Course TTb: The Engineering of Reliable Embedded Systems (online)


Course TTb has a focus on the use of ‘Time-Triggered‘ (TT) architectures to support the development of software for safe and reliable embedded systems.

  • TTb can be delivered on your company site (anywhere in the world) on dates of your choosing;
  • TTb is available as a self-paced online training module: we describe the online course on this page.

Who should take this course?

Course TTb covers the core techniques that are needed to design and implement TT software for use in safety-related embedded systems.

  • Taking Course TTb will be of particular benefit to organisations that need to develop software for embedded systems in compliance with international safety standards, such as IEC 61508, ISO 26262, DO-178C, IEC 62304, ISO 13849, IEC 60335 and IEC 60730, up to ‘SIL 3’ / ‘ASIL D’ level or equivalent.
  • Taking Course TTb will be of particular benefit to organisations that are ReliabiliTTy® licensees (or to organisations that are intending to become ReliabiliTTy licensees).

Course TTb discusses technology that is patented by SafeTTy Systems Ltd and is subject to copyright and other restrictions.

The techniques discussed in Course TTb, the public TTRDs downloaded from this website and the designs and techniques documented in the ERES book series may be used without charge: [i] by universities and colleges in courses for which a degree up to and including “MSc” level (or equivalent) is awarded; [ii] for non-commercial projects carried out by individuals and hobbyists.

Use of the techniques and code examples described in Course TTb or the ERES books in any commercial project (including training courses) or in university research projects (including PhD-level programmes and equivalent) requires purchase of a ReliabiliTTy® Technology Licence.

Please contact us if you have any questions about these licence arrangements.

The benefits of online training

empty_space
Since 2014, we’ve delivered our popular on-site TTb course to many organisations across the world: so far, we’ve introduced around 200 engineers to the use of TT software architectures in safety-related systems by means of this 3-day course, with a class size of around 6 people being typical.

We appreciate that for individuals and small teams, on-site training can be a little expensive. We also appreciate that it can be difficult for any organisation to have their whole development team attend a training course at the same time.

To address these problems, we introduced an online version of our TTb course as a flexible and cost-effective alternative to on-site training.

The online TTb course is based on a series of 28 videos (almost 10 hours in total).

The first video is freely available (see below).

As with the on-site course, the content of the videos follows the ‘ERES2‘ book closely.

Is there a registration process?

empty_space

To get started, there is no formal registration process.

All you need to do is buy a copy of the ‘ERES2‘ book and the TTb Course Notes, and then sign up for our Vimeo channel.

The videos and associated course notes will then guide you through the material presented in the ERES2 book, at your own pace.

How to prepare for your on-line course

empty_space

To prepare for course TTb, we suggest you purchase the ‘ERES2’ book and course notes, but delay the start of your Vimeo subscription until:

  • these items have been delivered; and,
  • you have read the first two chapters in the book.

If you find the material in the book challenging, you may like to view out TTa videos before you proceed (these videos are freely available).

We also provide some information on our ‘Getting Started‘ page that may be useful.

How long does it take to complete TTb online?

empty_space
We estimate that – following any preparation period – completing the TTb course will take 1-2 months on a part-time basis (we suggest you allow around half a day – 4 hours – per week while you are studying).

Support and examination option

safetty_certified_logo3_201

The standard TTb online training package:

  • does not include exercises or any form of one-to-one support for course participants; and,
  • is not intended to meet the full requirements for completion of Level 2 in the SafeTTy Certified programme.

If you have a team of 4+ people that wishes to complete the Level 2 exams, we suggest that you consider an ‘on-site’ course.

For individuals and teams of less than around 4 people that wish to complete the Level 2 exams, we can offer a 2-month support package (with exam by Skype®) for an additional fee of £850 + VAT (per person).

This add-on package provides you with an online tutor (who will provide support by email during your course): this will allow you to ask questions about the course material. You will also be provided with a set of six exercises to help you to prepare for the Level 2 exam: support for (and feedback on) the exercises will also be provided by email. The cost of the exam itself (a technical interview, conducted via Skype over a period of 1-2 hours) is included. If successful in the exam, this package also covers the cost of your training certificate (and delivery of this certificate by post).
