Method and system for evaluating a device during circuit simulation

Abstract

A method for evaluating a device during circuit simulation includes receiving a first request including a first input value; and mapping the first input value to a first space in a table. The table is configured to store one or more table entries. A table entry includes an input value and a stored value. The stored value is obtained as a function of the input value from an analytical device model used to characterize the device during circuit simulation. The method includes determining whether the first space in the table is occupied by a first table entry; selecting a second table entry and a third table entry from the table when the first space in the table is not occupied by the first table entry, wherein the second table entry and the third table entry are neighbors in relation to the first space in the table; determining whether an accuracy criteria for performing a linear interpolation is satisfied as a function of the first input value, a stored value for the second table entry, and a stored value for the third table entry; and obtaining a first response value by performing the linear interpolation of the stored value for the second table entry and the stored value for the third table entry when the accuracy criteria is satisfied; and sending a response to the first request including the first response value. The first response value corresponds with the performance of the device when the device is configured using the first input value.
