1. A computer-implemented method comprising:
determining, by a machine learning model, a cell layout by:
positioning a first electrical cell and an empty region that abuts the first electrical cell within the cell layout;
generating a first transition cell surrounding the first electrical cell; and
decreasing a width of the empty region; and
providing the cell layout.
