Comparison of IBIS model Vt table vs. Rise/Falltime
Rise/Fall Time
uses an average value of risetime/falltime to
set the time constant of a capacitor.
Usable back to IBIS v1.0
Uses SDD-based equivalent circuit
Can be used in HB as well as Transient
simulation
Vt Table
uses voltage lookup table (Vt)
Usable starting with IBIS v2.x
Uses FDD-based equivalent circuit
Can be used only in Transient simulation
