3.5. HVIO Simulation

Intel provides three types of simulation models for Agilex™ 5 devices.

These simulation models are:

  • Synopsys* HSPICE* models
  • IBIS models
Table 33.  Simulation Models Descriptions
Model Supported I/O Type Description
HSPICE* HVIO
  • Simulates actual transistor level design to obtain precise electrical simulation.
  • The syntax describes I/O buffers, board components and connections, and specific simulation parameters.
  • The model contains encrypted transistor and logic cell library models, output buffer circuit models for single-ended and differential I/Os, and sample SPICE decks for single-ended and differential I/Os.
  • The model requires a longer simulation time compared to the IBIS model.
IBIS HVIO
  • This is a behavioral model of the I/O buffers based on the I/V curve data derived from the HSPICE* simulation.
  • The pre-emphasis feature is an example that can use the IBIS simulation model.
  • This model has a shorter simulation time compared to HSPICE* .
  • The simulation model has less complexity compared to HSPICE* models and supported by many simulation tools.
