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.
- Type
python -m skillbridge
into your shell to acquire the correctPATH-TO-IPC-SERVER
- Open Virtuoso
- 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]]
