Welcome to the NANOxCOMP Project

Nano-crossbar arrays have emerged as a strong candidate technology to replace CMOS in near future. They are regular and dense structures, and fabricated by exploiting self-assembly as opposed to purely using lithography based conventional and relatively costly CMOS fabrication techniques. Currently, nano-crossbar arrays are fabricated such that each crosspoint can be used as a conventional electronic component such as a diode, a FET, or a switch. This is a unique opportunity that allows us to integrate well developed conventional circuit design techniques into nano-crossbar arrays. Motivated by this, we aim to develop a complete synthesis and performance optimization methodology for switching nano-crossbar arrays that leads to the design and construction of an emerging nanocomputer.
Project objectives are 1) synthesizing Boolean functions with area optimization; 2) achieving fault tolerance; 3) performing performance optimization by considering area, delay, power, and accuracy; 4) implementing arithmetic and memory elements; and 5) realizing a synchronous state machine.

Project by the numbers, 2015-2019
Started in 2015, the project has been successfully completed in 2019 with many achievements including:
- 1.300.000 TL/$450.000 was received to be spent for our group. $300.000 came from an EU H2020 project and $150.000 came from three different TUBITAK projects. We are the principal investigator (PI) of all these 4 projects.
- 20 peer-reviewed papers were published/accepted. 13 of them are solely made in ECC -- all authors are from our group. 4 of them are coauthored by our collaborators from industry and 5 of them are coauthored by our collaborators from academia.
- 5 Masters students graduated from our group and 5 Doctoral students joined us.
