are leaving the component.

Change from full path to relative

@jaspreetj (perhaps?)

I have it working on Mac OSX. Could someone get this working for Windows?

See SiEPIC.lumerical.interconnect.Setup_Lumerical_KLayoutPython_integration() and SiEPIC.lumerical.interconnect.launch()

thank you

Actual form is implemented using ui file. Needs logic.

For MC script, only get_parameters etc must be called

I understand the use of py files, since you can import them. But the debugger and "singleton-like" behaviour means we need to exit KLayout each time changes are made to py files.

Can we minimize the use of py files?

Lym files work well in the debugger where you can see the error, breakpoints, etc.

• check if TE label is inside a TE GC cell, and TM inside TM.
• add valid GCs list to the DFT.xml file.

Has anyone noticed an issue with PCells in KLayout 0.25 like below?

When inserting a new PCell, the instance does not show up in the hierarchy where it has been placed. In this example, I tried to add a Lumerical Laser to the cell v1.

Created a new menu: Measurement Data. Fetch data from GitHub and plot. Working on OSX/Windows, but presently only downloads the files and opens the PDFs.

Need a GUI to:

• filter by fabrication foundry, etc.
• select files: ctrl-click to select multiple ones (e.g., device fabricated several times, resulting in an overlaid plot)
• plot using INTERCONNECT (or directly in KLayout if possible)
• measurement versus simulation: simulate the selected opt_in and add to the plot

I don't what changed. But yesterday the hotkeys were working, and were automatically loaded.

Sometime tonight they stopped. Have to run manually "SiEPIC installation and initalization", each time a new layout is created or a new GDS file is loaded.

Data structure that can be used for various verification functions and netlist creation

ENHANCING core.py => Class Map

Using generated netlist, create spice file

Launch an INTERCONNECT simulation using the opt_in label:

• user-selected opt_in
• find closest GC
• extract the trimmed netlist
• read simulation parameters from opt_in label and perhaps additional data (CML's wavelength range for each component in the circuit, or configuration for the edX course laser sweep).

• Change LayerInfo list to actual names
• Change offset/slot to subtraction
• Guiding shape fix
• Waveguide to path should read path width from PCell

When attempting to setup INTC CML (for any package) in kLayout, I see the following:

Syntax error. Hence the SiEPIC configure shortcut keys menu item isn't appearing.
