Scalability – A Looming Problem in Safety Analysis

Scalability – A Looming Problem in Safety Analysis

Scalability – A Looming Problem in Safety Analysis

The boundless possibilities of automation in cars and other vehicles have captivated designers to the point that electronic content is now a stronger driver of differentiation than any other factor. It accounts for a substantial fraction of material cost in any of these vehicles.… Read More


Scaling Safety Analysis. Reusability for FMEDA

Scaling Safety Analysis. Reusability for FMEDA
by Bernard Murphy on 06-23-2022 at 6:00 am

FMEDA generation

It is common when a new type of analysis is introduced in almost any domain that it works well enough for a while. Until it begins to struggle with growing problem size, prompting refinements to the methodology to allow continued scaling. We see this routinely in analytics for SoC design, so it should not be a big surprise that safety… Read More


Why Traceability Now? Blame Custom SoC Demand

Why Traceability Now? Blame Custom SoC Demand
by Bernard Murphy on 05-18-2022 at 6:00 am

Traceability abstract min

In the SoC world, we can’t believe our good luck. Every product maker now wants bespoke silicon solutions with the most advanced AI, communications, SLAM, etc. Which is fantastic for business, but this level of demand also drags us into a new level of accountability, especially in requirements traceability. Time was that only … Read More


Assembly Automation. Repair or Replace?

Assembly Automation. Repair or Replace?

Arteris SoC Integration 8000x4500 20210421 1

It is difficult to imagine an SoC development team not using some form of automation to assemble their SoCs; the sheer complexity of the assembly task for modern designs is already far beyond hand-crafted top-level RTLs. An increasing number of groups have already opted for solutions based on the IP-XACT integration standard.… Read More

Experimenting for Better Floorplans

Repartitioning min

There is sometimes an irony in switching to a better solution in design construction or analysis. The new approach is so much better that you want to experiment to further optimize the design. Which then exposes another barrier to enjoying that newfound freedom. SoC design teams often find this when switching from crossbar interconnect… Read More


An Ah-Ha Moment for Testbench Assembly

An Ah-Ha Moment for Testbench Assembly

Forest Trees min

Sometimes we miss the forest for the trees, and I’m as guilty as anyone else. When we think testbenches, we rightly turn to UVM because that’s the agreed standard, and everyone has been investing their energy in learning UVM. UVM is fine, so why do we need to talk about anything different? That’s the forest and trees thing. We don’t … Read More


Business Considerations in Traceability

Business Considerations in Traceability
by Bernard Murphy on 01-25-2022 at 6:00 am

nuclear power control room min

Traceability as an emerging debate around hardware is gaining a lot of traction. As a reminder, traceability is the need to support a disciplined ability to trace from initial OEM requirements down through the value chain to implementation support and confirmed verification in software and hardware. Demand for traceability… Read More


Traceability and ISO 26262

Traceability and ISO 26262

V graphic 2 min

Since traceability and its relationship to ISO 26262 may be an unfamiliar topic for many of my readers, I thought it might be useful to spend some time on why this area is important. What is the motivation behind a need for traceability in support of automotive systems development? The classic verification and validation V-diagram… Read More


Physically Aware SoC Assembly

Physically Aware SoC Assembly
by Bernard Murphy on 10-26-2021 at 6:00 am

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

Galileo min

Science texts like to present the evolution of knowledge as step-function transitions, from ignorance to wisdom. We used to think the sun revolved around the earth. Then Galileo appeared, and we instantly realized that the earth revolves around the sun. But reality is always messier, as Galileo understood all too well. The transition… Read More
