Probing UPF Dynamic Objects

UPF was created to go beyond what HDL can do for managing on-chip power. HDLs are agnostic when it comes to dealing with supply & ground connections, power domains, level shifters, retention and other power management related elements of SoCs. UPF fills the breach allowing designers to specify in detail what parts of the design… Read More


Does IDE Stand for Integrated Design Environment?

Does IDE Stand for Integrated Design Environment?

SemiWiki2 design 1

As regular readers may know, every few months I check in with Cristian Amitroaie, CEO of AMIQ EDA, to see what’s new with the company and their products. In our posts so far this year we’ve focused on verification, and now I’m wondering how an integrated development environment (IDE) provides benefits to designers. They work on huge… Read More


Low Power and RISC-V Talks at DAC2020, Hosted by Mentor

low battery

I’m going to get to low power and RISC-V, but first I’m trying out virtual DAC this year. Seems to be working smoothly, aside from some glitches in registration. But maybe that’s just me – I switched email addresses in the middle of the process. Some sessions are live, many pre-recorded, not quite the same interactive experience… Read More


The Moving Target Known as UPF

The Moving Target Known as UPF

UPF hierarchy

As if engineers did not have enough difficulty just getting everything right so that their designs are implemented functionally correct, the demands of lowering power consumption require changes that can affect functionality and verification. Techniques such as power gating, clock gating, mixed supply voltage, voltage … Read More


Synopsys Low Power Workshop Offers Breadth and Depth

Synopsys Low Power Workshop Offers Breadth and Depth
by Bernard Murphy on 06-18-2019 at 5:00 am

Synopsys seems to particularly excel at these events, whether in half-day tutorials at conferences or, as in this case, in a full-day on-site workshop. You might think there’s not much that can be added in this domain, other than to bring low-power newbies up to speed, but you’d be wrong. This event set the stage with surveys on needs… Read More


Magillem offers a practical UPF power flow

Magillem offers a practical UPF power flow
by Tom Simon on 05-28-2019 at 10:00 am

We already know that IP-Xact is extremely useful for managing IP and SOC design specifications, yet it may come as a surprise to learn that it also can be used to form the basis of a power flow too. There are design tools that read UPF to help implement and verify designs, however it can be extremely useful to understand the interplay … Read More


Foundational Excellence in a Laid-Back Style

Foundational Excellence in a Laid-Back Style
by Bernard Murphy on 04-24-2019 at 7:00 am

I recently had a call with Rob Dekker, Founder and CTO of Verific. If you’re in EDA or semiconductor CAD, chances are high that you know who they are. They’re king of the hill in parser software for SystemVerilog and VHDL. When you hear a line like that, you assume a heavy dose of marketing spin, but here it really is fact. I don’t know of… Read More


CEO Interview: Cristian Amitroaie of AMIQ EDA

CEO Interview: Cristian Amitroaie of AMIQ EDA
by Bernard Murphy on 07-05-2018 at 7:00 am

AMIQ EDA has caught my attention over the last few months. My first impression was that this was just another small IDE company trying to compete with established and bundled IDEs from the big 3, a seemingly insurmountable barrier. This view was challenged by an impressive list of testimonials, not just from the little guys but also… Read More


Low Power Verification Shifting Left

Low Power Verification Shifting Left
by Bernard Murphy on 05-08-2018 at 11:00 pm

I normally think of shift left as a way to move functional verification earlier in design, to compress the overall design cycle. But it can also make sense in other contexts, one particularly important example being power intent verification.

If you know anything about power intent, you know that it affects pretty much all aspects… Read More


Getting Low Power Design Right in Mixed Signal Designs

Getting Low Power Design Right in Mixed Signal Designs
by Bernard Murphy on 05-12-2016 at 4:00 pm

Mixed-signal design creates all sorts of interesting problems for implementation and verification flows, particularly when it comes to design for low power. We tend to think of mixed-signal as a few blocks like PLLs, ADCs and PHYs on the periphery of the design. Constrain and verify the digital power requirements up to analog … Read More
