Specify WG length

[lukasc-ubc]

Once drawn, give user ability to type in a length, and have waveguide adjust itself.

Add Length as parameter in waveguide PCell. Gettable & Settable.

Works but needs improvement. There are some bugs eg. sometimes the layout disappears upon the completion of the resizing operation.

press Ctrl + Shift + R to run the script while having a transient selection.

Hi Jaspreet,

A few problems:

• Layout disappears. I've seen this before when using a GUI and performing operations. In my case, the solution was to close the GUI first, then perform layout modifications
• if you select the waveguide, it crashes. only works if you select the path. should work for both. see my script "Waveguide_to_path"

Suggestions:

• remove 1st and last segments; these presumably never will be useful.
• perhaps only list eligible segments: name those whose neighbour segments point in the same direction (middle of a U-shape being the only allowable one).

Other:

• i edited the script: message text change, and added to menu.

fixed:

• layout disappears
• selection for PCell vs. GUIDING_PATH; both work
• correctly measuring the path length including bends
• added Undo functionality
• removed 1st/last points.

to do:

• quality control checking
• perhaps only list eligible segments: name those whose neighbour segments point in the same direction (middle of a U-shape being the only allowable one).

Bug:

• if the segment to be moved is on the left, it applies the "diff" in the incorrect direction (makes the waveguide shorter instead of longer)

[jaspreetj]

working on the Bug and to do items.

[jaspreetj]

Fixed: if the segment to be moved is on the left, it applies the "diff" in the incorrect direction (makes the waveguide shorter instead of longer)

New Bug detected: Waveguide resizer does not work on a waveguide which has already been resized. It moves the waveguide to the origin(0,0).

Currently Working on it.

Bug: segment says "horizontal" but it is vertical.

[lukasc-ubc]

did some GUI improvements.

[jaspreetj]

The script was giving me syntax errors. So I did following fixes.

I commented out the line no. 110.

and changed line no. 79 from
if len(o_selection)<>1:
to
if len(o_selection)< 1:
