High-Speed Serial Interface (HSSI)
Simulation Objectives
PCIE5, SATA, SAS, SFP28, 10GBase-KR, 100GBase-KR, 56G/112G PAM4 and other high-speed serial signals
Simulation Difficulties
Impedance mismatch,excessive loss, serious ISI
Simulation Process
Cascade Design
Plan the lamination according to the actual situation, comprehensively consider the model, thickness, glue content, glue flow rate, etc. of the semi-cured sheet/core board, and provide reasonable impedance control, wiring layer/power ground plane planning and other suggestions.
Plate Selection
According to the system signal type and channel conditions, select the plate reasonably to ensure the signal quality and reduce the production cost.
Passive Channel Evaluation Based on S Parameter
Determine whether the channel conforms to the protocol standard through the S parameter, and analyze the details of the channel to ensure the system performance.
Active Simulation Based on HSPICE/AMI Model
Add a specific rate code type for eye graph simulation
Measured by eye height and eye width
