Dr. Rajkumar Sarma is currently a Research Fellow at Lero, the SFI Research Centre for Software,
at the University of Limerick, Ireland. He completed his PhD at Lovely Professional University,
Punjab, India, in June 2020. Dr. Sarma is currently involved in an Lero platform project called
AutoCircuit, which focuses on developing a machine learning-based system that autonomously
generates digital circuits from user-specified design requirements using a front-end UI. His
research interests include, but are not limited to, Analog and Digital VLSI design, Low-power
architecture design, Quantum Cellular Automata, and FPGA-based prototype development. His
recent work involves designing a Grammatical Evolution (GE)-based synthesizable HDL code
generator and developing an efficient Multiply-Accumulate (MAC) architecture compatible with
IEEE half-precision and single-precision floating-point inputs.
Dr. Sarma has expertise in various Cadence tools such as Virtuoso, Assura, Genus, Innovus, and
Jasper Gold Superlint App. He is also proficient with AMD Xilinx ISE/Vivado tools for FPGA
prototyping on 7-series FPGA boards. He has made significant contributions to the Science
Foundation Ireland (SFI)-funded Automatic Design of Digital Circuits (ADDC) project, achieving
the world's first ML-generated ASIC, prototyped on an FPGA and fabricated using TSMC 65 nm
technology. His responsibilities in the ADDC project included FPGA realization, SPI interfacing,
synthesis, physical implementation using Cadence tools, and functional testing of fabricated
chips.
Dr. Sarma has authored more than 25 research publications in reputable journals and
conferences, including Neural Computing and Applications (NCAA) and CMC-Computers,
Materials, and Continua. His work on multiplier architectures, MAC architectures, and
normalization-based architectures for floating-point arithmetic has been widely recognized in
peer-reviewed publications. Additionally, he has published four books on Hardware Description
Languages (HDL), FPGA prototyping, and other VLSI-related topics. His innovative contributions
to the field are further demonstrated by his numerous patents, covering topics ranging from
compressor-based multiplier circuits to anti-theft security systems for vehicles. Notably, one of
his patents on a Signed Floating Point MAC Architecture (SFMAC) was recently granted by the
Indian Patent Office (IPO).
Dr. Sarma has over 12 years of teaching and research experience. As a supervisor, he has guided
numerous postgraduate theses and undergraduate final-year projects (FYP), leading to
successful research outcomes and subsequent publications. His dedication to student
development is evident in the positive contributions his students have made in the IC design and
testing industry.
