In this paper. we propose CNFET-OCL. the first open-source cell libraries for 5-nm and 7-nm carbon nanotube field-effect transistor (CNFET) technologies. Our CNFET-OCL is designed to emulate the predictive 5-nm and 7-nm CNFET technologies presented in a published paper. https://countryscenesaddleryandpetsuppliers.shop/product-category/reining-saddle/
