FPGA Verification with Assertions: Why Bother?


This paper provides a practical, easy, step-by- step set of instructions on how to add assertions to your RTL design. By following the simple guidelines provided in this paper you will benefit by cutting simulation debugging time in half, as well as finding very complex bugs that are likely to escape traditional simulation without assertions.

Automated Assertion-Based Verification Methodologies For IP And SoC Development


The rapid growth in complexity and size of modern System on Chip devices (SoCs), along with the expense of developing these ICs, has driven the need for design reusability. Today, SoC designs are typically built as a collection of individual IP (Intellectual Property) blocks stitched together with glue logic. These IP can be sourced from multiple design teams, including many 3rd-party teams. So... » read more

IP/SoC Verification With Assertions


There's been a lot of excitement here in Silicon Valley these past weeks with the opening of the new 49ers stadium. I've always found it amazing to see how so many complex, fundamentally different technologies — mechanical, electrical, HVAC, plumbing, audiovisual, food catering, etc. — can be put together to create a functioning ballpark. It all but takes a mastermind to bring all these eng... » read more

The Assertion Conundrum


It is well documented and widely agreed that assertions can provide a tremendous benefit to design and verification teams by reducing and even eliminating debug – but their use is still not ubiquitous. Part of the reason is that assertions cannot be picked up casually, noted David Larson, director of verification at [getentity id="22150" e_name="Synapse Design"]. “This is because asserti... » read more

Is Formal Ready To Displace Simulation?


In part one of this roundtable, the panelists talked about the recent changes that have brought formal to the forefront of verification and discussed the challenges that the UVM have brought to formal. In part two, the panel focused on the subject of coverage and the ways in which formal coverage can be combined with simulation. In this segment we start exploring the impact that sequential equi... » read more

Extending UVM To Analog


As SoC complexity has grown, so too has the need to model the analog/mixed-signal content in a similar way as the digital content to make simulation easier. One way to do this is within the context of the Universal Verification Methodology (UVM). In fact, this can and is being done today with UVM as it stands, according to a number of industry sources. However, there is also growing interest... » read more

Localized, System-Level Protocol Checks And Coverage Closure


Broadcom recently developed a unified, scalable, verification methodology based on the Veloce emulation platform. In order to test this new environment, they ran a test case, which proved that they can take assertions, compile them into Veloce, and verify that they fire accurately. In so doing, they were able to provide proof of concept for their primary goal: the creation of an internal flow t... » read more

Tech Talk: Debugging IP


Just because IP is standard doesn't mean it will function as expected in a complex SoC. Ravindra Aneja, senior technical marketing manager at Atrenta, looks at what needs to be done to make sure everything works together. [youtube vid=wlDabbrF2zU] » read more

Formal Is Set To Overtake Simulation


There has been a significant psychology change in the area of formal verification over the past couple of years. It’s no longer considered a fringe technology, and it’s no longer considered difficult to use. In fact, it has become a necessary part of the verification process. Semiconductor Engineering sat down with a panel of experts to find out what caused this change and what more we c... » read more

Executive Viewpoint: Bootstrapping A Startup


This story begins as many new developments have in the EDA industry. A designer, or verification person in this case, by the name of Yuan Lu, was working in a semiconductor company. He manually developed a lot of assertions for use in formal verification. He found they also were useful in a simulation environment, but he had great trouble convincing his fellow workers to develop similar ass... » read more
