  • Hi Matthias, Something changed for me in the behaviour of "PCell content is selectable (Caution: PCell recomputation may conflict with edits)". Previously (up to a couple of days ago, perhaps after I reset my klayoutrc file), I operated …
    in PCell contents not selectable Comment by lukasc November 2015
  • Thank you David. I confirm that undo/redo works. However, I also confirm the bug you found. Another thing I found is that if you don't call "commit", you have a problem: * The layout screen goes empty, and I can't see the box. The Cell…
    in Adding Undo/Redo for script-based actions Comment by lukasc November 2015
  • Hi Matthias, I implemented a netlist extraction, and posted the code on GitHub - https://github.com/lukasc-ubc/SiEPIC_EBeam_PDK It searches for paths and ROUND_PATHs, finds out what they are connected to, and generates a Spice netlist file. Then …

  • Good point. It makes sense to use microns for PCells.
    in "path" in ROUND_PATH, via script, not in dbu; DPath to Path, DPoint to Point Comment by lukasc November 2015
  • I didn't notice, but the "path" is actually a DPath object, which includes the parameter "w". So I can read this in order to write an "undo" ROUND_PATH function.
    in Round_path PCell in python, create_cell Comment by lukasc November 2015
  • Thanks Matthias and David. I think I figured out a way to implement the follow functionality. (updated on GitHub) I have two hotkeys: * W: snaps the path to the nearest pins, and uses the ROUND_PATH to make it a waveguide. Keep track of which pi…
    in Object callbacks, connected objects following each other when moving Comment by lukasc November 2015
  • Hi Kazzz, You're right, it works. I guess I'll start from scratch and re-enter my preferences...
    in Drag and Drop to open files, OSX Comment by lukasc November 2015
  • Hi Matthias, Re - crashing. Yes, they occur during self.register, while developing PCells. The following crash occurred after I copied and pasted a PCell in the code, renamed it, (didn't add a new register_pcell line) and ran the script. Also, I…
    in Python, nesting PCells Comment by lukasc November 2015
  • Got it, but still experiencing the key binding problem. My key bindings: https://www.dropbox.com/s/vebf3k0vxvzoods/Screenshot%202015-11-13%2003.38.01.png?dl=0 Same problem. When I push "x" or Shift "x", nothing happens. Same …
    in Drag and Drop to open files, OSX Comment by lukasc November 2015
  • Thank you. The latest version on klayout.de is 0.24.2, and your Dropbox link is 5 days old: https://www.dropbox.com/s/73v7uelklbcjvr8/klayout-0.24.3-MacOSX-Yosemite-1-Qt487mp.dmg.bz2?dl=0 I downloaded this, and confirm that the DRC is fixed! How…
    in Drag and Drop to open files, OSX Comment by lukasc November 2015
  • Thanks Kazzz! Here's another minor "bug". The Key Bindings don't seem to work for the toolbar objects. For example, edit_mode.mode_menu.instance, Instance – setting this to "i", and pressing "i" doesn't do anything. …
    in Drag and Drop to open files, OSX Comment by lukasc November 2015
  • How do you get the width of the path from the ROUND_PATH PCell? Here is the list returned for the PCell: * def PCell_get_parameter_list ( ROUND_PATH, Basic): * Name: layer, TypeList, unit: , default: None, description: Layer. * Name: radius, T…
    in Round_path PCell in python, create_cell Comment by lukasc November 2015
  • It seems like I can just scale the values returned by the PCell "ROUND_PATH" DPath = subcell.pcell_parameters_by_name()["path"]*(1/dbu) # DPath object and get it back to dbu rather than microns...
    in "path" in ROUND_PATH, via script, not in dbu; DPath to Path, DPoint to Point Comment by lukasc November 2015
  • Thanks Matthias. My main objective was to understand how to call the layout generation function from PCells in general (including my own). I agree that the circle is simple so make more sense to code in yourself. Yes, the ROUND_PATH functionality…
    in Round_path PCell in python, create_cell Comment by lukasc November 2015
  • 1) In the above example, the code isn't quite right. It should be cell.flatten(True). It flattens everything under cell, namely the fake text_cell. But... I notice that all the flatten functions you have flatten all the contents of the cell, but…
    in Python, nesting PCells Comment by lukasc November 2015
  • One more attempt to fix this, using coerce_parameters. The documentation states that "The reimplementation may modify the parameters in a way that they are usable for the produce method", so I hoped it would fix the parameters... pcell_d…
    in Round_path PCell in python, create_cell Comment by lukasc November 2015
  • Hi Matthias, I am able to get the create_cell and cell.insert approach for PCell instantiation to work on: * my PCell (based on your example, Circle), * Basic.TEXT * Basic.ROUND_PATH But it doesn't work for: * Basic.CIRCLE * Basic.DONUT Specifi…
    in Round_path PCell in python, create_cell Comment by lukasc November 2015
  • Hello Matthias, I notice that the GUIDING_SHAPES layer is always black, and doesn't show up in the Layers palette. Is there any way to add it there, so we can toggle visibility, select-ability, color, stippled, etc?
    in PCell guiding shapes are 'active' even when hidden Comment by lukasc November 2015
  • I noticed that the ROUND_PATH expects a DPath object instead of Path. And also I had to take out the dbu part (looks like the path units are in microns already) So I tried that instead: a1 = []for p in points: a1.append (pya.DPoint(p[0], p[1]))w…
    in Round_path PCell in python, create_cell Comment by lukasc November 2015
  • great, thank you. this also lets you edit the geometries... eg. delete polygons. but when you save & reload the layout, the PCell is regenerated
    in Show Vertices for PCells Comment by lukasc November 2015
  • I ended up creating the following function, and calling it from a PCell: def layout_pgtext(cell, layer, x, y, text, mag): # example usage: # cell = pya.Application.instance().main_window().current_view().active_cellview().cell # layout_pgt…
    in Python, nesting PCells Comment by lukasc November 2015
  • I have the basics working, namely using a function to create the layout within a PCell. I also got the polygon text working, however I have a concern about the "fake PCell" trick. Doesn't that just create a new cell each time the PCell c…

  • fantastic. the "def produce_A(layout, x, y, ...):" approach sounds great.

  • Thanks Kazzz!
    in DRC crashing Comment by lukasc November 2015
  • Hi Matthias, I also have an interest in this. Since we are using Paths for both electrical connections, and for optical waveguides (using Convert to PCell | Basic.ROUND_PATH functionality), I wonder if something could be done by simply reading d…
    in Netlist extraction via "Trace Net" Comment by lukasc November 2015
  • Hi Matthias, The problem still exists in the the latest binary on OSX, 0.24.2. I know some of my students were able to get it to work (presumably on Windows). Here's the crash report. Though now the app doesn't close, but rather brings up useful…
