JTAG/Boundary Scan integration in In-Circuit-Test (ICT) systems
In-Circuit-Test (ICT) is the most widespread technology at present because the principle allows all electrically detectable faults to be found. But its capability is becoming limited by access difficulties since components have become smaller, and because of more complex narrow width nets and multi-layer boards.
Boundary Scan does not have access limitations. A combination is beneficial whenever mechanical access is difficult even though there may be a small number of Boundary Scan components on the PCB.
Advantages:
- Very fast total system
- Very high fault coverage also for highly compact PCBs
- Reduction of nail bed adapter costs
- Simple test program generation because each test technology is applied according to its core competence

Combination of PTI Tester PTI818Swith SCANFLEX Hardware:
- Controller SFX/PCI1149
- SFX-TAP4 for Pin Slot
and Software:
- CASCON GALAXY for PTI818S
PTI818S - Utility Card Module CASCON GALAXY
Die PTI818S is eine professionelle JTAG/Boundary-Scan-Option, welche speziell für die Utility Card von Agilent entwickelt wurde. Der auf der SCANBOOSTER?-Architektur basierende TAP-Controller hat zwei unabh?ngig voneinander programmierbare TAPs, zwei B?nke mit jeweils 4 PIPs und eine Selbsttestfunktionalit?t. Zwei PIP-Signale k?nnen als analoge Kan?le zum Treiben und Messen analoger Werte w?hrend der Testerstellung mit SYSTEM CASCON? benutzt werden.
