Cross-Section Viewer

Once you are happy with your submitted design, you should use L-Edit's cross-section viewer tool and the process definition file icdc03a.xst to view cross-sections through the cell at various points (e.g. PMOS transistors, NMOS transistors, Vdd rail, GND rail).

Gaining an understanding of how masks relate to the three dimensional structure of your design is one of the most important aspects of this assignment.
