ITC: Intellitech offers JTAG test platform for PCBs with ARM processors
-- Test & Measurement World, 10/29/2007 10:33:00 AM
Intellitech has announced its new PT100 Pro test platform for testing PCBs with processors based on ARM architectures. The PT100 Pro enables customers to reduce test costs and increase fault coverage by combining mixed-signal test, concurrent IEEE 1149.1 (JTAG) test, and CPU emulation-based functional tests in a single platform for testing up to 32 PCBs at a time. Intellitech CEO CJ Clark reported that customer-specific versions of the tester are already in full production use in Southeast Asia. The company had a system on hand at its International Test Conference booth and presented a video demo of the system in use in one Asian contract-manufacturing facility.
The PT100 Pro is based on Intellitech's award winningPT100 and its patented CJTAG (concurrent JTAG) technology, which enables massive concurrent JTAG-based test and emulation. The concurrent ARM-based emulation test support enables the tester to go beyond boundary-scan stuck-at-faults to include at-speed cluster testing of all of the PCB components, including non-1149.1 devices on a single tester platform. Power, mixed-signal and analog testing are achieved through the PT100 Pro's built-in PXI instruments, power supplies and relays.

"The ARM family accounts for approximately 75% of all the embedded 32-bit CPUs, so it was a natural choice for us to target ARM for this tester's CPU-based functional test support," said Clark. "This tester fills the gap where in-circuit testers can't perform at-speed functional test through the CPU emulation port and frequently are limited as to how many PCBs can be tested at once due to JTAG test pattern depth."
The PT100 Pro supports up to 32 1149.1 controller ports and up to 1870 analog/digital test pins with a pneumatic or vacuum based fixture interface. It includes a PXI chassis and measurement block, dual programmable power supplies, integrated dual-core Pentium-based computer with RAID drive, touch screen monitor, lockable keyboard, bar-code scanner, and Intellitech's ScanExecutive production test software. Prices range from $45,000 to $80,000, depending on configuration.
