ReliabiliTTy® Technology Licences
In order to support organisations that wish to develop ‘Time Triggered‘ embedded systems in compliance with international safety standards, we offer a range of cost-effective ReliabiliTTy® Technology Licences (RTLs).
Further information about RTLs is provided on this page.
The majority of our customers purchase their RTL as part of a cost-effective SafeTTy Solutions™ package.
[This page was lasted updated: 2018-06-15]
RTLs allow use of the technology and ‘Time-Triggered Reference Designs‘ (TTRDs) described in the ‘ERES2‘ book (including all technology patented by SafeTTy Systems Ltd) in sectors ranging from aerospace, automotive, medical and industrial systems through to household goods.
RTLs also provide access (free of charge) to our growing collection of RTL TTRDs. In many cases, our customers develop their application software by building on an RTL TTRD, supported by training and / or consultancy services from our team. The combination of this advanced code framework and highly-experienced support can significantly reduce the development effort (and time) required to create a safe / reliable / secure TT design and achieve compliance with international safety standards.
At the present time, RTLs allow use of the following patented technology (under the terms of the customer’s specific RTL):
- Pont, M.J. (2017) “A framework as well as method for developing time-triggered computer systems with multiple system modes”, SafeTTy Systems Ltd, US Patent No. 9,830,211.
- Pont, M.J. (2016) “A monitoring unit as well as method for predicting abnormal operation of time-triggered computer systems”, SafeTTy Systems Ltd, GB2526082.
- Pont, M.J. (2016) “A framework as well as method for developing time-triggered computer systems with multiple system modes”, SafeTTy Systems Ltd, GB2526083.
Further patents have been applied for.
We offer ReliabiliTTy licences in three categories: RTL0; RTL2 and RTL4.
The categories are related to a maximum ‘Safety Integrity Level’ (SIL) – or equivalent – of the projects in which the licences may be applied.
A summary of the links between licence categories and SILs is given in the table below.
- RTLx licensees can work with microcontrollers from any manufacturer.
- RTLx licensees can work with compilers and other software tools from any manufacturer.
- All licence categories (RTL0, RTL2 and RTL4) allow use of the recommended TT Platforms described in the ‘ERES2‘ book (CorrelaTTor®, DecomposiTTor®, DuplicaTTor®). This means (for example) that an RTL0 licensee could use a CorrelaTTor or DuplicaTTor platform (in a design that was not safety related), if such a platform was felt to be an appropriate solution for the product in question.
- RTL0 licences are typically purchased in order to allow use of the techniques and code presented in the ‘PTTES‘ book and / or ERES2 books in commercial projects that do not have safety implications.
The above notes are intended to summarise some of the key terms of RTLx icences: please also consider the information provided below and contact us if you have any questions about these licence arrangements.
We offer Evaluation Licences, Product Licences, Site Licences and Custom Licences.
ReliabiliTTy Technology Evaluation Licences (RTELs) allow organisations to explore the potential benefits of a full Reliability Technology Licence by carrying out detailed prototyping or evaluation activities. However, RTELs do not allow organisations to sell or give away products based on any technology or code examples described in the ERES book series.
ReliabiliTTy Product Licences allow the design, manufacture and sale of a single identified product that incorporates ReliabiliTTy technology.
ReliabiliTTy Site Licences allow the design, manufacture and sale of multiple products that incorporate ReliabiliTTy technology in a single location.
ReliabiliTTy Custom Licences support more complicated requirements, including design and manufacture across multiple locations.
Please contact us for further information.
Fees for RTELs are £5,000 + VAT for a 24-month site licence. While their RTEL is ‘active’, organisations have access to our collection of RTL TTRDs (which may be used for evaluation purposes, as detailed above).
Fees for RTLs start at £5,000 + VAT for a single product (RTL0), and £25,000 + VAT for a site licence (RTL0). RTLs are usually permanent and always royalty free.
Most of our customers purchase their RTL as part of a cost-effective SafeTTy Solutions™ package.
Please contact us for further information about licence fees.
Distributing product designs based on RTLs
Rights obtained through the purchase of RTLx Site Licences are not transferrable.
To explain what this means, suppose that your organisation owns an RTL4 Site Licence. Further suppose that your organisaton develops a system / product on behalf of a different organisation (we’ll call it “Organisation X”), and that this system / product incorporates technology that has been provided to you under the terms of the Site Licence.
If Organisation X has the right to sell the system / product that you developed in their own name, then Organisation X will require an appropriate RTL (for example, an RTL4 Product Licence).
One option in these circumstances is that your organisation could purchase an RTL4 Product Licence on behalf of Organisation X.
Please contact us if you have any questions about these arrangements.
Use of ReliabliliTTy technology in defence systems
By default, we do not provide RTLs for use in defence systems.
The use of any products and technology in defence systems may involve discussions with the relevant authorities about export control regulations.
If you wish to obtain an RTL for use in defence systems, please contact us to discuss this matter before placing your order.
University / college licences
We are happy to for universities and colleges to use our public TTRDs (without charge) in courses for which a degree up to and including “MSc” level (or equivalent) is awarded. No licence is required.
Use of the techniques and code examples described in the ERES books in university research projects (including PhD-level programmes and equivalent) or in commercial training courses delivered by a university or college (for example, professional “short courses” for which no degree is awarded) always requires a licence.
Please contact us for details.
