Verification of ML IP and Specman—Our Hackathon Project

By teamspecman | 15 Jan 2019

If you are lucky enough and your company spends a few working days each year on a Hackathon, you must know that it is usually a lot of fun. The latest 2018 Hackathon in Cadence was all about Machine Learning. We, in Specman R&D, debated a bit around how to approach the topic since Machine Learning means a lot of different things in our industry. Take a look at the following interesting article: Where ML works best in...

Renesas Brings Their Legacy Testbench Up to Speed Using the Cadence Verification Suite

By XTeam | 24 Dec 2018

Recently, Renesas Electronics Corporation faced a challenge. They were developing a new data conversion block, one that included an AHB bus bridge, which would be attached to a pre-existing DMA IP core. There was also a complicated finite state machine involved in this new block. Renesas didn’t have a whole lot of time on their hands—they needed a quick turnaround time, but only had a limited amount of engineers to accomplish...

Adding a Patch Just in Time! — Or Can You Really Allow Yourself to Waste So Much Time?

By teamspecman | 30 Aug 2018

One animation video - Patch Like The Wind - is worth a thousand words :) If you don’t use Specman or don’t use Specman correctly, you spend most of your time waiting for compilation to finish. One of the most frustrating (and common…) scenarios is when you know more or less what the fix should be (such as, “wait additional cycle before sending” or “the variable should be int and not uint”) and the fix can be...

Tales from DAC: How Altia Systems Used Xcelium to Bring New Life to Virtual Meetings

By XTeam | 31 Jul 2018

We’re going to take a wild guess and say you’ve been in a meeting before. Maybe it was a virtual meeting—but those never really feel the same in person, do they? Attending a virtual meeting can feel cold and impersonal, especially since you can barely see everyone else. Everyone is there except you—and even then, saying you’re “there” is a bit of a stretch. Nowadays, though, there’s technology to remedy this problem...

Tales From DAC: How Syntiant Went From Zero to Tapeout in Six Months

By XTeam | 23 Jul 2018

Here’s something to chew on: Syntiant is an AI startup involved in deep learning technology and semiconductor design. Their goal is to create exceptionally low-power designs for always-on devices, like those used in speech detection. Syntiant went from empty air to tapeout in six months. That sounds hard to believe, but it’s true. They got their first venture-capital funding in October of 2017, taped out initial...

UVM-ML- Managers’ Freedom of Choice

By teamspecman | 28 Jun 2018

Freedom of choice is a term we hear a lot, especially in the last 10 years. It is defined in wikipedia as “an individual's opportunity and autonomy to perform an action selected from at least two available options…”. Is having many choices always a good thing? Well, usually it is- who would not want to live in a world where s/he has options and can make choices? However, there are also downsides to having multiple...

Microsemi has been evaluating a unique feature in Xcelium System Verilog UVM Dynamic Test Load for some time now, and they shared their thoughts on it in a paper presented at CDNLive San Jose April 2018. One of the fields Microsemi operates in is the realm of optical networking. In optics, a given sensor’s input can vary wildly, but the way the input is processed is largely the same. Thus, a wide variety of tests are...

Empowering Generation - Range Generated Fields (RGF)

By teamspecman | 31 May 2018

Specman constraints solver process consists of a series of reductions and assignments . It reduces the range of the field value based on the constraints, and then assigns to it a random value from the reduced range. After assigning one field, the range of all connected fields is reduced accordingly, and the process continues until all fields are assigned. A new feature added in Specman 18.03 – Range Generated Fields...
