High speed serial link specification

Detailed description of the link specification and parameters when paralleling HIL devices

The HIL paralleling feature is supported by all HIL devices. Paralleling is possible across devices of the same model, as well as between HIL506 and HIL606 devices. The maximum number of devices in parallel is dependent on the link parameters.

Physical layer

HIL device models use different physical interfaces, as follows:

  • HIL602+ and HIL604 - PCIe x4
  • HIL101 and HIL404 - SFP+
  • HIL506 and HIL606 - QSFP28
