IBIS-AMI MODELS AND SIMULATION DATASHEET

AMI analysis goes beyond traditional waveform simulation. AMI simulation is most valuable when transceivers include features that cannot be modeled by analog electrical descriptions alone.

eCADSTAR IBIS-AMI

Traditional IBIS models describe buffer driving and receiving characteristics but cannot model advanced features to compensate for interconnect loss like pre-emphasis and equalization techniques which are common in modern Serializer/Deserializer (SERDES) channels like PCI Express.
IBIS-AMI models include the capability to model this behavior, so you can adjust various parameters to optimize I/O channels for maximum performance.
As with other kinds of simulation, IBIS-AMI models become even more valuable when you push density and speed envelopes and ultra-high-speed SERDES circuits are closely packed with other parts of your designs.

TOP BENEFITS. WHY DO YOU NEED AMI SIMULATION?

  • IBIS-AMI models are needed to simulate advanced transceivers like those in PCI Express (PCIe). These transceivers use dedicated Digital Signal Processing (DSP) like techniques to condition signals for ultra-high bitrates.
  • Higher-level verification with long stimulus patterns is essential to find key channel performance parameters like Bit Error Rate (BER) which is defined by the underlying protocol.
  • IBIS-AMI models can be adjusted by various parameters to optimize I/O behaviour for maximum performance.
