DDC-I and Rapita Systems Simplify Verification and Certification of Multicore Avionics Applications

Phoenix, AZ. & York, UK.  April 21, 2020.  DDC-I, a leading supplier of software and professional services for mission and safety-critical applications, and Rapita Systems, a leading provider of software verification tools and services, today announced the integration of Rapita’s verification tools (RVS) with DDC-I’s Deos DO-178C DAL A certifiable safety critical RTOS. The integrated platform simplifies multicore verification and certification by providing the safety critical timing information needed to satisfy CAST-32A guidance, enabling developers to simulate multicore resource contention, characterize interference patterns, and provide the certification evidence needed to prove that competition for shared resources does not adversely affect the execution of safety-critical tasks.

DDC-I and Rapita have worked closely to develop a seamless, hardware-agnostic integration of RVS with Deos, portable to every architecture supported by Deos (PowerPC, ARM, and x86). Tracing is accomplished by applying RVS instrumentation with a trace mechanism available within the Deos kernel. Rapita’s RapiDaemons provide a means of generating contention for specific resources that are shared by multiple cores in the system and observing the resulting interference. Together, these capabilities enable developers to understand timing and cross-core interference on Deos-based multicore systems and determine how to best coordinate multicore applications for optimal system performance consistent with the CAST-32A objectives.

“We are excited to be working with Rapita to offer Deos users seamless access to Rapita’s world-class verification tools,” said Greg Rose, vice president of marketing and product management at DDC-I. “Rapita tools running atop Deos provide an ideal platform for characterizing multicore resource contention issues, bounding real-world worst-case execution times, and providing the certification evidence needed to meet CAST-32A objectives.”

“RTOS/tool integration often requires substantial NRE for our customers at the application level,” added Guillem Bernat, CEO at Rapita Systems. “Deos provided the native hooks we needed for a seamless integration that minimizes NRE and provides a best-in-class, out-of-the-box verification, WCET timing analysis and certification solution for our joint avionics customers.”

RapiTask provides scheduling visualization and analysis, helping avionics developers identify and analyze system level resource issues. By displaying CPU utilization metrics at each time point of code execution, and allowing programmers to jump to specific time intervals, RapiTask makes it easy to identify utilization issues and verify that each application meets its requirements. With the addition of RapiTime, which provides on-target timing analysis, programmers can also determine worst-case execution time (WCET) for each task.

RapiDaemons interference generators provide a means of simulating contention for shared resources from applications running on multiple cores and form a key part of Rapita’s end-to-end CAST-32A Compliance package.

Deos is a safety-critical embedded RTOS that employs patented slack scheduling, memory pools and cache partitioning to deliver higher CPU utilization than any other certifiable safety-critical COTS RTOS. First certified to DO-178 DAL A in 1998, Deos provides a FACE Safety Base Profile that features hard real-time response, time and space partitioning, and both ARINC-653 and POSIX interfaces.

Deos SafeMC™ technology extends those advanced capabilities to multiple cores, enabling developers of safety-critical systems to achieve best in class multicore performance without compromising safety-critical task response and guaranteed execution time. SafeMC employs a bound multiprocessing (BMP) extension of the symmetric multiprocessing architecture (SMP), safe scheduling and cache partitioning to minimize cross-core contention and interference patterns. These features enable avionics systems developers to address issues that could impact the safety, performance and integrity of a software airborne system executing on Multi-Core Processors (MCP), as specified by the Certification Authorities Software Team (CAST) in its Position Paper CAST-32A for Multi-core Processors.

DDC-I and Rapita will offer free a joint webinar on this solution for multicore analysis on April 22 at 8:30 PDT, 16:30 BST. Registration information – https://bitly.com/DDCWB2002

Performance Software Partners with DDC-I in Providing Innovative Development Solutions to the Safety-Critical Space

Combination of JETS and Deos Platforms Sets New Standard in Both Safety & Performance

PHOENIX, March 12, 2020  –  Performance Software (PSW), a systems and software engineering firm specializing in embedded avionics and full life-cycle solutions for safety-critical industries, and DDC-I, a leading supplier of software and professional services for mission and safety-critical applications, today announced DDC-I’s Deos DO-178 Multicore Real-Time Operating System (RTOS) is supported by PSW’s JETS, a cloud-based systems and software virtualization platform. Together, the integrated solution enables embedded development teams to quickly and safely scale by reducing dependencies on target hardware.

PSW’s JETS is a cutting-edge avionics digital twin solution enabling safety-critical programs to create, test, and certify with the FAA approved virtual platform. Developers can realize the benefit of unlimited access to hardware, faster time to market, and increased safety with higher-quality software.

“We are excited to have the Performance Software JETS virtualization environment integrated with Deos,” said Greg Rose, Vice President of Marketing and Product Management at DDC-I.  “This collaboration allows our joint customers to reduce dependencies on the availability of target hardware that is one of the primary factors that leads to software and program delays for safety critical avionics programs. ”

Deos from DDC-I is a time and space partitioned, hard real time, safety-critical embedded RTOS that was first certified to DO-178 DAL A in 1998. Today, Deos has been extended with its  SafeMC™ technology that broadens its advanced capabilities to multiple cores, enabling developers of safety-critical systems to achieve best in class multicore performance without compromising safety-critical task response and guaranteed execution time. SafeMC™ employs a bound multiprocessing (BMP) extension of the symmetric multiprocessing architecture (SMP), safe scheduling, and cache partitioning to minimize cross-core contention and interference patterns that affect the performance, safety criticality and certifiability of multicore systems. These features enable avionics systems developers to address issues that could impact the safety, performance and integrity of a software airborne system executing on Multi-Core Processors (MCP), as specified by the Certification Authorities Software Team (CAST) in its Position Paper CAST-32A for Multi-core Processors.

“Avionics products of today are complex and require innovation for speed and efficiency while maintaining the highest level of quality.” said Mike Johnson, Head of Products at Performance Software. “PSW recognizes Deos as a best of breed RTOS and is excited to enable this support for our customers.”

The benefits of a JETS-Deos integrated solution includes:

  • Functional certification utilizing JETS as an off-target formal execution environment
  • Binaries of applications under test can transmit to and from the target without recompiling by leveraging Deos’ binary modularity
  • JETS ‘data bus’ hooks into Deos’ IOI enabling data decoupling and the ability to create data stimuli conditions that may be difficult to produce in real world targets
  • Scalable to complex multi-node control or IMA systems requiring synchronized clocking and data sharing
  • Offered on Arm, PowerPC, and x86

The integration of JETS and Deos offers a highly effective and cost-efficient solution for safety-critical applications. Together the companies take a giant leap forward in breaking new ground and advancing technology to create a safer, more efficient environment for the Safety-Critical space.
