BELIeVE-DV BELIeVE-QA
BELIeVE-QA is for use in product manufacturing scenarios, or as part of a CI toolchain, and runs on the PC’s command line. It is supplied with a Getting Started guide and a node-locked licence for a single PC for one-year and costs just £950+ GB VAT.
During product development, BELIeVE can be used to inject faults and mimic events/conditions that would otherwise be hard to replicate. Wrigely explains: “What specifically interests me and Bermondsey Electronics is faults because faults are typically difficult to reproduce in tests. Faults can lead to all sorts of weird and wacky behaviour and they are, generally speaking, a pain to debug. With this product we get a high level of confidence the product is working as expected and that the interface and its environment, which is the tricky bit to test, is functioning the way we intend it to work.” BELIeVE is effectively a new kind of embedded system development tool, one that builds on the well-proven test-driven development (TDD) methodology, with which software engineers will be familiar. BELIeVE not only brings the product’s real hardware into the equation but also allows the creation of a simulated environment in which the DUT can operate. Once networked with instrumentation - such as benchtop power supplies, oscilloscopes, dataloggers, DMMs - BELIeVE runs scripts that can, for example, change input power, drive analogue and digital inputs, and record outputs. It is also possible to simulate user interactions, such as keypad button pushes and switch throws, meaning test can run unattended. In addition, as Wrigley highlighted,

BELIeVE-DV is ideal for design and verification work and is supplied with editable interface libraries so that engineers can write their own tests. Enabled user interfaces include Test Manager, Project Manager, Test Editor and Command Line Interface. An unrestricted period BELIeVE-DV node-locked licence for a single PC costs £8,495+ GB VAT. Alternatively, for a node- locked licence for a single PC for one year, the cost is £4,995+ GB VAT. BELIeVE is supplied with a Getting Started guide, sample interfaces (including BLE and ANT+ serial ports), a comprehensive list of Test Editor commands and comes with up to 10 hours of free support from Bermondsey’s technical specialists.
BELIeVE enables multiple engineers to work with expensive test equipment remotely – something that is important in this pandemic age as it allows tests to be carried out even when engineers are working from home. Being JavaScript-based also answers another challenge facing industry at the moment – recruitment. By using JavaScript, it increases accessibility as it does not require engineers to have an in-depth knowledge of C# or Python. Fully functional evaluation versions of BELIeVE-DV and -QA can be downloaded from Bermondsey Electronics’ website,
www.bermondseyelectronics.com, and will function for 30 days before requiring a licence. The company also plans to launch a Youtube channel that will provide support videos for users. “Like all good inventions, BELIeVE was born of necessity,” concludes Wrigley. “We needed a highly capable integration verification engine to support our own design and test services. When we presented the verification engine at UKEmbedded in May this year, the audience reaction was staggering. In just a little over four months we have commercialised a powerful embedded systems verification tool we feel has the potential of transforming the industry.”

THE BENEFITS OF BELIeVE INCLUDE:
Tests can be performed far quicker than is possible manually, saving you a great deal of time.
Comprehensive test coverage – explore all permutations of input conditions with the finest of granularity/resolution to unearth corner cases.
Highly repeatable tests. Batch testing is possible.
No risk of human error (missing a measurement or misinterpreting a reading).
Inject faults to satisfy yourself that your product handles errors correctly. Reports are automatically generated.
Equipment independent (as long as it has a comms port, we can talk to it).
No tie-in, which is not the case with software available from other T&M equipment vendors (they want your long-term business).
