This paper presents a simulator operating on a logical representation of an asynchronous circuit that gives energy estimates within 10% of electrical (hspice) simulation. Our simulator is the first such tool in the literature specifically targeted to efficient energy estimation of QDI asynchronous circuits. As an application, we show how the simulator has been used to accurately estimate the energy consumption in different parts of an asynchronous MIPS R3000 microprocessor. This is the first energy breakdown of an asynchronous microprocessor in the literature
