Managing Initial State to Head Start Formal Verification

Wouldn’t it be nice to get a head start on some things in life? How great would it be to just be able to walk straight to the front of any queue you find yourself in? For me, I’d like a head start on those long flights from the UK to California. If I could start them somewhere over the Rocky Mountains, then it would be a much more pleasant journey… aside from the mountain waves turbulence! While money, fame or just downright rudeness can potentially get you to the front of a queue, I’m going to have to wait for someone to invent teleportation to cut down that journey time.

Artificial Intelligence, let us get the math right first!

Artificial intelligence is a hot topic these days and therefore doesn’t require a repeat of the current and future potential uses for AI. For most people it means technology advancements on the software side but If you ask people who are very close to this technology domain, building your own optimized hardware chips is where significant part of the competitive edge lies.

Don’t have a Meltdown over a Spectre in your SoC

You may be concerned about the widely published Spectre and Meltdown vulnerabilities affecting most processors, and if your phone and computer are OK. Or more importantly, if you are designing or verifying SoCs, do you have a specter in your design? Let’s first look at what these two vulnerabilities are and how they are affecting your system.

Deep or Broad : Let’s settle this once and for all!

Have you ever witnessed two passionate industry experts debate fundamental approaches of verification? They bring their decades of experience, hundreds of bugs uncovered, and countless successes and failures in order to establish intellectual dominance. Unfortunately, for most of us, the observers, these debates are usually prematurely interrupted by a reality check: a pointy-haired manager who urges them to “take it offline” or we all get “kicked out” of a conference room.

Corner case bugs – Formal got you covered

Imagine the scene. It’s Friday night, and you’ve decided to relax and watch a movie. Given the overwhelming amount of choices, you’ve already spent over an hour watching trailers to choose the movie and you’re finally almost ready to go. All that’s left is the popcorn. You go over to the microwave and get it going. For a little while nothing happens, but then you start to hear the pops, slowly at first but then much more rapidly before beginning to taper off. You then have to ask yourself: When do I stop? This is a big question. Take it out too soon and you’re going to break your teeth on those unpopped kernels. Leave it in too long and you risk burning it. How can you know if its popped long enough?

Interconnect Traffic Jam on your SoC

Interconnect on a System on Chip (SoC) is like the road network. There is a lot of it but it still doesn’t go everywhere and traffic jams mean that even if there is a road, you may not be able to get to your destination.

Tearless Formal Verification

Cooking can be a necessity, hobby or calming therapy depending on whom you talk to. Personally speaking, I cook occasionally but even when I am not cooking and I am just a mere silent admirer of this amazing process, onion peeling/cutting/chopping brings tears to my eyes 😀 There are few tricks that one could use to avoid or minimize tears while peeling onions. Some of these tricks work, some don’t.
