During product development, BELIeVE can be used to inject faults and mimic events/conditions that would otherwise be hard to replicate. In addition, reports are automatically generated, which is of great benefit to engineers that must demonstrate their designs were thoroughly verified; for safety-critical applications, for example, but also good engineering practice.
Wrigley goes on to say that 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, data loggers, and 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 the test can run unattended.
BELIeVE is available in two versions:
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), and a comprehensive list of Test Editor commands and comes with up to 10 hours of free support from Bermondsey’s technical specialists.
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 costs just £950 + GB VAT.
Fully functional evaluation versions of BELIeVE-DV and -QA can be downloaded from Bermondsey Electronics’ website and will function for 30 days before requiring a licence.
