Synopsys earned the first ever certification of a USB 3.1 Host IP Solution.
Last week I blogged about how USB Type-C would replace the 3.5mm audio jack in the future. I asked the readers to comment on what they thought about this. Below is one of the comments I didn’t approve
During IDF 2016 there was a lot of buzz around USB Type-C. Two of the hot topics were USB Type-C for audio and the announcement by the USB-IF to offer certification for Type-C chargers. Also, Synopsys demonstrated our USB-IF Certified 3.1 Gen 2 (10 Gb/s) host and device solution. Below is a picture of a video shoot from the show, we will publish the videos we shot in a couple of weeks.

Relationships Between USB Specs, Part Two & Where to Learn more about Type-C and DisplayPort alt mode
Recently I blogged on the relationships between USB Type-C, USB 3.1, Power Delivery and DisplayPort specifications. In my last blog I simplified the view focusing on the important and latest specifications. I think the simplified view answer most designer’s questions but there are still a few that like to see the full history and complex interactions. The below image, click to enlarge, provides a more detailed view of the different specifications, timeline representation and relationships.

I ran into this article online last week, http://www.laptopmag.com/articles/how-to-find-safe-usb-type-c-cables it discusses how a bad USB Type-C cable fried a Google engineers equipment, including a Chromebook Pixel. It also covers another issue when another bad Type-C cable drew too much power from a laptops port killing them. I highly suggest you read the article, but if you don’t have time then in summary; when a low quality, uncertified USB Type-C cable was used the incorrect resistance value for Type-C configuration causes the device to think it’s connected to a 3amp USB Type-C connection. Drawing 3A from a 500mA or 900mA port is not a good idea; the extra current draw damaged both devices. This issues reared its ugly head when using a USB Type-C to USB Type-A uncertified cable.
Synopsys worked with the USB-IF SSIC Working Group to develop a SSIC Proof of Concept demonstration.
