NetSpeed has developed NocStudio, a front end optimization design tool helping architects to create SoC architecture bridging the gap with the back end, floor planning and place and route. At the chip level, NocStudio generates a cache-coherent Network-on-Chip (NoC) allowing interconnecting the various CPU, GPU or Acceleration engines (the Cache-Coherent Clusters) with the I/O-Coherent and Noncoherent Agents by the means of Multiple Cache-Coherent Controllers. NetSpeed Gemini coherent NoC is high performance, scalable, and highly configurable for a wide range of applications and provides multiple benefits like routing and channels optimization, much easier place & route and lower power consumption.

But coherency is all about sharing and there is a complex set of protocols to make sure that sharing happens correctly. A bug in any part of the execution can bring down the complete scheme and product. In that sense, NetSpeed’s Gemini NoC is also an additional IP function which needs to be extensively verified. Let’s see how NetSpeed has addressed the verification challenges linked with this highly configurable coherency IP.
