process
Validates SCA compliance at the architectural and unit
test level.
Generates correct-by construction SCA component
structural source code in C++ (GPP) and C (GPP &
DSP) with a roadmap to VHDL code generation
Generates SCA compliant artefacts such as: XML
descriptor files, compliance test reports and validation
documentation
SCX enables SCA & non-SCA software aspects to be
developed together, integrated early and be thoroughly
tested
Reduces development risk due to its consistent model-
based approach
Results in a faster time-to-market, lower costs, better
software quality and superior compliance for all SCA
waveform and platform code developed using SCX
