Using Formal Verification To Prevent Catastrophic Security Breaches

The news of last week’s Yahoo hack that affected 500-million or so users sent shock waves of anxiety far and wide. It’s not clear yet how the massive data breach occurred or through what means the hackers accessed the network. It could be the chips that drive the network, often vulnerable to attacks on their operational integrity. It’s no surprise, then, that semiconductor companies ar... » read more

Gaps In The Verification Flow

Semiconductor Engineering sat down to discuss the state of the functional verification flow with Stephen Bailey, director of emerging companies at [getentity id="22017" e_name="Mentor Graphics"]; [getperson id="11079" comment="Anupam Bakshi"], CEO of [getentity id="22168" e_name="Agnisys"]; [getperson id="11124" comment="Mike Bartley"], CEO of [getentity id="22868" e_name="Test and Verification... » read more

Customizable Apps – Avoiding The Pitfalls Of EDA Frameworks

For those of us involved with EDA tools in the late '80s and early '90s, the word “frameworks” brings back memories of rigid methodology and use models, coupled with CAD complexity. Cadence and Mentor, among others, proposed the EDA framework as a mechanism to provide design revision management coupled with tool flow control (I can already imagine your eyes glazing over). For some situat... » read more

Formal Has Its Day

As new technologies receive more mainstream attention, it is common for the experts in the area to provide a critical mass of enthusiasm. Formal is in this mode with multiple meetings throughout the year and around the globe. Perhaps one of the most successful of these is the annual Formal Day event put on by Test & Verification Solutions (TVS) based in the UK. This live and online event is... » read more

Can Verification Meet In The Middle?

Semiconductor Engineering sat down to discuss these issues with; Stan Sokorac, senior principal design engineer for [getentity id="22186" comment="ARM"]; Frank Schirrmeister, senior group director for product marketing for the system development suite of [getentity id="22032" e_name="Cadence"]; Harry Foster, chief verification scientist at [getentity id="22017" e_name="Mentor Graphics"], Bernie... » read more

Verification Engine Disconnects

Moving verification data seamlessly between emulation, simulation, FPGA prototyping and formal verification engines may be possible on paper, but it is proving more difficult to implement in the real world. [getkc id="10" kc_name="Verification"] still consumes the most time and money in the design process. And while the amount of time spent on verification in complex designs has held relativ... » read more

The Secret To Good Comedy And SystemC Code Verification… Timing!

The High-Level Synthesis (HLS) of algorithmic code, usually written in SystemC, is steadily gaining ground. However, the verification of this code is still a somewhat mixed-up, ad-hoc process. The situation is improving as new techniques are applied, but it is clear that in-the-trenches evaluation of these solutions on real projects is more important right now than grand visions missing substan... » read more

The Early Bird Catches The Bug Using Formal

It has been suggested that formal might replace simulation, at least in some parts of the design flow. Not likely! The question is, how can formal be layered on top of simulation flows to improve coverage and schedule? The way formal is being used at the larger semiconductor companies is evolving. In many of these companies a small team of hardcore formal experts are employed across differen... » read more

It’s Transition Time

For the past couple of years we've been hearing about the coming onslaught of the IoT, difficulties in scaling device features and a shift left that will redefine verification, debug and software prototyping. It's all happening. Taken individually, these are noteworthy changes. Taken as a whole, they represent a massive repositioning of the semiconductor industry, from architectural explorat... » read more

Reducing Verification Risk With Formal-Based Observation Coverage

An effective measure of verification progress, together with guidance towards design areas remaining untested, requires a precise view of the test coverage achieved. To risk signing off the verification process without understanding the quality of testing raises the specter of post-production device bugs. OneSpin Solution’s patented Quantify technology employs Observation Coverage, which eval... » read more
