Corelis offers bus analysis, embedded test solutions, and the industry’s broadest line of JTAG Boundary-Scan software and hardware products that combine exceptional ease of use with advanced technical innovation and unmatched customer service. Soon after its inception in 1991, Corelis’ innovation in bus analysis and JTAG boundary-scan test solutions ultimately resulted in the company’s acceptance as a major and preferred vendor of test solutions worldwide.


JTAG/boundary-scan technology, standardized under IEEE-1149.1 and updated and expanded by a suite of related standards, has become the method of choice for testing and designing reliable, high-technology, electronic products. Design-for-testability (DFT) practices have enabled new, innovative JTAG applications from debug and test to in-system programming, the technology continues to improve and expand into new areas.

Corelis is a pioneer in the rapid development of innovative IEEE-1149.x-compliant products and services in support of the JTAG Boundary-Scan market. As a result of our ingenuity and contributions to the industry, a growing number of customers have been able to incorporate boundary-scan technology into their product development processes to gain a competitive edge in today’s marketplace.

Corelis Products

Today, Corelis products can be found globally in every industry developing and/or manufacturing electronic products. Corelis’ ScanExpress software applications are used for structural testing as well as JTAG functional emulation test and in-system programming of Flash memories, CPLDs, and FPGAs. Systems include a complete range of IEEE-1149.1-compatible boundary-scan testers for PCI, PCI Express, LAN, USB 2.0, cPCI/PXI, and more host interfaces.

Our business is segmented into two distinct areas:

  • Products: ScanExpress Embedded Hardware Test, Programming, & Hardware Solutions

  • Custom Embedded Hardware Development & Test Systems and System Integration Services

Corelis has developed a complete product family of hardware and software products for JTAG boundary-scan testing and in-system programming. Our ScanExpress software suite is generally recognized as the highest-performance and easiest-to-use PC-based boundary-scan test system available on the market today.

Corelis provides customers with a full range of tools including Test Pattern Generation, Test Execution, complete pin-level diagnostics, CPLDs, FPGAs, and Flash in-system programming. All of this is accomplished from a common Microsoft Windows 7, Windows 8/8.1 and Windows 10-based user interface. Hardware for running the boundary-scan tests includes PCI, PCI Express, USB 2.0, Ethernet/LAN, PXI/cPCI, and VXI modules.

Corelis Services

Corelis also provides various engineering services and is well known for its outstanding customer support. Corelis has thousands of customers worldwide. In addition to its National USA representatives, Corelis has very technically competent sales and support engineers overseas in countries such as Japan, Canada, Sweden, France, Israel, Germany, Korea, Ireland, Singapore, China, Taiwan, UK, Holland, Belgium, Australia, and other countries.

Corelis will provide a customer with a complete turnkey approach to boundary-scan testing. We will work with a customer during the design process to ensure that the design is capable of being tested to the customer’s requirements. When required, we will even create boundary-scan BSDL files for custom ASICs used on the board. We will then create all test vectors, verify them using the customer’s actual hardware, and provide the completed, verified, test system to the customer. In some cases, this will also include a custom test fixture.

Although Corelis’ standard products are the main focus of the company, Corelis also develops custom test and simulation projects with a very high complexity of software and hardware; this allows us to stay on top of today’s technology and support our customers who are using state-of-the-art technology.

Corelis Customers

Corelis’ development and test tools are used by companies such as Dell, Ericsson, IBM, Intel, Jabil, Keysight, Microsoft, Rockwell, Hewlett-Packard, Motorola, Qualcomm, Nokia, Panasonic, Texas Instruments, Ford, Plexus, Broadcom, Ericsson, Flextronics, and many others. Corelis also has ongoing strategic third-party relationships with major industry leaders such as Texas Instruments, NXP, Broadcom, Teradyne, and more.
