onTAP

onTAP circuit trace tests allow you to quickly and easily measure boundary scan pins on your PC. Circuit trace adds a rich, natural language scripting tool that enables algorithmic flexibility.

Once a board developer passes along the new board and all related files and procedures to a test developer, the boundary scan test process can begin. We recommend including the TAP Integrity Test at the beginning of your interconnect test because the TAP contains pins associated with the test access controller, e g., the TAP […]

Chip manufacturers are now producing multichip modules (MCMs) that may include two or more arrays of devices within a single package. These modules can be tested using JTAG test pattern generation of the devices while on a PCB. To incorporate JTAG testing of MCMs there are several things that are needed: a netlist of the […]

It’s the return of the Gadget Smackdown, brought to you by EE Live!  This year, the SMACKDOWN takes place April 1–3 in the EE Times Fantastical Theater of Engineering Innovation at the San Jose convention Center, where the EE Live! Conference and Expo is being held. The presser for this event encourages anyone who loves […]

Use this function to: Check the fault coverage of your test for a specific fault condition. Insert an open fault without modifying your board or test fixture. Validate that your test is working as expected. How to Insert Faults 1. Create a file FaultInsert.txt in your test project directory. 2. Add fault declarations to the […]

When large numbers of outputs switch simultaneously, they can cause intermittency with your test due the ground bounce effect. onTAP lets you control this problem by giving you control over how many outputs switch during a single test scan, as shown below:

What Does onTAP Test?   As boundary scan technology grows in popularity, more JTAG compliant devices (1149.1 and 1149.6) are now being included in board design, along with more JTAG chains that often require simultaneous testing. The great advantage to using onTAP, is that there are no restrictions on the number of devices in a […]

  Our Development team has been busy at work on a new UI for onTAP. We’re all excited about the new look and we’re sure you will like it as much as we do. We expect to introduce our new and improved onTAP mid-to-late Q1 2013, so stay tuned for updates. In the meantime, all […]

Many newcomers to JTAG test start their first projects knowing only that boundary scan testing is a requirement for new board design. The specifics of boundary scan, details of test strategy, or expected results are, for many, uncharted territory. In fact, most newcomers to boundary scan testing are uncertain as to what questions to ask […]
