Automated, Realistic Performance Analysis for Your SoC

Wednesday, June 22nd, 2016

We have a saying here at Breker that the fundamental job of any EDA company in the functional verification space is to “find more bugs, more quickly.” A good verification solution increases design quality by finding more bugs, improves time to market by closing verification faster, or reduces project cost by requiring fewer resources. A great verification solution, which we strive to offer, does all three. Accordingly, we talk a lot about the type of design bugs we can find with less time and effort than traditional methods.

We have another saying at Breker: “A performance shortfall is a functional bug.” A lot of people differentiate between these two cases, but we don’t agree. The specification for your SoC describes its performance goals as well as its functionality. Not meeting your requirements for latency or throughout can render your SoC unsellable just as surely as a broken feature. So we also talk a lot about how our portable stimulus techniques generate test cases for performance verification.


Performance Verification: Bringing Your SoC to Its Knees

Wednesday, October 22nd, 2014

For those unfamiliar with the expression in the title, bringing someone (or something) to its knees means making it submissive. It’s a metaphor possibly derived from the act of hitting someone so hard that his knees buckle and he falls to a kneeling position. Why such a nasty term to start this post? Because when you want to verify the performance of your SoC you want to stress every aspect of it. You want to be mean to it. You want to bring it to its knees.

The most common way to do this is to run production software (operating systems plus applications) on a virtual prototype, a high-level system model created by architects before RTL implementation begins. This is not easy; it takes effort to set up workloads that will stress the design and often production software is not ready at this early stage of the SoC project. Further, this verifies only the high-level model, but RTL simulates too slowly to replicate the same tests, or often to boot the operating system at all.


Breker and Carbon Team Up to Provide Fast, Accurate SoC Verification

Tuesday, September 23rd, 2014

This morning, our good friends at Carbon Design Systems announced a new Web portal to provide system-level solutions for system-on-chip (SoC) developers. The Carbon System Exchange provides a wide range of Carbon Performance Analysis Kits (CPAKs), pre-built systems or subsystems with software at the bare metal or operating system level. CPAKs are key building blocks for SoC teams creating complete virtual prototypes for their designs.

Breker is one of nine announced IP and EDA partners who are working with Carbon to create new CPAKs or enhance current offerings. Some partners, such as ARM, Arteris, and Cadence, are providing processor models or other forms of IP commonly found in SoCs. Others, such as Kozio and Breker, are providing software to run on the CPAKs. As you might expect, what we’re actually providing is not a fixed set of software, but rather the ability for CPAK users to generate multi-processor, multi-threaded, self-verifying C test cases.
