Universal Verification Methodology Running Out Of Steam

By Ann Mutschler - 30 Jul, 2020 - Comments: 2

For the past decade or so, the Universal Verification Methodology (UVM) has been the de facto verification methodology supported by the entire EDA industry. But as chips become more heterogeneous, more complex, and significantly larger, UVM is running out of steam. Consensus is building that some fundamental changes are required, moving tools up a level of abstraction and making them more ag... » read more

Open-Source Verification

By Brian Bailey - 30 Jul, 2020 - Comments: 1

Ask different people what open-source verification means and you will get a host of different answers. They range from the verification of open-source hardware, to providing an open-source verification infrastructure, to providing open-source stream generators or reference models, to open-source simulators and formal verification engines. Verification is about reducing risk. "Verification is... » read more

Methodology Vs. Problem-Solving

By Hagai Arbel - 22 Jul, 2020 - Comments: 1

When I was 18, I bought a Vespa ’67: the famous Italian scooter. It was already very old then, totally beaten-up, but luckily I had a friend who owned an auto-repair shop, and he was kind enough to give me some access at night. For several weeks, I taught myself the art of metal bodywork, ending up with a beautiful metallic sky-blue ‘67 Vespa. God, I loved that machine! Then one day, ... » read more

The Increasingly Ordinary Task Of Verifying RISC-V

By Ann Mutschler - 03 Jun, 2020 - Comments: 0

As RISC-V processor development matures and its usage in SoCs and microcontrollers grows, engineering teams are starting to look beyond the challenges of the processor core itself. So far, the majority of industry verification efforts have focused on ISA compliance to standardize the RISC-V core. Now the focus is shifting to be how to handle verification as the system grows, especially as this... » read more

A Different View On Debugging

By Hagai Arbel - 01 Jun, 2020 - Comments: 0

The classic approach to improve an engineering task that is becoming too complex due to its size and detail is to raise the abstraction of design representation. In this way we plan cities, build aircraft and plan 500M gate SoCs. For example, there is no way an ASIC design could go beyond a few thousand logic gates without shifting abstraction to the Register Transfer Level (RTL) and leveragin... » read more

Using Processor Trace At The System Level

By Ann Mutschler - 23 Apr, 2020 - Comments: 0

The race to process more data faster using less power is creating a series of debug challenges at the system level, where developers need to be able to trace interactions across multiple and often heterogeneous processing elements that may function independently of each other. In general, trace is a hardware debug feature that allows the run-time behavior of IP to be monitored. More specific... » read more

Simulation: Balancing Speed And Debug

By Rohit Narkar - 09 Apr, 2020 - Comments: 2

There’s an old saying about simulation: “It’s all about the need for speed.” Simulation is the core technology for functional verification of semiconductors, and the demand for higher runtime performance never ebbs. Larger chips require more complex testbenches and much larger test suites since verification grows exponentially with increase in design size. With the diminishing return an... » read more

Why Is PSS So Important?

By Ed Sperling - 25 Feb, 2020 - Comments: 0

Robert Hoogenstryd, product marketing manager at Mentor, a Siemens Business, talks about the new testbench verification language standard, what are the big advantages of using PSS, what kinds of challenges this language solves, and how much time this approach can save. » read more

Context-Aware Debug

Moses Satyasekaran, product manager at Mentor, a Siemens Business, examines the growing complexity of debug, which now includes software, power intent and integration, multiple clocking and reset domains, and much more, where the limitations are for debug, and how automotive, functional safety and mixed signal affect the overall process. » read more

Making Sure RISC-V Designs Work As Expected

By Ann Mutschler - 30 Jan, 2020 - Comments: 0

The RISC-V instruction set architecture is attracting attention across a wide swath of markets, but making sure devices based on the RISC-V ISA work as expected is proving as hard, if not harder, than other commercially available ISA-based chips. The general consensus is that open source lacks the safety net of commercially available IP and tools. Characterization tends to be generalized, ra... » read more
