Richardson, TX& – A new model-based test methodology for ASSET® InterTech’s ScanWorks® platform for embedded instruments extends non-intrusive boundary-scan (JTAG) test coverage to devices that previously could not be tested or programmed with boundary scan. ASSET is the leading supplier of tools for embedded instrumentation.
With the new modeling method, referred to as the ScanWorks Component Action, an engineer can quickly describe certain devices like system monitors on the I2C (Inter-Integrated Circuit) or SPI (Serial Peripheral Interface) buses, switches, power managers, LEDs (light emitting diodes), clocks, data converters and memories that do not typically conform to the IEEE 1149.1 boundary-scan (JTAG) standard. When a model has been created in the Component Action, it can be placed in a library so that it can be re-used and automatically included in any number of boundary-scan tests for different circuit boards or platforms. Previously, a great deal of tedious manual effort was required before these devices could be tested or programmed with a boundary-scan test tool.
“The ScanWorks Component Action has a new graphical user interface which simplifies non-boundary-scan device modeling as well as test and bus definition,” said Kent Zetterberg, ASSET’s product manager for ScanWorks boundary-scan test tools. “It’s a very powerful tool that saves test engineers a tremendous amount of time because many of these devices are used over and over again in new designs. Once the model is generated, it can be dropped into any new test that ScanWorks generates.”
Component Action models of non-boundary-scan devices will be added to the constantly growing ScanWorks online model library. The library currently contains tens of thousands of models for boundary-scan devices and other types of non-boundary-scan devices, including memories like NOR/NAND flash, EEPROM, RAM, SRAM, DRAM, DDR SDRAM and others. All of these models significantly shorten the time engineers spend developing tests by enabling automatic test pattern generation (ATPG) within ScanWorks.
