<\/span><\/div><\/div><\/div>Electronic board testing<\/span><\/a>: boundary scan testing combined with functional testing<\/strong><\/h3>\nElectronic board testing<\/span><\/strong><\/a> includes several steps aimed at evaluating the behavior and performance capability of electronic boards. The testing of medium-complex boards at the end of production has historically consisted of ICT testing followed by functional testing. The increasing complexity of digital electronic components, however, has made the Boundary Scan interface increasingly present, which is available on all state-of-the-art digital components such as FPGAs, microcontrollers, RAM, and converters.
\nAs provided by the IEEE 1149.x JTAG standard, Boundary Scan involves circuitry within chips that makes available a complete board-level test protocol. Appropriately implemented by chip vendors, the aforementioned circuitry involves replacing physical probes (probes) with Boundary Scan - BSC cells. They simulate virtual probes for each input and output on the chip and each allows the user to:<\/p>\n\n- observe the usual flow of data through the I\/O pins<\/li>\n
- check the pin status through the serial communication of the Boundary chain.<\/li>\n<\/ul>\n<\/div><\/div><\/div><\/div><\/div>
The Boundary Scan test<\/strong> makes it possible to verify:<\/p>\n\n- the proper interconnection of all components, such as the absence of short circuits between tracks and verification of continuity<\/li>\n
- the presence of many components while not being able to verify their exact value.<\/li>\n<\/ul>\n
However, it cannot completely test all circuits on an electronic board, such as analog parts or all components without a Boundary interface. For this very reason, association with a functional test is indispensable. Indeed, this will allow to complete the testing of the system in all parts uncovered by the Boundary Scan and to perform the actual functional test.<\/p>\n
The integrated Boundary Scan\/Functional Test approach<\/strong> thus allows:<\/p>\n\n- have a dual type of test in a single device<\/li>\n
- improve the test itself, which becomes more reliable<\/li>\n
- have total coverage of all circuits in the Dut and all nets<\/li>\n
- boast shorter test times<\/li>\n
- improve insystem programming performance<\/li>\n
- achieve better and more accurate fault diagnostics with unique reporting.<\/li>\n<\/ul>\n<\/div><\/div><\/div><\/div><\/div>
