Path Based UPF Semantics

The development of the Unified Power Format (UPF) was spurred on by the need for explicit ways to enable specification and verification of power management aspects of SoC designs. The origins of UPF date back to its first release in 2007. Prior to that several vendors had their own methods of specifying power management aspects … Read More


MBIST Power Creates Lurking Danger for SOCs

MBIST Power Creates Lurking Danger for SOCs

MBIST power emulation

The old phrase that the cure is worse than the disease is apropos when discussing MBIST for large SOCs where running many MBIST tests in parallel can exceed power distribution network (PDN) capabilities. Memory Built-In Self-Test (MBIST) usually runs automatically during power on events. Due to the desire to speed up test and … Read More

SoC Assembly min 1

We used to be comfortable with the idea that the worlds of logical design and physical implementation could be largely separated. Toss the logical design over the wall, and the synthesis and P&R teams would take care of the rest. That idea took a bit of a hit when we realized that synthesis had to become physically aware. The synthesis… Read More

Electronic design automation (EDA) has come a long way from its beginnings. It has enabled chip engineers from specifying designs directly in layout format during the early days to today’s capture in RTL format. Every advance in EDA has made the task of designing a chip easier and increased the design team productivity, enabling… Read More


Netlist CDC. Why You Need it and How You do it.

Netlist CDC. Why You Need it and How You do it.

The most obvious question here is “why do I need netlist CDC?” A lot of what you’re looking for in CDC analysis is really complex behaviors, like handshakes between different clock domains, correct gray coding in synchronizing FIFOs, eliminating quasi-static signals and the like. Deeply functional, system-level intent stuff.… Read More

I attended a session on 2.5D silicon interposer analysis at DesignCon 2020. Like many presentations at this show, ecosystem collaboration was a focus. In this session, Jinsong Hu (principal application engineer at Cadence) and Yongsong He (senior staff engineer at Enflame Tech) presented approaches for interposer power modeling… Read More


Low Power SRAM Complier and Characterization Enable IoT Applications

Low Power SRAM Complier and Characterization Enable IoT Applications
by Tom Simon on 02-22-2019 at 7:00 am

If you are designing an SOC for an IoT application and looking to minimize power consumption, there are a lot of choices. However, more often than not, looking at reducing SRAM power is a good place to start. SRAMs can consume up to 70% of an IC’s power. SureCore, a leading memory IP supplier, offers highly optimized SRAM instances … Read More


The Cloud-Edge Debate Replays Inside the Car

The Cloud-Edge Debate Replays Inside the Car
by Bernard Murphy on 10-25-2018 at 7:00 am

I think we’re all familiar with the cloud/edge debate on where intelligence should sit. In the beginning the edge devices were going to be dumb nodes with just enough smarts to ship all their data to the cloud where the real magic would happen – recognizing objects, trends, need for repair, etc. Then we realized that wasn’t the best… Read More

The Robots are Coming!
by Bernard Murphy on 08-30-2018 at 7:00 am

Moshe Sheier, VP Marketing at CEVA, recently got back from MWC Shanghai and commented that robots are clearly trending. He saw hordes of robots from dozens of companies, begging for someone to brand and offer them in any one of many possible applications: in an airport to guide you to a connecting flight, for elder care, in hospitals… Read More


John Lee: Market Trends, Raising the Bar on Signoff

John Lee: Market Trends, Raising the Bar on Signoff
by Bernard Murphy on 06-07-2018 at 7:00 am

I talked to John Lee (GM of the ANSYS Semiconductor BU) recently about his views on market trends and the ANSYS big-picture theme for DAC 2018. He set the stage by saying he really liked Wally’s view on trends (see my blog on Wally’s keynote at U2U). John said these confirm what he is seeing – a trend to specialization, some around… Read More
