SoC compiler puzzle

Defacto SoC Compiler whose 9.0 release was announced recently automates the SoC design creation from the first project specifications. It covers register handling, IP and connectivity insertion at RTL, UPF and SDC file generation right to logic synthesis. As part of the generation process of RTL and design collaterals, basic… Read More

Defacto SoC Compiler

I read the semiconductor press, LinkedIn and social media (Twitter, Facebook) every morning along with an RSS feed that I setup, staying current on everything related to using EDA tools to make the task of SoC design a bit easier for design teams. A recent press release announced a tool called SoC Compiler, so my curiosity was piqued… Read More

Defacto CEO Interview Chouki Aktouf

“For more than 18 years, we never stopped innovating at Defacto. We are aware of EDA Mantra “Innovate or Die!”. Innovation is in our DNA, and we never stopped adding new automated capabilities to the SoC design community to help facing complexity and cost challenges, which increase every year.”

Before founding Defacto… Read More


Power in Test at RTL Defacto Shows the Way

Power in Test at RTL Defacto Shows the Way

scan chains crossing power domainspng

In the early days of Atrenta I met with Ralph Marlett, a distinguished test expert with many years of experience at Zuken and Recal Redac. He talked me into believing we could do meaningful static analysis for DFT-friendliness at RTL. His work with us really opened my eyes to the challenges that test groups face in integrating their… Read More

Mont Blanc

I’ve talked before about how Defacto provides a platform for scripted RTL assembly. Kind of a rethink of the IP-XACT concept but without need to get into XML (it works directly with SV), and with a more relaxed approach in which you decide what you want to automate and how you want to script it.

They’re hosting a webinar on May 28th 10-11am… Read More

STAR RTL design builder

I’ve talked with Defacto on and off for several years – Chouki Aktouf (CEO) and Bastien Gratreaux (Marketing). I was in a similar line of business back in Atrenta. Now I’m just enjoying myself, I’ve written a few blogs for them. I’ll confess I wondered why they wouldn’t struggle with the same problems we’d had. Script-driven RTL editing,… Read More


Another Application of Automated RTL Editing

Another Application of Automated RTL Editing
by Bernard Murphy on 03-13-2018 at 7:00 am

DeFacto and their STAR technology are already quite well known among those who want to procedurally apply edits to system-level RTL. I’m not talking here about the kind of edits you would make with your standard edit tools. Rather these are the more convoluted sort of changes you might attempt with Perl (or perhaps Python these days).… Read More


Analysis and Signoff for Restructuring

Analysis and Signoff for Restructuring
by Bernard Murphy on 08-29-2017 at 7:00 am

For the devices we build today, design and implementation are unavoidably entangled. Design for low-power, test, reuse and optimized layout are no longer possible without taking implementation factors into account in design, and vice-versa. But design teams can’t afford to iterate indefinitely between these phases, so they… Read More


Design Deconstruction

Design Deconstruction
by Bernard Murphy on 06-19-2017 at 7:00 am

It is self-evident that large systems of any type would not be possible without hierarchical design. Decomposing a large system objective into subsystems, and subsystems of subsystems, has multiple benefits. Smaller subsystems can be more easily understood and better tested when built, robust 3[SUP]rd[/SUP] party alternatives… Read More


Webinar: How RTL Design Restructuring Helps Meet PPA

Webinar: How RTL Design Restructuring Helps Meet PPA
by Bernard Murphy on 06-07-2017 at 7:00 am

To paraphrase an Austen line, it is a truth universally acknowledged that implementation, power intent and design hierarchy don’t always align very well. Hierarchy is an artifact of legacy structure, reuse and division of labor, perhaps well-structured piecewise for other designs but not necessarily so for the design you now… Read More
