Embedded Functional Test

Integration of functional tests such as access to I²C and SPI components

Functional test of modern electronics using the native component intelligence - realized by Embedded Functional Test. The creation and application of test scenarios takes place entirely in a system, which is formed by a common control hardware and a common control software.

Embedded Functional Test allows the integration of functional tests such as access to I²C and SPI components, measurement and evaluation of analog processor inputs, dynamic memory tests and test of high-speed interfaces (e.g. USB 3.0.). Typically these tests are used as an extension to existing structural tests (Boundary Scan, ICT or Flying Probe).

The Embedded Functional Test also detects errors in the dynamic range, which is not possible with purely statistic tests in the normal case. In contrast to the classical function test, no board-specific firmware is required.

A total of four combinable technologies form the pillars of the Embedded Functional Test

The standardized method simply addresses complex components such as FPGAs, processors, controllers and CPLDs. Detailed hardware knowledge is not required.

This method integrates the FPGA logic into the test. Even complex test applications are easy and efficient to solve with ChipVORX. Access to internal Gigabit links and other functionalities (frequency measurement, flash access, RAM tests) is possible via universal FPGA models (no separate adaption necessary).

A processor-specific model allows the processor to enter the debug mode. With VarioTAP individual functions (analog registers, flash access, real-time RAM tests) are addressed. Both the JTAG port and other debug interfaces are supported.

Processor based programming with a universal firmware (JEDOS)

Using JEDOS (optimized for test and programming applications), complex function tests with a graphical user interface are realized. These are complete memory tests, efficient flash access or interfaces tests (Ethernet, USB …). The tests can be created in the shortest possible time without special hardware knowledge.
