These days the verification process starts right when the design process begins, and it keeps going well past the end of the design phase. Simulation is used extensively at every stage of design and can go a long way to help validate a design. However, for many types of designs, especially those that process complex data streams, … Read More

What’s New in CDC Analysis?
Synopsys just released a white paper, a backgrounder on CDC. You’ve read enough of what I’ve written on this topic that I don’t need to re-tread that path. However, this is tech so there’s always something new to talk about. This time I’ll cover a Synopsys survey update on numbers of clock domains in designs, also an update on ways to… Read More
Solving and Simulating in the New Virtuoso RF Solution
Cadence has done a good job of keeping up with the needs of analog RF designs. Of course, the term RF used to be reserved for a thin slice of designs that were used specifically in RF applications. Now, it covers things like SerDes for networking chips that have to operate in the gigahertz range. Add that to the trend of combining RF and… Read More
Essential Analog IP for 7nm and 5nm at TSMC OIP
When TSMC’s annual Open Innovation Platform Exposition takes place, you know it will be time to hear about designs starting on the most advanced nodes. This year we were hearing about 7nm and 5nm. These newer nodes present even more challenges than previous nodes due to many factors. Regardless of what kind of design you are undertaking… Read More
When FPGA Design Looks More Like ASIC Design
I am sure there are many FPGA designers who are quite content to rely on hardware vendor tools to define, check, implement and burn their FPGAs, and who prefer to test in-system to validate functionality. But that approach is unlikely to work when you’re building on the big SoC platforms – Zynq, Arria and even the big non-SoC devices.… Read More
Innovation in a Commodity Market
Logic simulation is a victim of its own success. It has been around for at least 40 years, has evolved through multiple language standards and has seen significant advances in performance and major innovations in testbench standards. All that standardization and performance improvement has been great for customers but can present… Read More
Converter Circuit Optimization Gets Powerful New Tool
DC converter circuit efficiency can have a big effect on the battery life of mobile devices. It also can affect power efficiency for wall-power operated circuits. Even before parasitics are factored in, converter circuit designers have a lot of issues to contend with. Optimizing circuit operation is essential for giving consumers… Read More
Another Application of Automated RTL Editing
DeFacto and their STAR technology are already quite well known among those who want to procedurally apply edits to system-level RTL. I’m not talking here about the kind of edits you would make with your standard edit tools. Rather these are the more convoluted sort of changes you might attempt with Perl (or perhaps Python these days).… Read More
Unexpected Help for Simulation from Machine Learning
I attend a lot of events on machine learning and write about it regularly. However, I learned some exciting new information about machine learning in a very surprising place recently. Every year for the last few years I have attended the HSPICE SIG dinner hosted by Synopsys in Santa Clara. This event starts with a vendor fair featuring… Read More
Simulation and Formal – Finding the Right Balance
Simulation dominates hardware functional verification today and likely will continue to dominate for the foreseeable future. Meanwhile formal verification, once thought to be a possible challenger for the title, has instead converged on a more effective role as a complement to simulation. Formal excels at finding problems… Read More
