This paper introduces SiQAD, a computer-aided design tool enabling the rapid design and simulation of computational assemblies of atomic silicon quantum dots. SiQAD consists of several simulation tools: a ground state electron configuration finder, a non-equilibrium electron dynamics simulator, and an electric potential landscape solver for the exploration of field-driven modulation with electrodes. Simulations have been compared against past experimental results to inform the electron population estimation and dynamic behavior. Fundamental logic building blocks and circuits suitable for this platform have been designed and simulated, and a clocked wire has been demonstrated. This work paves the way and provides the first set of open design tools for the exploration of the emerging design space of atomic silicon quantum dot circuits.
