### Projects

**BonnCell**- main developer

BonnCell is an automated physical design tool for standard cells and custom transistor-level layouts. Given a set of transistors and a netlist which specifies the electrical connectivity of the transistors, BonnCell computes an area-optimal placement and wiring which is legal with respect to so-called DRC rules. BonnCell is written in C++.
