Advanced Verilog HDL — Sequential Logic, Counters & FSMs

Welcome to Eddin VLSI Labs — Learn. Design. Verify.Take your Verilog HDL skills to the next level by learning how to design sequential digital circuits, counters, finite state machines, and timing-related components. This course builds on the fundamentals of digital logic and introduces important RTL design techniques used in FPGA and ASIC development.Sequential logic is a core part of digital hardware design. Registers store information, counters track events, finite state machines control multi-step operations, and timing analysis helps engineers evaluate whether a design can operate reliably at its target clock frequency.What you will learnUnderstand registers, latches, and flip-flops and describe them using Verilog HDL.Apply blocking and nonblocking assignments appropriately.Implement synchronous and asynchronous set and reset logic.Design up/down counters, modulus counters, BCD counters, and timer circuits.Understand pulse width modulation (PWM), duty cycle, and counter-based PWM generation.Explore linear feedback shift registers (LFSRs) and feedback logic.Analyze finite state machines, including Mealy and Moore models.Implement FSMs using state registers, transition logic, and output logic.Understand ASM charts and FSM-based applications such as traffic light controllers.Learn button debouncing concepts for reliable digital inputs.Understand setup time, hold time, clock-to-Q delay, and clock skew.Explore metastability and synchronizer circuits.Interpret FPGA timing reports using AMD Xilinx Vivado.Understand clock generation using Vivado's Clocking Wizard.Who should take this course?This course is intended for electronics and electrical engineering students, aspiring RTL design engineers, FPGA developers, VLSI learners, and engineers who want to strengthen their understanding of sequential logic design.Basic digital logic and introductory Verilog HDL knowledge are recommended. Learners should be comfortable reading simple Verilog modules before starting.Learn through practical digital design conceptsThe lectures cover the principles behind counters, PWM generators, FSM-based controllers, sequential circuit timing, and clocking resources.
