Corelis CVXI-1149.1 Boundary Scan Controller Board

The Corelis CVXI-1149.1 is a VXIbus-based boundary scan controller board for IEEE 1149.1 (JTAG) testing and in-system programming of electronic circuits. It has a solid interface between the VXIbus and JTAG-compatible targets, enabling comprehensive testing, debugging, and programming without direct physical probing. ## Technical Specifications • IEEE Standard 1149.1 (JTAG) compliant • Six independent serial scan test busses • 64 bits of parallel I/O • Programmable scan test clock rates • VXIbus module form factor • Four-signal cable interface per TAP ## Key Features • Automated testing of PCB interconnects and functional validation • Built-In-Self-Test (BIST) command execution on target circuitry • In-system programming (ISP) of devices within circuit designs • Fault isolation through access to internal device functions not reachable by external probing • Precise signal generation under software control • Multiple independent scan buses for parallel test operations ## Typical Applications • Production board testing and manufacturing quality verification • In-circuit device programming and re-programming • Internal fault diagnostics within integrated circuits • Debug and validation of circuit board designs prior to deployment ## Compatibility & Integration The controller integrates directly into VXI chassis via the VXIbus interface. It connects to JTAG-compliant target systems through standard four-signal cables. Operation is controlled through Corelis ScanExpress™ software family. Compatible with any JTAG-compliant target device or system.
