IBIS-AMI eCADSTAR | IBIS-AMI | Quadra Solutions



IBIS-AMI (AMI stands for Algorithmic Model Interface) models allow you to adjust buffer parameters (pre-/de-emphasis, equalization, and more) to optimize I/O channels for maximum performance.

  • Analyze SERDES channels (e.g. PCIe Express Gen3+, HDMI, SATA, USB, etc.) based on IBIS-AMI models.
  • S-Parameter characterization of the channel.
  • Eye diagram results, BER estimation, and bath-tub curves.
  • Import and manage IBIS-AMI devices in the simulation library.


  • A traditional IBIS model is an electrical description of buffer driving and receiving characteristics, excluding any programmable behavior like that present in SERDES transceivers. These include PCI Express, USB, SATA, as well as emerging memory standards such as DDR5.
  • eCADSTAR IBIS-AMI support addresses SERDES analysis needs (e.g. bit error rate, BER).
  • It’s channel analysis for Linear Time-Invariant Systems (LTI).
  • A SERDES analysis can take serious simulation time (many bits, minutes to hours).
  • The result will be an eye diagram (you may add an Eye mask for compliance checks if desired) and a bathtub curve to check BER compliance.
