NVIDIA’s VP and GM of Autonomous Machines Deepu Talla kicks off keynotes at 2019 Robotics Summit
The 2019 Robotics Summit in Boston on June 5th and 6th is a premier robotics event focused on the design, development, manufacture, and delivery of commercial robotics. The Summit is co-located with the DeviceTalks event at the Seaport World Trade Center. Critical technical challenges remain when designing electronics for robotics systems particularly in the context of […]
Mistakes to avoid when submitting a design for PCB assembly
Simple prototype Printed Circuit Boards (PCBs) require, on average, 11.6 physical prototypes, whereas more complex PCBs require as many as 16.[i] And according to Advanced Assembly, a prototype PCB assembly house, “94% of assembly data is accidentally submitted with errors.”[ii] PCB assembly houses will extract design data from PCB design files and create a PDF […]
Quad port expander simplifies PCB layout for high-speed interfaces
Diodes Incorporated announced the introduction of the PI7C1401 quad port expander. The PI7C1401 is a cost-effective solution to low-speed signal management and I2C aggregation in advanced embedded systems using multiple high-speed interfaces. The PI7C1401 is suitable for any application that features multiple high-speed transceivers, including standard SFP (small form-factor pluggable), dual SFP (DSFP) and quad […]
Retargeting existing tests in an integrated SoC verification flow
by Matthew Ballance, Mentor, a Siemens Business The raison d’etre for portable stimulus is reuse. The Accellera Portable Stimulus Standard (PSS) promotes test intent reuse throughout the verification process and across the multiple engines on which those verification runs are performed. Test intent captured as portable stimulus models enables test reuse from the IP to […]
Understanding single-ended and differential communication systems
Do you know the difference between single-ended and differential communication schemes? And when should you use them, which one you should use, and why? Single-ended communications set ups are meant to be used only for short runs or to provide communication between devices on the same Printed Circuit Board (PCB). Single-ended communications will reference the […]
Choosing PCB materials to optimize applications, Part I
There are many different materials and methods for creating PCB materials. The electronics used in numerous applications benefits from the large number of options for PCBs. Hobbyists often choose the least expensive PCB, however, it’s essential to choose appropriate PCB materials when prototyping is done, and high-volume product development and manufacturing become the focus. Applications […]
Why clean PCBs matter, Part 1
Printed circuit boards (PCBs) are essential in modern electronics. Dust and other contaminants are more important to watch out for than ever. As components get smaller, the relative size of contaminants is larger, heat is more of an issue with densely packed circuits on modern ICs, and devices operating at high frequencies (~1 GHz and […]
