4. Combinational Circuit and Sequential Circuit Design using VHDL/Verilog
Combinational and sequential circuits are fundamental components in digital design, with each type serving distinct purposes. Combinational circuits output solely based on current inputs, while sequential circuits incorporate memory and past states in their operations. The chapter delves into designing these circuits using VHDL and Verilog, covering various examples and methodologies for implementation.
