Artificially stalling datapaths and virtual channels is a creative method to uncover corner case timing bugs. A paper from Nvidia describes a refinement to this technique. Paul Cunningham (GM, Verification at Cadence), Raúl Camposano (Silicon Catalyst, entrepreneur, former Synopsys CTO and now Silvaco CTO) and I continue… Read More
Refined Fault Localization through Learning. Innovation in Verification
This is another look at refining the accuracy of fault localization. Once a bug has been detected, such techniques aim to pin down the most likely code locations for a root cause. Paul Cunningham (GM, Verification at Cadence), Raúl Camposano (Silicon Catalyst, entrepreneur, former Synopsys CTO and now Silvaco CTO) and I continue… Read More
224G Serial Links are Next
The tremendous increase in global data traffic over the past decade shows no sign of abating. Indeed, the applications for all facets of data communications are expanding, from 5G (and soon, 6G) wireless communications to metropolitan area networks serving autonomous vehicles to broader deployment of machine learning algorithms. … Read More
Tensilica Edge Advances at Linley
The Linley spring conference this year had a significant focus on AI at the edge, with all that implies. Low power/energy is a key consideration, though increasing performance demands for some applications are making this more challenging. David Bell (Product Marketing at Tensilica, Cadence) presented the Tensilica NNE110… Read More
ML-Based Coverage Refinement. Innovation in Verification
We’re always looking for ways to leverage machine-learning (ML) in coverage refinement. Here is an intriguing approach proposed by Google Research. Paul Cunningham (GM, Verification at Cadence), Raúl Camposano (Silicon Catalyst, entrepreneur, former Synopsys CTO and now Silvaco CTO) and I continue our series on research… Read More
Cadence and DesignCon – Workflows and SI/PI Analysis
DesignCon 2022 is back to a live conference, from Tuesday, April 5th through Thursday, April 7th, at the Santa Clara Convention Center.
Introduction
DesignCon is a unique gathering in our industry. Its roots incorporated a focus on complex design and analysis requirements of (long-reach) high-speed interfaces. Technical… Read More
Symbolic Trojan Detection. Innovation in Verification
We normally test only for correctness of the functionality we expect. How can we find functionality (e.g. Trojans) that we don’t expect? Paul Cunningham (GM, Verification at Cadence), Raúl Camposano (Silicon Catalyst, entrepreneur, former Synopsys CTO and now Silvaco CTO) and I continue our series on research ideas. As always,… Read More
Leveraging Virtual Platforms to Shift-Left Software Development and System Verification
Ever since the cost of development started growing exponentially, engineering teams have been deploying a shift-left strategy to software development and system verification. While this has helped contain cost and accelerated product development schedules, a shift-left strategy is not without challenges. A virtual platform… Read More
Using a GPU to Speed Up PCB Layout Editing
I can remember back in the 1980s how Apollo workstations were quite popular, because they accelerated the graphics display time for EDA tools much better than competitive hardware. Fast forward to 2022 and we have the same promise of speeding up EDA tools like PCB layout editing by using a GPU. At the 58th DAC there was a session called,… Read More
Dynamic Coherence Verification. Innovation in Verification
We know about formal methods for cache coherence state machines. What sorts of tests are possible using dynamic coherence verification? Paul Cunningham (GM, Verification at Cadence), Raúl Camposano (Silicon Catalyst, entrepreneur, former Synopsys CTO) and I continue our series on research ideas. As always, feedback welcome.… Read More
