To USB or Not to USB


Industry’s First Demo of USB 3.0 SSIC and MIPI M-PHY Passing USB Compliance Tests

I’m proud to report Synopsys is the first and only company to demonstrate a real USB 3.0 Host and USB 3.0 Device working with a real MIPI M-PHY and not only demonstrating traffic, but demonstrating how we can pass the tests run by the standard USB Compliance Verifier (USBCV) 3.0.

Before we begin, remember that SSIC is USB 3.0 SuperSpeed InterChip.  It allows for the use of USB 3.0 inside the box, and on the circuit board.  Not external physical connectors.  All on PCB using FR4 traces of up to 10cm long.   SSIC uses a MIPI M-PHY so the power consumption is between 40-80% lower than a standard USB 3.0 PHY while still providing a throughput
The USBCV tests are used to test USB 3.0 Hosts and Peripherals for compliance.

In our setup, we use the HAPS51-2 with a MIPI M-PHY on a daughter card for both the USB 3.0 Host and Device implementations.  Each is connected to a standard PC.

Our USB 3.0 Host PC, we run Windows 7 with a MCCI USB 3.0 Host drive.

On our USB 3.0 Device, the PC uses a Linux driver.  The Device is, like all of our other demos, a USB Mass Storage Device. (Basically a giant USB flash drive)

The connection between the two systems is only 4 co-ax cables running from the M-PHY on one platform to the other platform.  Since SSIC is really for on PCB or for modules.

A future video will explain this setup in detail.

Watch the video below to understand more below.

As with our first, original demo back in April 2012, we use unmodified USB 3.0 Device Firmware and USB 3.0 Host drivers.

And for fun, go back to this blog and review the original demonstration of our USB 3.0 Host and Device SSIC Proof of Concept Demonstration back in April 2012.  This was the one we used to help the USB-IF clarify the specification

USB University

Remember to check out USB University.  It’s appropriate for managers and marketers working on or considering USB 3.0, and for architects and engineers that need deep technical detail.

I wanted to say this was the first demonstration of USB 3.0 SSIC with a MIPI M-PHY in the Universe, but I was overruled by a sense of conservatism.  (It probably is the first)

Here’s Hezi Saar, our MIPI M-PHY guy and I getting ready for our video shoot.

I’m not sure why he is smiling.  Check out his Blog OnTheMove for more on SSIC and MIPI.

Note that Hezi’s Gear 1, Gear 2 and Gear 3 M-PHY supports Gear 1, Gear 2, and Gear 3 speeds.

SSIC will be used in WiFi, LTE, WiGig / 60 GHz designs to connect to Mobile Applications Processors
