Piotr Bibilo, the founder of the national CAD school, has passed away
03.11.2026
In the 74th year, the life of an outstanding scientist, Doctor of Technical Sciences, Professor Petr Nikolayevich Bibilo, who for a long time headed the logical design laboratory of the United Institute of Informatics Problems of the National Academy of Sciences of Belarus, was cut short.
Pyotr Nikolaevich was born in the Grodno region. His path in science was predetermined from his youth: he graduated from school with a gold medal, the Faculty of Physics and Mathematics of the Grodno Pedagogical Institute named after J. Kupala - with honors. After serving in the ranks of the Soviet Army, he entered graduate school at the Institute of Technical Cybernetics of the Academy of Sciences of the BSSR, with which – in its current status as the United Institute of Informatics Problems – his entire working life was inextricably linked. In 1980, he defended his candidate's thesis, and in 1992 - his doctoral thesis. In 1999, Peter Nikolayevich was awarded the title of professor.
The scientist stood at the beginning of the modern domestic school of automation of digital systems design. His scientific results in the field of logical design theory, synthesis of devices based on ultra-large integrated circuits and functional verification have received recognition far beyond the borders of Belarus.
He developed methods of Boolean functions and systems based on the solution of logical equations, methods of decomposition of interval forms of systems of Boolean functions and binary diagrams of solutions, methods of optimization and synthesis of digital devices based on configurable and programmable structures, generalized the method of Shannon-Povarov cascades to the case of interval forms of systems of Boolean functions and finite predicates, as well as a mutually agreed set of languages that allow supporting the process of end-to-end design of the control logic of custom digital SBIs, and "silicon compilation" information technology for functional blocks implementing control logic.
Pyotr Nikolayevich became the initiator of the introduction of the VHDL language into the domestic engineering practice - the international standard for the description of hardware. He has published five monographs on this technology, including the repeatedly reprinted book "Synthesis of logic circuits using the VHDL language."
The result of his many years of research was a series of fundamental monographs: "Synthesis of combinational PLM structures for SBIs", "Silicon compilation of custom SBIs", "Decomposition of Boolean functions based on the solution of logical equations", "Application of binary choice diagrams in the synthesis of logic circuits" and "Logical design of discrete devices using the production-frame model of knowledge representation" (co-authored with V.I. Romanov).
Pyotr Nikolayevich supervised the implementation of dozens of projects and tasks of the State Research Programs, State Scientific and Technical Programs, tasks of the Union State Programs, projects of the Belarusian Foundation for Fundamental Research
Bibilo P.N. - the author of more than 400 scientific works, 10 monographs and four textbooks. His textbook "Fundamentals of the VHDL Language" was published 10 times, and the collection of tasks for designing logic circuits - 5 times. In 2005, he initiated the creation of the first Russian-language site dedicated to the VHDL language. On the basis of his developments, the SCAS software complex was created, which at the time of its appearance was the best design system in the CIS countries.
Pyotr Nikolayevich generously shared his knowledge. He prepared eight candidates of sciences, supervised master's and dozens of theses, taught for many years at the Belarusian State University and the Belarusian State University of Informatics and Radioelectronics.
His authority in the scientific community was undisputed: he was the chairman of the organizing committees of seven international conferences "Computer-Aided Design of Discrete Devices", a member of the expert council of the Belarusian Academy of Sciences (for more than 15 years), a member of the doctoral council, the editorial board of the journal "Informatics" and the expert council of the Ministry of Industry of the Republic of Belarus.
The work of Petr Nikolayevich Bibilo was highly praised by the state and the scientific community. He was awarded the Francis Skoryna medal, the National Academy of Sciences of Belarus prize, jubilee medals "In honor of the 80th anniversary of the National Academy of Sciences of Belarus" and "In honor of the 90th anniversary of the National Academy of Sciences of Belarus", certificates of honor of the National Academy of Sciences of Belarus and the National Academy of Sciences of Belarus, as well as a scholarship of the President of the Republic of Belarus.
For his colleagues, Pyotr Nikolayevich was an example of scientific rigor and dedication to work, for his students - a guide in the profession.
The bright memory of Pyotr Nikolayevich Bibilo will forever be preserved in the hearts of his relatives, friends, colleagues and thousands of students for whom he opened the way to greater science.
