Checking for OpenPOWER Compliance
SystemSI includes the frequency-domain compliance kit that OpenPOWER partners can use
to determine if their high-speed serial (HSS) bus designs are compliant with IBM standards.
The tool determines compliance based on seven Frequency Domain Parameters describing
the fully cascaded channel from C4 bump to C4 bump.
The compliance tool kit checks compliance of all HSS buses escaping from the IBM POWER8
processor. As the tool is frequency domain-based, no IBIS AMI models are needed for the
simulation to run. Ensure that you use accurate s-parameter models of the passive
components in the channel describing the worst-case design space.
This guide is for first-time users and will to help you run the simulation and interpret the
results. A step-by-step procedure for determining a PCIe Gen3 reference channel’s
compliance is covered as an example.
