    What is WiGig

    WiGig is the name given to a high-speed multi-gigabit wireless communications standard over unlicensed 60GHz radio frequency band established by the Wireless Gigabit Alliance in 2007. Since then it has become part of the WiFi Alliances and established as one of the IEEE 802.11ad protocol. As part of the WiFi Alliances, WiGig tri-band-enabled devices will operate in the 2.4, 5 and 60GHz radio band.

    After reading the rest of this blog, you might guess the truth, which is that my "designing" skills go back to the 8086 processor! In this blog, I have used a 64-bit register (Well, I could make it 16-bit, but…)  in the example, just to show that this issue is still relevant today.

    At any rate, the e verification issue that I describe here seems to be a common issue for many users.

    In this week's Whiteboard Wednesdays video, Herbert Rivera-Sanchez discusses the Cadence Verification IP (VIP) Ease of Use Project. This project addresses three main areas of concern: works out of the box, provides consistent integration and provides basic training to quickly bring customers to a productive level in a short time.

    A customer working on a VIP component identified that the performance of one of their protocol checkers, written in ‘e’, is significantly worse than the performance of the competing solutions. Profiler reports of a representative test case pointed to a few complex methods, which consumed about 90% of the time. What stood out in these methods was the use of the pop0() pseudo-method on a couple of list buffers. This…

    This year’s Mobile World Congress (MWC) in Barcelona, March 2-5, should be the largest, most exciting MWC ever. I’ve been going since 2006, and I’ve seen the show outgrow the old convention area and now, with over 1900 exhibitors, outgrow the new Fira Gran Via. We’re lucky that the Tensilica group has been going for a long time, as getting a space to exhibit now is almost impossible.

     Most engineers are familiar with the “Butterfly effect” – the notion that a small change can result in enormous repercussions in the future. A similar notion applies in verification. We might expect waveform traces to match between, say, an RTL simulation and post-synthesis gate-level design for a certain signal, but we want to be sure. We want to ensure no small…
