Benefits• Provides consistent concept and design solution for SoC

connectivity specification• Single source of connectivity specification for

documentation and implementation generation• Automatic detection of incorrect connectivity

specification• Increased quality of connectivity specification• Real time visibility and debugging of connectivity data• Updating database structure with less effort due to

generation• Improved Time to Market

Results

© Accellera Systems Initiative 21

Infineon Connectivity platform is rolled out and is productively used for the development of Infineon Automotive Micro-Controllers

Using this approach, 95% connectivitycoverage was achieved even before the specification release milestone of Automotive Controllers

Pilot phase of the Infineon Connectivity platform is executed for Infineon Industrial Micro-Controllers
