In last week’s post, we discussed in detail how Breker’s TrekSoC and TrekSoC-Si products can verify the performance of your SoC by stressing every aspect of its functionality. Shortly before that, we announced a partnership with Carbon Design Systems to complement their fast, accurate processor models with TrekSoC. About two months ago, we introduced the new Coherency TrekApp and described how it can verify multi-processor cache coherency with minimal effort.
You can see a strong theme here: multi-processor SoC designs, fast simulation models, automatic generation of multi-threaded, multi-processor test cases, and test cases powerful enough to gather realistic performance metrics from pre-silicon simulation. But what if you don’t have multiple processors or caches in your SoC design? There’s a clear sense emerging in the industry that more and more chips are becoming multi-processor SoCs, and most of these will require cache coherency for the CPU clusters and beyond. Let’s explore this topic more in this post.
