VAPS QCG FAQ
When was VAPS QCG first launched?
VAPS QCG was launched in 2000 with international customer involvement, including Eurocopter, Barco, Smiths, and Elbit.
How does the VAPS/DOORS integration save time in verification?
The VAPS/DOORS interface enhances the user’s control of deliverables by providing a link between the original system requirements and the implementation. The interface provides the capability to assign a DOORS requirement ID to VAPS objects, making it simpler to track changes for hundreds, or even thousands, of objects. The requirements and objects are reusable from project to project, thereby further reducing time and cost.
Which is the proper term used to describe VAPS QCG – qualifiable or qualified?
VAPS QCG has been developed to conform to DO-178B as a development tool and is thus qualifiable. As per DO-178B, tools can only be qualified on a given project. VAPS QCG has been qualified on a number of projects using the Certification Kit ‘off-the-shelf’.
How many programs has VAPS QCG been qualified on?
Today there are more than 15 programs using VAPS QCG, with more being added every month. Ask your sales representative for a complete list.
Does Presagis plan to continue supporting VAPS QCG for years to come?
Absolutely. DO-178B certification is becoming increasingly important to customers, and Engenuity will support VAPS QCG for as long as necessary in order to support its growing user base.
How does DesignDoc automatically generate documentation for verification?
VAPS DesignDoc uses a proprietary technology to output Microsoft Word documents detailing all aspects of a VAPS-built HMI by querying the design files for all the required details. Because DesignDoc is qualifiable as a verification tool, it can be used to review the VAPS design files and low level requirements (LLR) against high level requirements (HLR). When using Telelogic DOORS, the VAPS integration with DOORS allows the user to link DOORS requirement IDs to VAPS objects. This allows the user to maintain traceability for the VAPS application within DOORS. As the DOORS requirement IDs are saved in VAPS as well, they are included in documents generated by DesignDoc, thus facilitating review.
Do I have access to the full set of certification artifacts for VAPS QCG?
The full set of artifacts is available, providing the VAPS QCG Certification Kit was purchased.
How much time and cost can I realistically expect to achieve using this product?
Time and cost savings are tightly linked to several factors, including the number of engineers working on the project, user experience, and the complexity of the actual application being built. Specific users have indicated that 70-80% time savings across the entire project is not an unrealistic metric. It is advisable to speak with your sales representative in order to help you work through a sample project in order to get an accurate estimate for your specific deliverable.
I am concerned about performance. Are there metrics available for final systems developed using VAPS QCG?
Performance will be dictated largely by the target platform and the complexity of the application; however, users can expect excellent performance for most mainstream avionics applications using VAPS QCG. VAPS QCG has met or exceeded embedded refresh targets for some of the most demanding customer applications. Speak with your sales representative for specific platform/application metrics examples.
I have a proprietary target platform requirement for my embedded system. Can I still use VAPS QCG?
Yes. The porting layer allows VAPS applications to be ported successfully to any embedded target, even proprietary ones.
Are Engenuity’s VAPS QCG engineers available in order to help me through my certification project if necessary?
Yes. The product architect and the VAPS QCG engineering team are available and have helped many customers with certifications in the past.
