TESTiNg
industry-proven SIL simulator (VEOS),
along with integrated scenario-based
testing for AV software stacks - ranging
from SIL to HIL testing. The modular,
scalable cloud-based automated testing
process allows for integrated analysis of
tests/scenarios while allowing the user to
configure and scale the hundreds or
thousands of test executions that may be
required for AV system validation in the
cloud. The models, tests, parameters, and
other test assets are fully re-usable across
SIL and HIL testing, using SIMPHERA. The
tests can be automated intelligently (via
the XIL-API) to evaluate SUT performance
across multiple iterations of parameters or
scenarios, using automated Key
Performance Indicators (KPI) that allow for
direct evaluation of test results on-the-fly.
This type of testing allows for test suite
design to fully accomplish the functional
safety and performance evaluation needed
for standards like ISO-26262/IEC-61508.
SIMPHERA also integrates with the BTC
ScenarioPlatform that creates scenarios
and generates and evaluates tests based
on coverage. The high level of abstraction
makes it possible to express thousands of
test cases with just one abstract scenario,
the companies claim. BTC's automated test
generation functionality uses advanced
technology such as model checking, AI,
and intelligent weakness detection, which
allows test cases to be generated based on
statistical methods and meaningful
coverage metrics. Compared to random or

Jace Allen is a 32-year SAE member who has contributed
many technical papers, advancing the core technologies for
embedded systems development and testing. dSPACE in the
last several years has been very involved in conferences
covering all of SAE's mobility sectors.
" brute force " test generation approaches,
this strategy " considerably " reduces the
amount of test data and delivers clear
metrics, says BTC, even regarding future
homologation criteria.
" It's the same methodology we've talked
about for SIL and HIL - test asset re-use, "
Allen explained. " I can define my sensors,
my vehicles, my scenario, the interface to
my SUTs [systems under test] and then run
whatever simulations I want so that I can
find those edge cases, so that I can
evaluate my AV-system safety according to
SOTIF [Safety of the Intended
Functionality] and so forth. " n
