Utilizing unspecified input states to achieve further circuit minimization. 4. Combinational Logic
NAND and NOR gates, which can replicate any other logic function. A tabular method for larger, more complex logic minimization
Unlike pure theory books, Tan’s notes include references to actual hardware description languages (usually Verilog). He shows you how a case statement in Verilog maps to a MUX, and how an always @(posedge clk) maps to a D-Flip-Flop.
Sequential circuits rely on both current inputs and previous states. They require storage elements (memory) and are usually controlled by a clock signal. Seeing a circuit blink or count in real-time
One night, preparing for a design review, Aaron discovered a subtle timing hazard in a synchronous sequential circuit illustrated in the PDF. Two signals raced across different paths and arrived at a gate slightly offset, creating a glitch that briefly produced the wrong output. He imagined the gates as runners on different lanes, and the glitch as a fumbled baton. To fix it, he inserted a small synchronizer—a pair of flip-flops—to align the runners’ arrivals. When the waveform settled cleanly, he felt a satisfaction like closing the final page of a novel.
