The increasing complexity of digital systems has led to the development of new design methodologies and tools. This paper presents an overview of modern digital design flows using Electronic Design Automation (EDA) tools, VHDL (VHSIC-HDL), and Field-Programmable Gate Arrays (FPGAs). The paper covers the design process, EDA tools, VHDL language, and FPGA technology, highlighting their applications and benefits in modern digital system design.
