How to confirm clock generating correctly in each layer example like USB3.0 or Ethernet or PCIE

How to make sure clock generating correctly in usb3.0 Due to different clock for each layer?
Anyone have experince in USB3.0 Design Verification,please respond?

In reply to Subbi Reddy:
The specs should define the acceptable pulse widths and variations due to line losses.
You can use SVA to do such measurements. See

Which issues are you having trouble with. You need to be more specific.
