| # Problems in v-t curve modeling and simulation
| IBIS 2.1 introduced v-t curves so simulation can be more accurate. The idea was elegant and the implied assumption was that as long as the simulator reproduced the "golden" input v-t data the modelling and simulation could be deemed accurate and consistent. However we will show that reproducing golden vt data is not a sufficient measure and does not guarantee correct modelling. Accurate modelling still requires technology and vendor dependent assumptions which are outside IBIS realm. More troublesome is that the correctness of these assumptions are not easily verified and undermine the users confidence. This situation can be easily corrected by including current waveforms in addition to the voltage forms. Algorithms that incorporate current waveforms are straightforward and results in simulations which are absolutely accurate. An important added benefit is verfiable modelling which is vendor and technology independent.
