DDC-I and LDRA Announce Integrated Tooling for DO-178C Testing for Deos RTOS Users

Deos/LDRA tool suite integration leverages unique RTOS instrumentation hooks to deliver enhanced timing analysis and Worst-Case Execution Time (WCET) test capability, applicable for high design assurance systems and especially useful for multi-core system development

 

PHOENIX, AZ, USA and WIRRAL, UK – June 17, 2024 – DDC-I, a leading supplier of software and professional services for mission- and safety-critical applications, and LDRA, the leading provider of automated code analysis and software testing tools and professional services for mission- and safety-critical applications, today announced an enhanced integration between the Deos safety-critical DO-178C certifiable RTOS and the LDRA tool suite. The integrated solution, qualified to Design Assurance Level A (DAL A), utilizes unique OS-level instrumentation hooks that enable the LDRA tool suite to deliver enhanced unit test and worst-case timing analysis capabilities out of the box.

Unlike conventional RTOS/unit test integrations, which utilize chip-level facilities such as special registers or timers, Deos provides process log events with high-resolution time stamps that link what’s going on at the process level with the kernel’s more uniform/consistent view of time. These OS-level hooks provide for WCET measurement at both the system and task level using the developer’s interference generation tool of choice.

“DDC-I has been at the forefront of DO-178C safety-critical multi-core technology development, standardization and verification, with an emphasis on the guidance of CAST-32A initially, and then more recently the January 2024 release of AC 20-193 Use of Multi-Core Processors,” said Greg Rose, vice president of marketing at DDC-I. “The integration of Deos with the LDRA tool suite gives avionics developers the unit test platform they need to identify and resolve complex multi-core timing issues, especially the worst-case execution scenarios critical to avionics.”

“Proving that an avionics system is properly partitioned to avoid interference from competing cores is critical, yet nearly impossible without the proper development and testing tools,” said Ian Hennell, Operations Director at LDRA. “Deos provides OS-level hooks that give the LDRA tool suite unique visibility into RTOS operation, enabling it to deliver uniform timing analysis with enhanced worst-case execution capabilities, essential for airworthiness certification.”

About the LDRA tool suite

The LDRA tool suite is LDRA’s flagship platform that delivers open and extensible solutions for building quality into software from requirements through to deployment. The tool suite provides a continuum of capabilities including requirements traceability, test management, coding standards compliance, code quality review, code coverage analysis, data-flow and control-flow analysis, unit/integration/target testing, and certification and regulatory support. The LDRA tool suite’s unit and integration testing capabilities provide an intuitive user interface that allows the same tests to be executed in the host or target environments. Where code re-use is in consideration, they allow those same tests to be re-run automatically in different target environments. Test generation (test harness, test vectors, code stubs) and result-capture support is available for a wide range of host and target platforms. Optimized instrumentation technology supports even highly constrained 8- and 16-bit microcontrollers, and through to high-performance 32- and 64-bit processors.

TBwcet is an optional module for the LDRA tool suite that automates the measurement of WCET on the target – the only way to provide evidence of adequate resourcing and mitigation for interference where multi-core processors (MCP) are deployed. Test results and reports generated using TBwcet can be uploaded to LDRAvault. LDRAvault is a web application that automatically aggregates certification artifacts across distributed users and complex projects​, can easily adapt to comply with a growing and evolving certification and regulatory landscape​, supports traditional as well as CI/CD workflows, automatically generates advanced visualizations to gain insights across large and targeted sets of certification data through a ‘single pane of glass’​, and enables effective collaboration across the enterprise and supply chain, and with regulatory authorities​​.

NAI’s Configurable Open Systems Architecture™ (COSA®) utilizes highly modular, portable components that can be added or removed, and reapplied to other system configurations with maximum reuse of DAL-A artifacts. This shared commitment to modularity, portability and reuse enables avionics designers utilizing Deos and the COSA architecture to reconfigure their I/O systems with minimal impact on hardware, software and DO-178 recertification.

“Our SafeMC multi-core technology and reusable verification evidence make Deos an ideal environment for developing, certifying and deploying high-performance, FACE® Conformant, safety-critical avionics applications targeting the 68PPC2 and COSA architecture,” said Greg Rose, Vice President of Marketing at DDC-I. “Our SafeMC technology provides unique solutions to address the AC 20-193 multi-core objectives, delivering best-in-class performance and determinism for safety-critical applications running on NXP PowerPC multi-core processors.”

“Deos running atop the 68PPC2 gives avionics developers an integrated platform that combines high-performance multi-core performance with a best-in-class safety-critical RTOS,” added Lino Massafra, Vice President of Sales and Marketing at NAI. “Developers requiring the highest level of design assurance now have a rugged, flexible, off-the-shelf solution with configurable I/O and DAL-A evidence in a compact, low-power package that accelerates deployment of safety-critical systems.”

Deos is a safety-critical embedded RTOS that employs patented cache partitioning, memory pools, and safe scheduling to deliver higher CPU utilization than any other certifiable safety-critical COTS RTOS on multi-core processors. First certified to DO-178 DAL A in 1998, Deos combines DO-178C DAL A artifacts with FACE® Technical Standard support that encompasses the Safety Base and Safety Extended Profiles for the Operating System Segment (OSS). The Safety Base Profile features hard real-time response, time, and space partitioning, and both ARINC-653 and POSIX interfaces. The Safety Extended Profile, which adds support for TCP/IP communications, multi-process support, and expanded POSIX capability (80 extra functions), is a superset of the functionality required by the Safety Base and Security Profiles.

SafeMC technology extends Deos’ advanced capabilities to multiple cores, enabling developers of safety-critical systems to achieve best in class multi-core performance without compromising safety-critical task response and guaranteed execution time. SafeMC employs a bounded multi-processing (BMP) extension of the symmetric multi-processing architecture (SMP), safe scheduling, and cache partitioning to minimize cross-core contention and interference patterns that affect the performance, safety criticality and certifiability of multi-core 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 FAA Advisory Circular AC 20-193.

The 68PPC2 is a 3U OpenVPX™ NXP® T2080 PowerPC single-board computer that can be configured with up to two NAI smart I/O and communications function modules. Featuring an NXP QorlQ® T2080 Quad Core e6500 Processor running at 1.8 GHz, and consuming less then 25W, the 68PPC2 is ideally suited for rugged Mil-Aero applications that accelerate deployment of SWaP-optimized systems in air, land, and sea applications. The 68PPC2 comes equipped with eight Mbytes of DDR3 SDRAM and 32 Gbytes of SATA II NAND Flash. It also features PCIe, USB, I2C, TTL, and RS-232 interfaces, as well as an optional SATA II for external access to up to 2 TB of expansion memory.
