DuplicaTTor® Evaluation Boards from SafeTTy Systems Ltd

At SafeTTy Systems Ltd, our team has particular expertise in the development of reliable, real-time embedded systems using ‘Time-Triggered‘ (TT) software architectures: we help many of our customers employ such architectures as a means of achieving compliance with international safety standards, including IEC 61508 and ISO 26262.

To support organisations that want to explore the use of TT designs in their products we have introduced our first DuplicaTTor® Evaluation Board (DEB).

Using a DEB, organisations can quickly and easily evaluate design options up to ‘SIL 3’ / ‘ASIL D’ level (and equivalent).

We provide further information on DEBs on this page.

Explore TT design options quickly and easily

ERES2 front cover
Using a DEB, organisations can very quickly develop and assess a first ‘proof of concept’ design for their TT embedded system, using the following TT Platforms:.

  • CorrelaTTor-A
  • CorrelaTTor-B
  • DecomposiTTor-B
  • DuplicaTTor-A
  • DuplicaTTor-B

These Platforms are all described in the ERES2 book: as part of the DuplicaTTor package, additional source code and documentation for each Platform is provided, fully ported to the DEB.

As an example, the figure below shows a CorrelaTTor-A design (schematic):

As another example, the figure below shows a DecomposiTTor-B design (schematic):


As a final example, the figure below shows a DuplicaTTor-A design (schematic).




How to order your DuplicaTTor Evaluation Boards


Orders are now being accepted for DEB boards based on 2 x STMF405 MCUs.

These boards are available at a cost of £500 + VAT each (including the specialised DEB TTRDs).

DEBs can be purchased by organisations that either: [i] hold an existing (full) ReliabiliTTy licence, or [ii] join our Taster Day programme.

Please contact us for further information or to place your order.

At this time, we are restricting orders to 10 boards per customer (please contact us if you require larger quantities).

At this time, DEBs are available only to companies based in the EU.



A fully-customised PCB design based on your DEB prototype


Having used a DEB to prove your design concept, you need to know that you can produce a customised hardware design for your product quickly and in a cost-effective manner: working with our Development Partner, we can help you to achieve this.

For example:

  • we can provide DEB designs based on any MCU family that you wish to use;
  • we can add any additional features that you require to an existing DEB design
  • we can provide cut-down designs (with a minimal component count) to match CorrelaTTor, DecomposiTTor or DuplicaTTor requirements.

We believe that our designs solutions are extremely cost effective.

For example, we can make modifications to the standard DEB design (to match your precise requirements) and provide you with a complete set of Altium® Designer files (with a licence to use in production) for a fee starting at approximately £2000 + VAT (including one full day of design work to customise your board).

Please contact us to discuss your requirements (without obligation).



Restrictions on the use of DEBs

At the present time, DuplicaTTor Evaluation Boards (DEBs) are available only to business customers, for use within the EU.

DEBs are intended only for internal research and development (R&D) purposes in the company that purchases the board(s).

DEBs are not designed for (and are not suitable for) use in a product that is released to consumers in any form.

DEBs are not intended to be complete in terms of product safety or environmental measures. Specifically, as they are intended solely for business R&D purposes, DEBs do not fall within the scope of the European Union directives regarding electromagnetic compatibility (EMC), restricted substances (RoHS), recycling (WEEE), FCC, CE or UL, and therefore may not meet the technical requirements of these directives or related directives in other parts of the world.

Purchase of a DEB requires acceptance of these usage restrictions.
