Signum Systems™ designed and developed software and hardware development tools for the embedded market worldwide since 1979.

Early on, we found ourselves squarely in the mainstream of the full-featured in-circuit emulator (ICE) market, serving majority of hard disk drive manufacturers and 8-bit and 16-bit MCU makers.

In mid 1990’s Signum Systems switched to support the growing DSP and ARM markets with the JTAGjet line od debug probes which used the JTAG bus connection for debugging, rather than the entire address/data bus.

In 2011, Signum Systems was acquired by IAR Systems AB, where we continued to design newer and more versatile debug probes for the ARM/Cortex™ family of devices

This web site is now dedicated to provide our customers with continued sales and support for some of the legacy products we introduced before the acquisition.
