Automotive designs demand a high level of fault tolerance, and one of the methods to achieve this is to use error correcting codes (ECC). This Wikipedia page ECC Memory gives a flavor, though that article concentrates on memory and we are interested in wider applications using a form of forward error correction. This technique … Read More
News of cyberattacks is routine these days in spite of the security mechanisms built into widely used electronics systems. It is not surprising that entities involved with ensuring safe and secure systems are continually working on enhancing encryption/decryptions mechanisms. Recently NIST standardized cryptography algorithms… Read More
The use of safety-centric logic design techniques for automotive applications is now widely appreciated, but did you know that similar methods are gaining traction in the design of enterprise-level SSD controllers? In the never-ending optimization of datacenters, a lot attention is being paid to smart storage, offloading… Read More
The ISO 26262 standard defines four Automotive Safety Integrity Levels (ASILs), from A to D, technically measures of risk rather than safety mechanisms, of which ASIL-D is the highest. ASIL-D represents a failure potentially causing severe or fatal injury in a reasonably common situation over which the driver has little control.… Read More
Safety is a big deal these days, not only in automotive applications, but also in critical infrastructure and industrial applications (the power grid, nuclear reactors and spacecraft, to name just a few compelling examples). We generally understand that functional blocks like CPUs and GPUs have to be safe, but what about the … Read More
Formal methods are a vital complement to other tools in the verification arsenal, but they’re not without challenges. One of the more daunting is the “inconclusive” result – that case where the tool seems to be telling you that it simply gave up trying to figure out if a particular assertion is true or false. Compounding the problem,… Read More
Once in a while I come across a vendor-developed webinar which is so generally useful it deserves to be shared beyond the confines of sponsored sites. I don’t consider this spamming – if you choose you can ignore the vendor-specific part of the webinar and still derive significant value from the rest. In this instance, the topic is… Read More
The old one-size-fits-all approach doesn’t work anymore for DDR4 memory controller IP, especially when addressing the enterprise segments, or application like servers, storage and networking. For mobile or high end consumer segments, we can easily identify two key factors: price (memory amount or controller footprint) … Read More
In the past year, I’ve written numerous articles that have a common theme: the security world is badly broken as crypto schemas developed in the 90’s are no defense for today’s sophisticated hackers. For the most part, my blogs have been very well received, and have been picked up and posted by multiple sites and publications worldwide.… Read More
For those among you who have read my previous SemiWiki articles, you will no doubt see a theme: the security of our connected world is badly broken, and for the bad guys, violating our online lives – both business and personal – is as easy as taking candy from the proverbial baby.… Read More
