CMOL cell assignment based on dynamic interchange

A new method based on dynamic interchange for cell assignment task of CMOL, a hybrid integrated circuit architecture, is proposed. In this paper, we first transform AND/OR/NOT gates composed of logic circuits into NOT gates and two inputs NOR gates, and then map the NOR/NOT gates to CMOL cells. During mapping process, we first allocate adequate CMOL cell resources and then randomly map the gates to the CMOL cells, which can satisfy the architecture demand and require no overlap between cells. Then we adjust the gates by interchanging and inserting buffers for long distance gate pair. Experiment results on MCNC benchmark show that the proposed approach can result in faster running time than prior approaches¹.
