Abstract

The production of semiconductor integrated circuits is very complex and expensive. Therefore, it is essential to verify the designed circuits before they are fabricated. Due to the process variations, nanoscale circuits have to be simulated many times during the design flow. This kind of analysis can be very expensive because of their complexity and the high number of simulations. For this reason the semiconductor industry is deeply interested in using less complex but accurate models to speed up time consuming SPICE simulations. This contribution presents a method that creates a compact model, which replaces a semiconductor integrated circuit or sub circuit to significantly reduce the transient simulation time.

Footnotes
1
This is used in the example presented in Sect. 4.
 
2
The computation of a transient output curve with 80 points in time needs about 4 ms. Fortunately this time just depends on the number of sample points and not on the complexity of the underlying circuit.
