SIListra Systems

What SIListra Systems does

SIListra Systems GmbH is a Dresden, Germany-based software company founded in 2012 as a spin-off from TU Dresden, specializing in functional safety solutions for safety-critical embedded systems. The company's core product, SIListra Safety Transformer, is a TÜV SÜD-certified development tool that applies patented "Coded Processing" source-to-source transformation to standard C/C++ code, enabling detection of transient hardware errors at runtime and supporting functional safety compliance up to SIL 3 under IEC 61508 and ASIL D under ISO 26262. Unlike conventional safety architectures that rely on redundant lock-step processors or specialized safety microcontrollers, SIListra's approach runs on standard commercial off-the-shelf (COTS) hardware, materially lowering the bill-of-materials cost of achieving functional safety certification.

The underlying Coded Processing technology is protected by five patents (four German, one US) and is certified across multiple functional safety standards including ISO 26262, IEC 61508, ISO 13849, IEC 62061, and EN 50716 (SIL 4 for railway). SIListra generates revenue through a software licensing model offering Single User, Network, and CI-Build license tiers, supplemented by professional services covering integration, certification support, and custom development. The go-to-market blends direct enterprise sales with a growing partner-led distribution layer.

SIListra serves a diversified base of industrial automation, automotive, railway, aerospace, medical, and agricultural machinery customers. Disclosed end users and integration partners include CODESYS, Continental, Honda Research Institute, SICK, Robert Bosch, and SBB (Swiss Federal Railways). The company has approximately 20+ employees, operates from Dresden, and is privately held.

Core offering

SIListra Systems develops and licenses the SIListra Safety Transformer, a TÜV SÜD-certified source code development tool that automatically instruments C/C++ programs with its proprietary Coded Processing technology to detect runtime errors and achieve functional safety compliance (up to SIL3/ASIL-D) on standard COTS hardware. The company complements the tool with professional services including safety platform consulting, safe fieldbus stack implementation (FSoE, PROFIsafe, OPC UA Safety), toolchain integration and validation, and training workshops.

Product overview

SIListra Systems offers a software-based functional safety solution centered on the SIListra Safety Transformer, a TÜV SÜD certified development tool for C/C++ code instrumentation. The SIListra Safety Transformer implements Coded Processing technology to detect hardware errors in software running on standard (non-safety) hardware, eliminating the need for specialized safety components. The core product is complemented by professional services including Safety Platform design and implementation, Safe Fieldbus protocol stack development (FSoE, PROFIsafe, OPC UA Safety), Integration and Validation services for embedding the tool in customer toolchains, Tool Chain Validation for C/C++, and Training. The company is developing Rust language support through the CoPoRust research project and floating-point arithmetic support through the SafeFloat project.

Scale indicators5 records

Recent moves8 records

Expansion highlights6 records

Regional players

• HIMA Paul Hildebrandt: HIMA is a German-based independent vendor of SIL3/SIL4 safety automation systems for process industries and rail signaling. While primarily a safety controller vendor, it overlaps with SIListra in industrial safety architectures where SIListra's Coded Processing could replace or augment HIMA-style hardware safety PLCs.

Broad incumbents

• STMicroelectronics: STMicroelectronics produces SPC5 and Stellar safety MCUs and provides functional safety documentation packages. It competes for the same ASIL-D and SIL3 design wins and offers an alternative silicon-plus-tools approach to safety-critical embedded systems.
• Renesas Electronics: Renesas offers RH850 and R-Car safety microcontrollers and accompanying functional safety solutions across automotive and industrial automation. It is one of the major hardware incumbents whose safe-MCU roadmaps compete with SIListra's "safety on standard COTS hardware" pitch.
• NXP Semiconductors: NXP supplies S32K3 and other ASIL-D rated automotive MCUs paired with its S32 safety software ecosystem. NXP represents the incumbent silicon-and-software stack SIListra competes against when customers weigh hardware vs. software safety architectures.
• Infineon Technologies (AURIX): Infineon's AURIX family is the dominant SIL3/ASIL-D capable automotive and industrial MCU family, representing the hardware-based safety approach SIListra's software aims to displace. Both companies compete for the same functional safety budget at OEMs, with Infineon leading in hardware lock-step silicon.

Direct peers

• Wind River Systems: Wind River provides VxWorks and safety-certified RTOS/toolchains for aerospace, automotive, industrial, and rail applications. It competes with SIListra in the adjacent software layer for functional safety development environments targeting IEC 61508, ISO 26262, and EN 50128/50129.
• CODESYS: CODESYS is a leading IEC 61131-3 controller platform whose Virtual Safe Control SL product is built directly on the SIListra Safety Transformer. The two firms co-exhibit at trade shows and are deeply coupled: SIListra is both CODESYS' supplier and a direct competitor in the safety-tooling stack for industrial automation customers.
• Green Hills Software: Green Hills' INTEGRITY RTOS and safety-certified development tools serve the same SIL/ASIL-D toolchain market as SIListra, particularly in automotive, industrial, and rail embedded development. Both firms sell TÜV/SGS-certified safety toolchains targeting IEC 61508 and ISO 26262 compliance.
• Scontain: Scontain partners with SIListra (announced March 2024) to combine Scontain's safety/security container technology with SIListra's coded processing. Both target safety-critical embedded software buyers and overlap in industrial and automotive functional safety markets.

Others

• tracetronic GmbH: tracetronic is SIListra's majority shareholder (since 2016) and operates in adjacent automotive software-testing and validation tooling. It is a strategic investor and ecosystem partner rather than a direct product competitor, but it shares automotive customer relationships and the functional safety tooling space.
