To USB or Not to USB


Certified USB 3.0 Host IP from Synopsys

Synopsys, the only IP company with Certified Host & Device IP

Not only that, we had our PHYs in these systems also when we certified our Host and Device.

PHYs in multiple processes.  PHYs that run at all USB speeds.

I’d spend another 12 paragraphs telling you how having the complete USB IP “solution” really brings greater depth & breadth to our product/expertise/support, but you know all that.

Press Release here

Synopsys as the only SuperSpeed USB 3.0 Dual Role Device IP certified in both Device mode and Host mode. 

You didn’t know that.

So if you want the advantage of having a Dual Role Device that

a) Works it Host mode

b) Works in Device mode

c) Has been Certified in Host Mode and Device Mode

This Shameless Self Promotion is almost over.  It won’t last long because I save the best parts for when I actually talk to customers.


Synopsys earned SuperSpeed USB certification of our USB 3.0 xHCI Host controller. 

A simple statement that means a lot.

To receive certification you need to:

  1. Pass Gold Tree Interoperability tests that includes
  • 5 layers of USB hubs (USB 3.0 and USB 2.0)
  • Low Speed USB 1.1 Keyboards/Mice
  • Full Speed USB 1.1 Audio Speakers
  • Hi Speed USB 2.0 Hard Drives, Webcams, and Printers
  • SuperSpeed USB 3.0 Peripherals
  • Pass xHCI Testing – This takes weeks to run
  • Pass Electrical Testing – We’ve done this many times with our PHY
  • Interoperate with 250 USB 2.0 peripherals.
  • The 250 USB 2.0 peripherals take 10 days of testing at 12+ hours per day. (If you don’t actually have to debug anything.) You actually to run the device to make sure it works properly.

    For the consumer it answers the question: Will my existing “stuff” will work?

    The features that make USB easy to use, make it challenging for our customers to implement.

    Next Time: SSIC and MIPI – or SuperSpeed InterChip and why you should care. And the answer to the question.
