Аннотация
This article explores modern circuit design approaches in digital device engineering, focusing on contemporary schematic, architectural, and technological solutions used in the development of high-performance, energy-efficient, and reliable digital systems. The study analyzes the evolution of digital circuit design from classical transistor–transistor logic and CMOS-based solutions to advanced system-on-chip (SoC), field-programmable gate array (FPGA), and application-specific integrated circuit (ASIC) technologies. Particular attention is paid to the role of schematic design methodologies, modular architecture, and hierarchical design principles in improving scalability, flexibility, and functional accuracy of digital devices. The article also examines the application of modern electronic design automation (EDA) tools and simulation environments that enable designers to model, verify, and optimize circuit behavior at various abstraction levels. Timing analysis, power consumption optimization, signal integrity, and fault tolerance are considered as key aspects of contemporary circuit design. In addition, the paper highlights the importance of integrating low-power design techniques, such as clock gating, power gating, and dynamic voltage and frequency scaling, in response to increasing demands for energy-efficient digital devices.
