Mesh Networks, Redux

Mesh Networks, Redux
by Bernard Murphy on 09-27-2018 at 7:00 am

It isn’t hard to understand the advantage of mesh networking (in wireless networks). Unlike star/tree configurations in which end-points connect to a nearby hub (such as phones connecting to a conventional wireless access point), in a mesh nodes can connect to nearest neighbors, which can connect to their nearest neighbors… Read More


Eclipsing IDEs

Eclipsing IDEs
by Bernard Murphy on 03-10-2017 at 7:00 am

In a discussion with Hilde Goosens at Sigasi, she reminded me of an important topic, relevant to the Sigasi Image Removedplatform. Some aspects of technology benefit from competition, others less obviously so and some absolutely require standardization. Imagine how chaotic mobile communication would be if wireless protocols… Read More


Software-Driven Verification Drives Tight Links between Emulation and Prototyping

Software-Driven Verification Drives Tight Links between Emulation and Prototyping
by Bernard Murphy on 04-28-2016 at 12:00 pm

I’ve mentioned many times what has become a very common theme in SoC and system verification Image Removed– it has to be driven by the software because any concept of exhaustively verifying “everything” is neither feasible nor meaningful. Emulation has become a critical component of this flow in validating… Read More


Verdi: there’s an App for that

Verdi: there’s an App for that
by Paul McLellan on 10-03-2011 at 5:58 am

Verdi is very widely used in verification groups, perhaps the industry’s most popular debug system. But users have not been able to access the Verdi environment to write their own scripts or applications. This means either that they are prevented from doing something that they want to do, or else the barrier for doing it is… Read More


Analog Constraint Standards

Analog Constraint Standards
by Paul McLellan on 09-20-2011 at 8:00 am

Image RemovedOver the years there has been a lot of standard creation in the IC design world to allow interoperability of tools from different vendors. One area of recent interest is interoperable constraints for custom IC design. Increasingly, analog design layout is becoming more automated. Advanced process nodes require… Read More


OpenAccess

OpenAccess
by Paul McLellan on 06-21-2011 at 1:11 pm

Image RemovedProbably everyone knows that openAccess is a layout database. It was originally developed at Cadence (called Genesis) but has since been transferred to Si2. Strictly speaking, openAccess is actually an API and the database is a reference implementation. The code is licensed under a sort of halfway to open-source:… Read More
