PLEASE NOTE: This is a LIVE INSTRUCTOR-LED training event delivered ONLINE.

It covers the same scope and content as a scheduled face-to face class and delivers comparable learning outcomes. Daily sessions comprise 4-6 hours of class contact time.

Essential Digital Design Techniques is a fast-track, application orientated course designed to bridge the gap between text book theory and real world digital design practice.

It significantly accelerates the on-the-job learning curve for engineers new to digital design, or those needing to refine their design skills before project involvement. With a strong emphasis on practical design and hands-on workshops, this course has been specifically developed to capture design techniques usually learned over months, in an intensive 4-session format.

Essential Digital Design Techniques provides the ideal first stage in full scale project training for graduate design engineers, or engineers moving into digital design from other disciplines (including software or analog design). As such, it is the natural precursor to the Doulos Comprehensive VHDL and Comprehensive Verilog courses, which prepare engineers for HDL application within FPGA or ASIC design projects.

Who should attend

  • New graduate engineers embarking on a first project, or engineers with limited practical experience of digital design.
  • Engineers from other disciplines (e.g. software design or analog design) re-training for digital design involvement, or requiring familiarisation with modern digital design techniques.


A secondary/high school level understanding of electrical circuits is the only pre-requisite for this training. Delegates require no prior involvement in digital design projects or HDL knowledge.

What you will learn

  • Basic principles of digital logic design and how they are applied to real world applications
  • Combinational and Sequential Logic Design for PLDs and ASICs, with an emphasis on synchronous design techniques
  • How to design and implement fundamental structures e.g. decoders, multiplexers, shift registers, counters
  • How to design and implement synchronous Finite State Machines
  • An overview of ASIC and field programmable logic design, including design practices for state of the art devices
  • Designing with programmable devices
  • Effective Design methodologies and flows, including an introduction to the principles of design using Hardware Description Languages

this course does not teach, or require knowledge of a specific Hardware Description Language.
