Beyond the Boundary Scan Test: Testing for Mid-State/Resistive Shorts

Beyond the Boundary Scan Test: Testing for Mid-State/Resistive Shorts

Mid-state shorts are a major problem that often goes undetected by typical boundary scan connectivity tests is mid-state/resitive shorts. Flynn Systems recognized this “hole” in boundary scan testing and was the first boundary scan test company to test for mid-state shorts, improving test fault coverage.

Using onTAP to test a board

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...

onTAP Supports IEEE 1149.6!

As we have promised our users, Flynn Systems continues to develop and add new features to onTAP Boundary Scan Software.  These new features vastly improve onTAP's capability, enabling onTAP users to do more with less.  We had been developing support for IEEE 1149.6...

onTAP BIST (Built In Self Test)

Tests may be defined in script files which may then be translated into executable Serial Vector Format (SVF) files. The general approach is to place all of the required BSDL files into a folder and then to relate the BSDL files to circuit locations in declarations at...

PC Based Parallel Test

Ontap_parallel.exe can be used to simultaneously run test suites on multiple PC boards using the onTAP DLL. Parallel board testing must be enabled for the DLL license. Testing is fastest on a multiple processor PC , particularly where one core processor is available for each board. For example if four PC boards are being tested in parallel, then a quad core processor is recommended so that the time to test four boards is about the same as that required to test one board.
