Problems faced by embedded developers


Time to market is important

Only 38% of projects are on time 62% of projects are late! Every year its getting worse ...


Choose your microcontroller wisely

Many chips are similar Ecosystem is important Not all ecosystems are equal ;-)


SOMNIUM® DRT is the solution


SOMNIUM® DRT - Professional C/C++ development environment

Save memorysmaller ROM/RAM device, lower cost designs

Save moneyfaster time to market, optimize BOM costs

Increase performancemore features, “do more with less”

Save energyhigher quality design, reduce lifetime costs


SOMNIUM® DRT :The professional C/C++ development environment Advanced Eclipse based IDE

Modified CDT for usability features State of the art debug and trace Importers to support legacy projects

and semiconductor partner enablement Windows, Linux and macOS hosted

Advanced C/C++ code generation Validated with ISO26262 testsuite Patented resequencing optimizations Smaller, faster, energy efficient code No source code changes required

Technical support and product updates Direct from SOMNIUM's customer engineering team


Rigorous approach to correctness & quality

To our best knowledge no other tools vendors apply this rigour Tests are applied on-host (simulated) and on-target (real silicon) Tested to destruction ! Flash ROM wears out after ~2 months of our testing 3 axis testing : size and performance and energy

DejaGNU tests: GNU compatibility conformance SolidSands SuperTest: C/C++ standard conformance and functional correctness

Over 136,000 individual tests per Cortex-M variant (~4 hours on-host run time) NULLSTONE for C: optimization test suite

Almost 40,000 individual tests (over 48 hours run time if using one board at a time) EEMBC® Autobench™ and CoreMark™ Over 5,000 examples and demos from our semiconductor partners SOMNIUM proprietary test suite

Well placed for future certification (e.g. ISO26262) Moving forwards not backwards

Full regression testing to ensure each release is better than the last


DRT recognizes that memory is the bottleneck

SOMNIUM® DRT optimizes for the whole system

It dominates performance and cost


Measuring energy consumption

SOMNIUM are members of the EEMBC® Automotive Subcommittee and use their industry standard benchmarks.

We measure energy, measured to the uJ using the high accuracy EEMBC EnergyMonitor™

EEMBC CoreMark™ is used to demonstrate the usable performance of a processor system running typical algorithms including list processing (to stress test data accesses), matrix manipulation (to stress test and mathematical operations, and state machines (to stress test complex control flows).


Wide range of performance and energy options

Higher performanceLower energyMore expensive

Extreme performanceHigher energyMore expensive

Baseline device● Good performance ● Low energy consumption● Low cost


DRT is benchmark proven: Smaller, faster, lower energy

EEMBC® CoreMark® built with DRTUp to 54% higher performance

Up to 44% lower energyUp to 14% smaller ROMUp to 21% smaller RAM

Unique project importers

DRT QuickFix identifies issues and applies fixes Bad launch configurations Host OS specific directory/filenames Bad/inconsistant configuration options

Import and automatic conversion from Atmel Studio/START (GPDSC format) Atollic TrueSTUDIO KDS 2, KDS 3x CodeWarrior for MCUs 10.6 (GNU projects) CodeWarrior for MCUs (non GNU projects) LPCXpresso/MCUXpresso SW4STM32, STM32CubeMX

More importers on the roadmap ...


Integrated lightweight C/C++ static analysis

“As you type” detection of errors, Quick Fixes for common issues Sensible default configurations Checks for user configurable for customized coding/naming conventions


State of the art debug : Live memory view

No impact on the target - no breakpoint, no extra code, no timing or performance impact Full C/C++ typecasting


State of the art debug : Cortex-M0+ MTB trace

No need to read the ARM hardware documentation Automatically configured

no need to specify address of buffer


State of the art debug : Fault analysis

No need to read the ARM hardware documentation Fault diagnosis – extract and decode, navigate source code


State of the art debug: RTOS aware

Inspect and select each thread Wittenstein plugin to inspect synchroniziation objects (mutex etc.)


Integrated Percepio Tracealyzer

Integrated into DRT for FreeRTOS and Micrium uCOS/III RTOS trace and analysis

Founding member of the Embedded Tools Alliance

A collaboration of industry-leading independent embedded system vendors

We help customers select the best components from a number of different suppliers, safe in the knowledge that the individual components are of

the highest quality, proven to work together, and do exactly what's required so the customer can concentrate on their development work

rather than fighting with a disparate set of legacy tools and environments
