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.

Software Qualification

Renesas has established a Software Quality Assurance (SQA) process for the SSP to cover the entire Software Development Life Cycle (SDLC), from early market requirements validation to software verification and maintenance. Every element of the SSP is defined by and tested to meet these requirements.

SSP quality is tracked and measured using combinations of unit, functional, integration, performance, regression, dynamic, and static analysis tests. To ensure the Synergy SQA process is verifiable and produces quantifiable results, five software quality metric categories must be met for a SSP release:

  • Meet coding standards
  • Maintain low code complexity
  • Have traceability to requirements
  • Build cleanly
  • Achieve full test coverage of all code
