PLANO, TX, Sep 23, 2025 – Siemens Digital Industries Software has introduced Tessent IJTAG Pro, a tool designed to accelerate semiconductor testing by enhancing IEEE 1687 input/output. The software enables parallel execution of serial operations and supports read and write access to custom hardware. It also adds internal JTAG (IJTAG) and data streaming functions that work with Siemens’ Tessent Streaming Scan Network (SSN) to reduce testing time and lower costs.
“In today’s complex IC designs, test time optimization is a significant challenge. By utilizing Siemens’ SSN architecture to convert traditional serial IJTAG operations into high-bandwidth parallel processes, Tessent IJTAG Pro not only accelerates test and reduces cost associated with test but also provides flexibility needed for revolutionizing test access to meet the industry’s evolving needs,” said Ankur Gupta, senior vice president and general manager, DDCP, Siemens Digital Industries Software. “As semiconductor design is scaling from simple 2D into full 3D IC architectures, test cost savings will be applicable in each chiplet as well as the entire 3D IC package.”
“High-Bandwidth IJTAG innovatively leverages the SSN bus architecture, and delivers patterns much faster than traditional serial methods, leading to substantial reduction in test application time, especially for BIST & Mixed Signal IP testing,” said Srinivas Vooka, senior engineering manager, Google.
The combination of the features in IJTAG Pro along with the announcement of Siemens’ Tessent AnalogTest software marks an expansion of capabilities and bandwidth.
