laygo2.interface.skillbridge module#

This module implements interface with Skillbridge in skill language

laygo2.interface.skillbridge.export(db, filename, cellname, scale=0.001, reset_library=False, tech_library=None, pyserver_id=None)[source]#

Export a laygo2.object.database.Library object to Cadence Virtuoso via skillbridge.

Parameters:

db (laygo2.database.Library) – The library database to be exported.
filename (str, optional) – The path of the intermediate skill script file.
cellname (str or List[str]) – The name(s) of cell(s) to be exported.
scale (float) – The scaling factor between laygo2’s integer coordinats actual physical coordinates.
reset_library (bool, optional) – If True, the library to export the cells is reset.
tech_library (str, optional) – The name of technology library to be attached to the resetted library.

Returns:

str

Return type:

The generated skill script.

Example

>>> import laygo2
>>> from laygo2.object.database import Design
>>> from laygo2.object.physical import Rect, Pin, Instance, Text
>>> # Create a design.
>>> dsn = Design(name="mycell", libname="genlib")
>>> # Create layout objects.
>>> r0 = Rect(xy=[[0, 0], [100, 100]], layer=["M1", "drawing"])
>>> p0 = Pin(xy=[[0, 0], [50, 50]], layer=["M1", "pin"], name="P")
>>> i0 = Instance(libname="tlib", cellname="t0", name="I0", xy=[0, 0])
>>> t0 = Text(xy=[[50, 50], [100, 100]], layer=["text", "drawing"], text="T")
>>> # Add the layout objects to the design object.
>>> dsn.append(r0)
>>> dsn.append(p0)
>>> dsn.append(i0)
>>> dsn.append(t0)
>>> #
>>> # Export to skillbridge.
>>> lib = laygo2.object.database.Library(name="mylib")
>>> lib.append(dsn)
>>> scr = laygo2.interface.skillbridge.export(lib, filename="myscript.il")
>>> print(scr)
