VHDL-AMS Modeling Training

Today’s Challenges

Systems-on-Chip (SoC) and systems integrate more and more analog and mixed-signal blocks. Proven top-down design methods for pure digital circuits can not be applied directly to mixed-signal designs where bottom-up design flows are generally used for analog components. Behavioral models implemented in VHDL-AMS enable the designer to apply a top-down approach also for analog and mixed-signal designs to benefit from advantages such as:

  • delivering an executable specification at an early design stage,
  • enabling verification and optimization runs over the whole system in a mixed-signal simulator,
  • increasing simulation speed using behavioral models of selected components of the system.
VHDL-AMS also eases the modeling and, therefore, the simulation of multi-domain systems including both electrical and mechanical, thermal, hydraulics, and/or magnetic models.

Who should attend this training?

This seminar is intended for designers involved in mixed-signal electrical designs and/or analog behavioral modeling and simulation.

Why should you attend?

The optimal usage of an analog and mixed-signal language is complex since it does not only describe the model behavior itself, it also provides language constructs or commands for the simulation synchronization between signal domain (event driven) and electrical domain (time continuous) entities. Having the necessary knowledge of mixed-signal simulation is crucial to succeed in modeling mixed-signal designs. The training teaches you the techniques enabled by the VHDL-AMS language to master the modeling challenges in this field.
By attending this training, you will:

  • Acquire the fundamental knowledge of the VHDL-AMS language
  • Apply multiple modeling techniques (behavioral, structural)
  • Understand the mixing of VHDL-AMS capabilities in otherwise pure logic HDL models!
  • Identify which applications benefit from a VHDL-AMS implementation
Additionally, when creating a behavioral model for a specific device, there are many possibilities depending on the characteristics which need to be modeled. Therefore, designers must master the concept of equivalence classes presented during the training.
All practical exercises will be performed with SMASH, the simulator offering the best coverage of the VHDL-AMS standard.


  • Basic knowledge of the modeling functionality of some electrical components (Resistor, Diode…)
  • Basic knowledge of VHDL

Practical information

This training lasts 2 days during which theoretical information will be illustrated by one or several examples. It can be led either in English or in German. Snacks, lunch and coffees are offered to the trainees.
