DAC Day Three: UVM, Machine Learning And DFT Come Together


The industry and users have a love/hate relationship with UVM. It has quickly risen to become the most used verification methodology and yet at the same time it is seen as being overly complex, unwieldy and difficult to learn. The third day of DAC gets started with breakfast with Accellera to discuss UVM and what we can expect to see in the next 5 years. The discussion was led by Tom Alsop, pri... » read more

Formal Confusion


Semiconductor Engineering sat down to discuss the right and wrong ways to apply formal verification technology with Normando Montecillo, associate technical director at [getentity id="22649" comment="Broadcom"]; Ashish Darbari, principal engineer at [getentity id="22709" e_name="Imagination Technologies"]; Roger Sabbagh, principal engineer at Huawei; and Stuart Hoad, lead engineer at PMC Sierra... » read more

Open Standards For Verification?


The increasing use of verification data for analyzing and testing complex designs is raising the stakes for more standardized or interoperable database formats. While interoperability between databases in chip design is not a new idea, it has a renewed sense of urgency. It takes more time and money to verify increasingly complex chips, and more of that data needs to be used earlier in the fl... » read more

Going Open Source


Open Source often is thought of as an alternative to commercial software licensed using fairly typical business models. For example, variants of open source Linux supplied by companies such as Red Hat charge a subscription for support and maintenance. Maybe there is an opportunity to leverage Open Source alongside commercial EDA software to provide use model advantages and open development f... » read more

Bridging the IP Divide


IP reuse enabled greater efficiency in the creation of large, complex SoCs, but even after 20 years there are few tools to bridge the divide between the IP provider and the IP user. The problem is that there is an implicit fuzzy contract describing how the IP should be used, what capabilities it provides, and the extent of the verification that has been performed. IP vendors have been trying to... » read more

Making Way For Register Specification Software


No one gives much thought to the heating, ventilation and air conditioning registers in the house –– typically, two in each room, one for supply, the other for return. That is, until the lever in each needs to be manually adjusted to modulate the temperature to be hotter or colder, or the seasons change and the filters with them. Alas, registers in hardware design seem to have gotten the... » read more

UVM Register Layer: The Structure


I don’t know about you, but I am looking forward to the day where we won’t even have to go to the doctor’s office for an exam. Instead, we will all have scanners in our homes that will transmit full digital models to our doctors who can then poke, prod, and examine us remotely. This is essentially what the UVM register layer allows and does. The UVM register layer acts similarly by mod... » read more

Verification Facing Unique Inflection Point


The Design and Verification Conference and Exhibition (DVCon) attracted more than 1,100 people to San Jose last week, just slightly less than last year. While a lot of focus, and most of the glory, goes to design within semiconductor companies, it is verification where most of the advancements are happening and thus the bigger focus for DVCon. The rate of change in verification and the producti... » read more

UVM: It’s Organized And Systematic


One of the reasons I like using UVM is its tendency toward an organized structure and uniformity. Some may find it annoying to adhere to such a strict format in UVM, but I think it’s a good way to keep the basics of UVM engrained in your brain. You always want a good foundation and development of strong fundamentals in any endeavor. Verification is no different and UVM hammers the fundamental... » read more

Still Time to Blow Up UVM


Blowing up UVM is something I ran on my own blog a few years ago. Considering not much has changed with respect to UVM – that it continues to dominate verification circles – I figured it’s a discussion worth re-starting. In my mind, it’s not too late to take a few steps forward by blowing up UVM. A little history… the idea to blow up UVM was motivated by a slide snapshot posted to ... » read more
