JTAG Boundary-Scan Controllers

Corelis JTAG boundary-scan controllers cover every major host bus. USB 2.0, PCI, PCI Express, PXI/cPCI, Ethernet, VME, and VXI are all supported. Most controllers sustain TCK frequencies up to 80 MHz. Engineers gain flexibility to match price and performance to each application. Software stays fully transportable across every hardware platform.

The full line includes the USB-1149.1/CFM, USB-1149.1/1E, USB-1149.1/4E, NetUSB-1149.1/E, NetUSB-1149.1/SE, PCI-1149.1/Turbo, PCIe-1149.1, QuadTap CFM, and CPXI-1149.1/Turbo controllers.

JTAG Controllers for High-Volume Production

Hardware-Based Parallel Operations

Corelis built dedicated hardware for production lines. It performs gang testing and programming of many units in parallel. No operator intervention required. The hardware runs every step and verifies results on the fly. The full pipeline is modular and expandable.

The flagship product is the ScanTAP-32. It pairs with controllers like the PCI-1149.1/Turbo. Together they drive up to 32 simultaneous test access ports.

JTAG Boundary-Scan I/O Modules

What SCANIO Modules Do

The Corelis SCANIO™ family extends any IEEE-1149.1 controller. It turns the controller into a full digital tester. SCANIO modules use boundary-scan gate arrays. These arrays reach connectors, traces, and logic that standard boundary-scan misses.

Pair a SCANIO module with any Corelis JTAG controller. The pair then behaves like a classic bed-of-nails tester. The key difference: signals flow through the boundary-scan chain — not through physical probes.

ScanIO-300LV — Digital I/O Module

Overview

The ScanIO-300LV upgrades a Corelis JTAG controller into a digital interconnect and functional tester. It works with the PCI-1149.1/Turbo™, the NetUSB-1149.1™, and most other Corelis controllers. The module uses boundary-scan ASICs. These ASICs reach connectors, traces, and logic that standard scan cannot test.

Pair the ScanIO-300LV with any controller. The result behaves like a traditional bed-of-nails tester. Signals reach the board through boundary-scan, not probes. The footprint and the cost stay far below a classic ICT system.

Key Specifications

• 300 fully bidirectional test channels, virtually unlimited memory depth per pin
• Per-pin direction control — set each channel as input or output independently
• ScanExpress™ tools drive the channels automatically — no manual intervention
• Programmable voltage from 1.25 V to 3.3 V on I/O and JTAG interfaces
• Single-ended or LVDS signaling supported
• Cascade multiple modules in series for almost any digital test environment

Reusing Existing ATPGs

One or more ScanIO-300LV modules unlock new use cases for your existing ATPGs. The pair can test non-scannable elements. That includes connectors, cables, and devices without boundary-scan. The ScanIO-300LV connects to the UUT through standard flat cables. Test probes can terminate the cables as an option.

ScanDIMM — DIMM Socket Interconnect Tester

Overview

The ScanDIMM™ Digital Tester simplifies interconnect testing for memory DIMM sockets. It uses boundary-scan technology. That gives engineers fully bidirectional test signals on every pin.

A boundary-scan Test Access Port (TAP) connects the ScanDIMM to the host computer. The host then supplies virtually unlimited memory depth for testing each DIMM pin.

Why It Matters

DIMM sockets host DDR SDRAM and many other memory types. Connection problems at the socket cause silent data corruption. ScanDIMM offers a clean mechanical and electrical solution. It verifies every connection to the socket before the memory module ever installs.

Supported DIMM Formats

• 168-pin DIMM — SDRAM
• 184-pin DIMM — DDR
• 200-pin SODIMM — DDR2
• 204-pin DIMM — DDR3 SODIMM
• 240-pin DIMM — DDR2 / DDR3
