About nosnhojn

I've been working in ASIC and FPGA development for more than 13 years at various IP and product development companies and now as a consultant with XtremeEDA Corp. In 2008 I took an interest in agile software development. I've found a massive amount of material out there related to agile development, all of it is interesting and most of it is applicable to hardware development in one form or another. So I'm here to find what agile concepts will work for hardware development and to help other developers use them successfully. I've been fortunate to have the chance to speak about agile hardware development at various conferences like Agile2011, Agile2012, Intel Lean/Agile Conference 2013 and SNUG. I also do lunch-n-learn talks for small groups and enjoy talking to anyone with an agile hardware story to tell! You can find me at neil.johnson@agilesoc.com.

Goodbye AgileSoC.com… For A While

On Friday I decided I could use a break from the blog so I’m going to step away for a bit. Not exactly sure for how long, but it might be a while. Or maybe not. We’ll see. Meanwhile, you’ll … Continue reading

The Key To Test-driven Development of RTL

For me, this is a very exciting post because I think I’ve made some pretty important headway regarding TDD for hardware designers. My big side project as of late has been a real pilot dedicated to using TDD to write … Continue reading

The Starting Point for Agile Hardware (That No One Thinks About)

It should be obvious by now that I don’t mind paddling against the current. And I don’t mind suggesting a rethink of “best practices” we use in hardware development. But then there’s the practices that even for me are touchy subjects, where I know … Continue reading

The Goal Of An Agile Hardware Team

Considering there’s been lots of new visitors to AgileSoC.com the last few months, I figured now would be a good time to (re)welcome everyone with a reminder of why we’re all here!

Agile Is More Than Just Concurrent Development

Considering SoC development requires several disciplines and considering our history of specializing and siloing these disciplines, it’s easy to see why people fall into the trap of equating agile development with concurrent development. But they aren’t the same.

Now Is Not The Time To Be Practical

They call them comfort zones for a reason, it’s because they’re comfortable. I don’t like being in my comfort zone because when I get comfortable I fail to recognize when a change is necessary. I start framing uncomfortable change as impractical, then concoct seemingly logical arguments to avoid … Continue reading

Agile IC Methodology From Sonics

Here’s a marketing video posted yesterday from Sonics about an Agile IC Methodology they’re promoting in the run-up to ARM TechCon. Normally I might not post stuff like this directly on AgileSoC.com but I’m making an exception because one of the people … Continue reading

Now What?

You’ve started doing TDD or unit testing your systemverilog code with SVUnit, your defect rate is down and you’re producing better code. You’re at the point where your experience could benefit the rest of your team but you’re not sure how to get the point … Continue reading

Stepping Through an RTL Unit Test

Pretty much every testbench I’ve ever built, used or seen has a free-running clock that’s driven within a while or forever loop. Not much can happen without the clock in a synchronous design so defining the clock logic is usually the first and … Continue reading

TDD for Design Proof-of-Concept

It’s finally time to see if TDD is a viable technique for writing RTL with verilog. But first, a little backstory… For the Agile2014 conference in Orlando this past summer, Soheil and I built an Agile hardware/software co-development demo using a Xilinx … Continue reading
