Validation Suites and Kits for
Weston Embedded Solutions' Cesium RTOS

Certification Evidence for use in Avionics, Medical, Industrial Control and Transportation

Validated Software Corporation (VSC) released the first Validation Suite for Micriµm’s µC/OS real-time operating system (RTOS) in 1999. Silicon Labs who acquired Micrium in 2015 recently announced that it no longer commercially licenses the Micrium µC/OS products. Weston Embedded Solutions now offers the Cesium RTOS, a commercially licensed RTOS that is derived from Micrium's µC/OS products and completely free from modification by open source contributors. VSC is proud to provide its Validation Suites and Kits for the Cesium product line as a natural evolution of its equivalents to the Micrium products.

Validation Suites contain all software development life-cycle documents, test results and essential evidence demonstrating that the Cs/OS2 kernel embedded in your hardware meets the strict standards set forth by international safety-critical standards.

With its tiny footprint and efficient operation, the scale-able kernel consumes few resources yet provides a powerful set of services that reduce risk, tame complexity, and accelerate software schedules. When Cs/OS2 is used in critical avionics applications, Validation Suites offer a similar set of benefits to those concerned with ensuring that the software system was developed and maintained in accordance with standards.
Incorporating the best features offered by their “off-the-shelf” nature. Ninety percent of the Cs/OS2 Validation Suite is “pre-existing” and has been used for “previously certified” software. Like the Cs/OS2 real-time operating system, Validation Suites have a proven record of accomplishment across a wide variety of microprocessors, digital signal processors and toolsets.
They also offer many of the benefits of a custom solution. Validation Suites use run for credit results from your choice of hardware target and the tools you select for the project. Validation Suites use robust unit-testing, integration testing and code coverage testing techniques that allow you to use all Cs/OS2 APIs and Services across a wide range of configurations without the need for retest.
Validation Suites, as well as the rest of VSC’s products and services focus on supporting the way you and your team work.  They provide more than a set of certification documents, test results and software. Validation Suites provide you with options and flexibility. You choose the processor, AND compiler, AND development tools AND assurance level, AND delivery date. Then VSC does the rest. In sixty days or less and at a fraction of the cost of comparable in-house and commercial alternatives, VSC will deliver your Cs/OS2 Validation Suites for virtually any 32 and 64-bit microprocessor, DSP, or soft-core processor.
