USB 3.0 Compliance Kit

Open Live Script

Characterize and validate the performance of a USB 3.0 channel design.

This kit is designed for analysis of a channel design between the USB 3.0 host and a USB hub, or between a USB 3.0 hub and a USB 3.0 device. The channel consists of a host board and a device board (hub or peripheral device) connected by a USB cable with two mated connectors consistent with the USB 3.0 specification.

This kit enables you to insert a channel design and characterize and validate its performance using the specification masks to determine if the channel has a high confidence of success. If the channel does not meet the compliance masks or BER estimates, further investigation or redesign, along with simulation, will need to be performed to determine possible changes to meet compliance.

Open USB 3.0 Kit

Open the USB 3.0 kit in the Serial Link Designer app using the openSignalIntegrityKit function.

Kit Overview

  • Project Name: USB_3p0

  • Interface Name: USB_3p0

  • Operating Frequency: 5 GB/s (UI = 200 ps)

The USB 3.0 kit defines three schematic sets. One schematic set focuses on channel compliance and one schematic set is for device compliance. Both long and short channels are modeled along with FEXT/NEXT aggressor characteristics for crosstalk simulations.

  • Channel_Compliance – Schematic sheets focused on channel end-to-end compliance. Serdes and widebus sheets

  • Device Compliance – Schematic sheets for DUT compliance driving either device or host boards. Widebus sheets only.

  • All_Schematics – All project schematic sheets

For more information about the USB 3.0 channel compliance schematics, transfer net properties, and compliance rules, refer to the document USB_3p0.pdf that is attached to this example as a supporting file.
