JTAG Boundary-Scan I/O Modules
The Corelis family of SCANIO™
modules turn any IEEE standard 1149.1 boundary-scan controller into a
powerful digital boundary-scan tester. The SCANIO family of products use
boundary-scan gate arrays to add control and visibility to connectors,
traces, and logic that can not be tested using traditional boundary-scan
The SCANIO products, when combined with a boundary-scan controller, operate
as a traditional "bed-of-nails" tester except access to the stimulus and
response I/O's is achieved via boundary-scan.

The ScanIO-300LV digital I/O
module turns an IEEE-1149.1 boundary-scan controller (such as the
Corelis PCI-1149.1/Turbo™ or NetUSB-1149.1™) into a powerful digital
interconnect and functional tester. It uses boundary-scan compatible
ASICs to add control and visibility to connectors, traces, and logic
that can not be tested using traditional scan techniques. The
ScanIO-300LV, combined with a boundary-scan controller, operates as a
traditional “bed of nails” test system except access to the stimulus-and
response I/Os is achieved via boundary-scan, and the size and the cost
of the system are significantly smaller than traditional testers.
The ScanIO-300LV module
provides a total of 300 fully bidirectional test channels with virtually
unlimited memory depth per pin. Each line is independently controlled
and can be individually configured as an input or output. During
testing, the programming and control of the test channels is
automatically performed by the ScanExpress™ tools without any user
intervention. The voltage level of the I/O and JTAG interfaces is
programmable from 1.25V to 3.3V and supports either single ended or low
voltage differential (LVDS) signaling.
modules can be cascaded in series providing a sufficient number of pins
for almost any digital test environment. By using single or multiple
ScanIO-300LV modules, existing Automatic Test Pattern Generators (ATPGs)
can be used to test non-scannable elements such as connectors, cables,
and devices not incorporating boundary-scan. The ScanIO-300LV connects
to the UUT inputs and outputs with standard flat-cables that can
optionally be terminated with test probes.

The ScanPCI boundary-scan based PCI and Compact PCI Card Tester provides
a convenient method to test PCI and Compact PCI boards and their
card-edge connectors. The ScanPCI adds boundary-scan control and
visibility to PCI and Compact PCI connectors that would otherwise be
untestable or require expensive wiring adapter harnesses.
Even for those PCI and Compact PCI cards that have been designed with
boundary-scan testing in mind, the circuitry between the PCI or Compact
PCI card edge itself and the PCI interface devices, which typically have
JTAG capability, is usually not fully boundary-scan testable. The
Corelis ScanPCI™ provides a way to quickly and easily access these hard
to reach connections and increase the boundary-scan test coverage of the
Unit Under Test (UUT).
ScanPCI interfaces with a UUT that is either a 3.3V, 5V, or a Universal
voltage device. Refer to the detailed datasheet of the ScanPCI for

The ScanDIMM™ Digital Tester
modules are an easy to use tool for interconnect testing of memory DIMM
Through the use of boundary-scan technology, the ScanDIMM Tester
provides fully bi-directional test signals. A boundary-scan Test Access
Port (TAP) connects to a host computer which provides virtually
unlimited memory depth for testing each of the DIMM socket(s) pins.
DIMM sockets are often used for Double Data Rate (DDR) Synchronous
Dynamic Random Access Memory (SDRAM) and other types of memories and the
ScanDIMM offers an accurate and easy to use mechanical and electrical
solution for testing connections to the DIMM socket(s).
Support is available for a number of DDR, DDR2 and DDR3 modules
including 184-pin DIMM, 168-pin DIMM, 144-pin SODIMM, 200-pin SODIMM,
204-pin DIMM, and 240-pin DIMM.
