Synergy Software Package (SSP) Components

SSP components are tightly integrated, optimized, tested, documented, and maintained by Renesas. A layered architecture enables developers to write their application with the Application Framework using common APIs, or by directly connecting to the device driver level as needed. Learn the functions of each SSP component here.

Software Quality

Renesas has established a Software Quality Assurance (SQA) process for the SSP to cover the necessary Testing and Software Development Life Cycle (SDLC).

SSP quality is tracked and measured using combinations of unit, functional, integration, performance, regression, dynamic, and static analysis tests. To ensure high quality, production grade Software, SSP is developed and tested to ensure adherence with the four quality metrices

  • Meet coding standards
  • Maintain low code complexity
  • Build cleanly
  • Comprehensive module and system level testing
