BDD Minimization for Approximate Computing
We present Approximate BDD Minimization (ABM) as a problem that has application in approximate computing. Given a BDD representation of a multi-output Boolean function, ABM asks whether there exists another function that has a smaller BDD representation but meets a threshold w.r.t. an error metric. We present operators to derive approximated functions and present algorithms to exactly compute the error metrics directly on the BDD representation. An experimental evaluation demonstrates the applicability of the proposed approaches
Intelligent Circuits and Systems
ICICS-2020 is the third conference initiated by the School of Electronics and Electrical Engineering at Lovely Professional University that explored recent innovations of researchers working for the development of smart and green technologies in the fields of Energy, Electronics, Communications, Computers, and Control. ICICS provides innovators to identify new opportunities for the social and economic benefits of society.  This conference bridges the gap between academics and R&D institutions, social visionaries, and experts from all strata of society to present their ongoing research activities and foster research relations between them. It provides opportunities for the exchange of new ideas, applications, and experiences in the field of smart technologies and finding global partners for future collaboration. The ICICS-2020 was conducted in two broad categories, Intelligent Circuits & Intelligent Systems and Emerging Technologies in Electrical Engineering
On-the-Fly Layout Generation for PTL Macrocells
Pass transistor logic (PTL) has been recently proposedas an alternative to standard MOS for aggressive circuit design. Even though PTL has been successful in a few handcrafted designs, its acceptance into mainstream digital design critically depends on the availabilityoftools for logic and physical synthesis and optimization. The automatic synthesis of pass transistor circuits starting from BDDs has been intensively studiedinthepast with promising results, but back-end tools for PTL cell generation are still missing. We describe an automatic layout generator that has been designed for seamless integration in a library-free PTL design flow. The generator exploits the distinctive characteristics of pass transistor networks produced by synthesis to achieve quality of results comparable with state-of-the art commercial cell generation tools in a fraction of the execution time
