Training advanced VHDL

Advanced VHDL

The advanced VHDL training is meant for designers who work some time with VHDL (designers, but also for engineers who describe test environments). During the training, where theory and practice will vary, the base knowledge will be refreshed and afterwards the less known aspects of VHDL will be considered. Trainees will work on their own case. For this case, alternative descriptions will be discussed about the pro's and con's for simulation and synthesis.

  • Intensification in VHDL (simulation and synthesis), a.o
    • Simulation model
    • Waveforms, transactions, guarded signals (bus, register), (disconnection of) drivers
    • Delay mechanisms
    • File IO (formatted and text)
    • Overloading, qualification
    • Protected types, shared variable
    • Resolution function
    • Impure/pure functions
    • Implicit signals
  • Introduction Verilog. Often a VHDL user will get in contact with Verilog, e.g. when a synthesis tool generates Verilog output. Also co-simulation of VHDL and Verilog occurs.
  • VITAL (VHDL Initiative Towards ASIC Libraries) enables post simulations with a VHDL simulator, with the 'real' delays of hardware. This enables automatic control for timing constraints. Although it was intentionally meant for ASIC's, it is now a commodity for FPGA's.
  • PSL (Property Specification Language). With the increasing complexity of designs, the need for different verification methods increases. For the hardware description languages, there has been chosen for PSL; an IEEE standard. Nowadays, a lot of VHDL simulators support (embedded) PSL.
  • Choices have been made to give the training to a relatively small group of students. This give the ability to change the training on the fly. For instance, some more attention can be given to :
    • VHDL-AMS (Analog Mixed Signal). A superset of VHD, which enables the creation of analog models. This has been used in the automotive industry!
    • State machines (part of Fundamentals & Synthesis training).
    • Numeric_std (part of Fundamentals & Synthesis training)


The training is very suitable for those who have worked some time with VHDL (as a designer, but also for test engineers who describe test environments). The training is less suitable for the beginning VHDL user. For them, the training Professional VHDL would be better.


The training has been given by B. Molenkamp, teacher of the faculty Elektrotechniek, Mathematics and Informatica of the Universiteit Twente. He is a VHDL trainer at Dizain-Sync B.V. since 1989.


The training will take 2 days.


Training center of Dizain-Sync, Borne. On-site Courses is on request.
