Want Automated, Certification-Level RISC-V Verification Coverage?

I feel like an old fool (but where are we going to find one at this time of the day?). Almost everything I hear on the technology front these days causes me to have a knee-jerk reaction along the lines of, “Things have certainly changed since those far-off days when I was a bright-eyed, bushy-tailed, newly-minted engineer!”

As I’ve mentioned before, I … Read More → "Want Automated, Certification-Level RISC-V Verification Coverage?"

Is Jeff Goldblum Hollywood’s go-to person for an on-screen engineer?

Actor Jeff Goldblum recently appeared as a guest host for the Jimmy Kimmel Live! TV show. Kimmel was on vacation. As part of his first-night monologue, Goldblum played piano (he’s an accomplished jazz pianist) and sang a song with references to several of the movies that he’s appeared in over the last four decades. While he was singing, I realized that Goldblum’s … Read More → "Is Jeff Goldblum Hollywood’s go-to person for an on-screen engineer?"

The Moon Needs Its Own Time Zone. Relativity Says It Also Needs Its Own Clocks

A CNN article written by Jackie Wattles and titled “Why scientists say we need to send clocks to the moon — soon” grabbed my attention and quickly sent me down several rabbit holes that involved some ideas in physics that I knew but had not internalized. First, the moon needs its own timekeeping … Read More → "The Moon Needs Its Own Time Zone. Relativity Says It Also Needs Its Own Clocks"

One EDA Tool, One Giant Leap for Hardware: How JITX is Reshaping Circuit Board Design

This week my guest is JITX Co-founder and CEO Duncan Haldane. Duncan and I discuss the challenges of board design and how the benefits of software reuse encouraged the development of JITX, why holistic system design is cornerstone to the JITX software-defined electronics platform, and how you can improve your productivity with the JITX cookbook.

No Slacking! Put Your Sem;colons to Work [Exclamation Mark Goes Here]

I’m still chafing under the impositions imposed by the punctuation police. I speak of those who don the undergarments of authority and stride the corridors of power. Those despicable despots who dictate I can no longer terminate the titles to my columns with exclamation marks, all the time muttering inscrutable incantations to their SEO gods. Fortunately, I’m not bitter. … Read More → "No Slacking! Put Your Sem;colons to Work [Exclamation Mark Goes Here]"

A game-changer for IP designers: design-stage verification

Sponsored by Siemens Digital Industries Software

In this new technical paper, you’ll gain valuable insights into how, by moving physical verification earlier in the IP design flow, you can locate and correct design errors sooner, reducing costs and getting complex designs to market faster. Dive into the challenges of hard, soft and custom IP creation, and learn how to run targeted, real-time or on-demand physical verification with precision, earlier in the layout process.

No, I was trying to point out that Verilog may be reaching end of life for other reasons. Farewell.

Sorry, Max. All I said was: “SVH validates your HDL code. It makes sure that your code makes sense syntactically, that it makes sense semantically, that it adheres to corporate coding styles, that it takes care of function safety, that it’s aware of vulnerability issues, that… the list goes ...

Hi Karl -- I'm not sure what point you are trying to make -- you say that there's no way to increase performance meaningfully using edge-triggered flip-flops. OK, but what does that have to do with this column? I don't mention performance anywhere. All I said was: "SVH validates your ...

So. here goes: 1) There is no way to increase performance meaningfully using edge triggered flip-flops. Clock frequency, skew, and heat dissipation are the prime factors. Exceptions include functional blocks, including block memories. Note that true dual port memories are key, but the separate read and write clocks are more tolerant ...
