Complexity is making this process more difficult, but new and better approaches are being developed.

Semiconductor Engineering

 

The proliferation and expansion of multicore architectures is making debug much more difficult and time-consuming, which in turn is increasing demand for more comprehensive system-level tools and approaches.
Multicore/multiprocessor designs are the most complex devices to debug. More interactions and interdependencies between cores mean more things possibly can go wrong. In fact…

The role of engineers is changing, and they need to be picking up new skills if they are to remain valuable team players. There are several directions they could go in.

Engineering has one constant — you innovate or fall by the wayside. That is true both for the things that are designed and for the engineers who design and build them. Today’s systems are putting new strains on engineers who can no longer be “tall and thin” or “short and fat.” Those descriptions pertain to an engineer who is either highly…

Continuous design innovation adds to verification complexity, and pushes more companies to actually do it.

Semiconductor Engineering

 

The RISC-V ecosystem is struggling to keep pace with rapid innovation and customization, which is increasing the amount of verification work required for each design and spreading that work out across more engineers at more companies.

The historical assumption is that verification represents 60% to 80% or more of SoC project effort in terms of cost and time for a mature,…

Uses, challenges and tradeoffs in working with vector engines.

Semiconductor Engineering

 

A search is underway across the industry to find the best way to speed up machine learning applications, and optimizing hardware for vector instructions is gaining traction as a key element in that effort.
Vector instructions are a class of instructions that enable parallel processing of data sets. An entire array of integers or floating point numbers is processed in a single operation, eliminating the loop control…
