High speed serial link specification
Detailed description of the link specification and parameters when paralleling HIL devices
The HIL paralleling feature is supported by HIL404, HIL602+, HIL604, and HIL606 devices.
Physical layer
HIL device models use different physical interfaces, as follows:
- HIL602+ and HIL604 - PCIe x4
- HIL404 - SFP
- HIL606 - QSFP
Link layer
The high speed serial link uses Xilinx Aurora link-layer protocol.
Parameter | HIL404 | HIL602+ | HIL604 | HIL606 |
---|---|---|---|---|
Operating frequency | 5 GHz | 5 GHz | 5 GHz | 16 GHz |
Number of lanes | 1 | 8 | 8 | 4 |
Maximum data rate – device to device | 125 variables/μs | 1000 variables/μs | 1000 variables/μs | 1000 variables/μs |
Maximum data rate refers to the maximum number of electric and signal processing variables which can be transferred in one microsecond.
