Installation

pip install git+https://github.com/unihd-cag/skillbridge.git

Before you can use the Skill bridge you must generate the function definitions from Virtuoso via the Skill console.

1. Type python -m skillbridge into your shell to acquire the correct PATH-TO-IPC-SERVER
2. Open Virtuoso
3. Type these commands into the Skill console
   • load("PATH-TO-IPC-SERVER")
   • pyDumpFunctionDefinitions "<install>" ("<install>" is not a placeholder, type it as is)

Note: Generating the function definitions is very slow and will take several minutes. Don't cancel the command.

Examples

Note: All these examples assume that the Skill server is running. You can start it by typing the following command into the Skill console.

load("PATH-TO-IPC-SERVER")
pyStartServer

Connecting to the server

from skillbridge import Workspace

ws = Workspace.open()

Accessing the currently open edit cell view

cell_view = ws.ge.get_edit_cell_view()

Inspecting available properties

>>> dir(cell_view)
['DBUPerUU', 'any_inst_count', 'area_boundaries', 'assoc_text_displays', 'b_box', ...]

or type cell_view.<TAB> in jupyter/ipython

Reading properties

>>> print(cell_view.b_box)
[[0, 10], [2, 8]]
