| Abstract(in English) | In this paper, we propose CNFET7, the first open-source cell library for7-nm carbon nanotube field-effect transistor (CNFET) technology. CNFET7 is based on an open-source CNFET SPICE model called VS-CNFET, and various model parameters such as the channel width and carbon nanotube diameter are carefully tuned to mimic the predictive 7-nm CNFET technology presented in a published paper. Some nondisclosure parameters, such as the cell size and pin layout, are derived from those of the NanGate 15-nm open-source cell library in the same way as for an open-source framework for CNFET circuit design. CNFET7 includes two types of delay model (i.e.,the composite current source and nonlinear delay model), each having 56 cells, such as INV_X1 and BUF_X1. CNFET7 supports both logic synthesis and timing-driven place and route in the Cadence design flow. Our experimental results of several synthesized circuits show that CNFET7 has reductions of up to 96%, 62% and 82% in dynamic and static power consumption and critical-path delay, respectively, when compared with ASAP7. In addition, our experimental results of a post-route microprocessor show that CNFET7 has reductions of up to 91%, 66% and 38% in dynamic and static power consumption and critical-path delay, respectively, when compared with ASAP7. |
