Corelis offers a wide selection of hardware interfaces to the PC. Bus architectures such as PCI Express, PCI, PXI/cPCI, USB 2.0, and Ethernet are all supported. The wide variety of hardware controllers provide multiple Test Access Ports (TAPs), user selectable voltages, and test clock (TCK) rates up to 100 MHz.

Corelis additionally offers controllers for concurrent board testing and In-System Programming solutions targeting users looking for high-throughput boundary-scan applications including high-volume production. Four, Eight, and Thirty-two TAP control modules provide the necessary hardware connections to the test units.

Corelis offers I/O modules that allow users to add JTAG control and visibility to connectors, test points, traces, and other logic that otherwise cannot be tested using boundary-scan. These modules provide additional boundary-scan pins which connect with external board interfaces such as PCI edge connectors and DIMM sockets to increase boundary-scan test coverage.
