Da Vinci Communications is supporting a bid to create the world’s fastest silicon powered solar car of 2007.

The car, called Solar Fern, is the New Zealand entry in the 2007 Panasonic World Solar Challenge, which started today. This race pits solar cars against each other in a gruelling 3000km event across the Australian outback from Darwin to Adelaide. The team intends to drive more than 600km each day, reaching top speeds of 120 km/h.

Kathrin Kiefer, Sales Director for Da Vinci Communications GmbH, says the Solar Fern support reflects Da Vinci Communications’ interest in promoting sustainable energy. The company has a close relationship with New Zealand’s innovative technology industry.

Da Vinci Communications’ support has helped fund the design of Solar Fern using technologically advanced, high performance materials, including a carbon fibre body shell, lithium batteries and composite wheels.
The design features several secret innovations that are expected to challenge traditional ideas about how to harness solar power for transportation purposes. The World Solar Challenge is more than just a race. Over 3000km, reliability and organisation can become key factors.

The intelligent Find Conflicts feature is a response to an urgent request by 3GPP MCC group to Da Vinci’s TTCN experts.
3GPP MCC develops the standardised test specifications for conformance testing of third generation mobile systems and is made up of the world’s leading telecommunications designers and manufacturers.

3GPP’s request came when they tried to merge multiple specifications into one flat test suite. This created an extremely difficult, time-consuming process requiring manual checks for conflicts in these modules. Accuracy would have been extremely difficult to achieve.

“We saw the opportunity to create the feature for use in any type of collaborative test specification development process, where individual developers work on certain parts of a test specification,” says Da Vinci Communications sales manager Kathrin Kiefer. “Da Vinci’s feature enables conflicts to be identified comprehensively and accurately in a matter of minutes.”

Find Conflicts allows developers to investigate identifier conflicts in up to 15 files before integrating various test modules or performing a Merge operation. The conflicts are shown as colour codes in a table and easily viewed at a glance. By clicking on any file cell in the table the corresponding object in its editor window is brought to the foreground for further viewing or editing.

Auto Completion

The updated Leonardo Editor also features a new sophisticated Auto Completion feature. This significantly increases developers’ productivity and accuracy, saving significant time and cost.

Conformance test specifications can easily contain up to 10,000 identifiers. Accuracy is compromised if a developer tries to remember the identifiers, and it is extremely time consuming to manually search for the correct identifier while programming.

Auto Completion enables developers to press “Ctrl + [space bar]” and a list with suitable identifiers pops up. If the developer completes the first few characters, Auto Completion can provide a shortlist of options to select from.

The feature was a response to feedback from developers using Da Vinci’s Leonardo Editor.
Other features in the Leonardo Editor update include:
- numerous improvements in the syntax and semantics checker
- a new plugin API for improved session functionality
- a new preference showing a warning before the developer performs a sort
- a new option to Close Session

The upgraded software thinks ahead of test engineers to help simplify their TTCN-2 development process in this highly complex formal specification language. Features include a dependency checker that identifies where objects are being used and what impact changes to an object will have on the entire specification.

A fast and sophisticated syntax and semantics checker (which includes ASN.1) enables test engineers to verify the correctness of their edited specifications before compiling. The syntax and semantics checker adheres closely to the TTCN-2 and ASN.1 standards, but can also be set to a lower level of compliance.

There are also session features for managing modular TTCN-2, improved handling of multiple windows, and a redesigned user interface.

Da Vinci support manager Kathrin Kiefer says the enhancements are the result of feedback from the company´s large and enthusiastic test engineer community. "Over the last couple of years, we have had excellent feedback from users, and we have been able to incorporate it all into some very innovative features designed to make their lives easier," she says.

Da Vinci Communications´ TTCN-2 editing tools have achieved broad acceptance in international markets. Clients include telecom companies worldwide, equipment manufacturers such as Nokia, Samsung, Motorola and Sony Ericsson, and private network operators and telecommunications research centers.

The Delta Dependencies Plugin combines the powerful comparison functionality of the popular Leonardo Delta tool with Leonardo Editor’s intelligent TTCN-2 dependency checker.

This plugin uses Delta’s comparison reports to find all test cases that are affected by the changes. This means these test cases, once identified, can be easily extracted and re-executed.

The successful launch 3 years ago of their Leonardo range of TTCN-2 browsers and editors to the telecom marketplace, prompted their customers to request that they do the same with TTCN-3. They now include Terzo, for this standard, in their portfolio of tools.

Currently under development for release in 2003 the Terzo tool suite will enable manufacturers to get their products to market faster, and is very suitable in the widening field of IP-based protocols, API testing and 3G - third generation wireless communications.

New markets will open up as TTCN-3 expands the technical possibilities and broadens its appeal for as-yet-uninvolved industries and technologies. It will enable the introduction of a structured, system-oriented approach in areas currently dominated by homegrown and proprietary solutions.

For those clients who have requested some immediate tools, Da Vinci Communications have released the first tabular TTCN-3 browser available on the market. With the Terzo Browser you can browse TTCN-3 test specifications that are written in the core notation, and view them in the tabular representation (TFT), according to the standard - ES 201 873-2 as specified by ETSI. Terzo Browser has been introduced as the first component of the new Terzo tool suite and is freely available for download here. For further details see our Terzo site.

Besides offering new key combinations for quick access, it also offers 3 very convenient functions Find dependencies, Merge and Extract . . . allowing a test suite to be broken down into multiple test suites or modules and merging them back together to one test specification. For those developers who are debugging large test specifications . . . it will be useful to single out test cases as a subset of the test suite to achieve shorter compiler cycles. It supports you in eliminating potential problems through trial and error repetitions, without having to wait a long time for the compiler and semantic checker to finish. Full details are available on the support page.

The plug-in integrates two separate test system components when TTCN is the test notation being used. Da Vinci Communications continues the successful plug-in development to save users cost, time and risk of error.

This synergy solution will be available by August 2001.
