Abstract
A method includes modeling a design of a memory channel to provide a plurality of transfer functions associated with the design and multiplying an input spectrum with each of the transfer functions to provide a plurality of results. The method further includes summing the results to provide an output spectrum for the design, performing an inverse Fast Fourier Transform (FFT) on the output spectrum to provide an output signal for the design, and determining a bit error rate (BER) for the design based on the output signal.

An information handling system for simulating a memory channel, the information handling system comprising:
- a memory for storing code;
- and
- a processor operative to execute code to:
- model a design of a memory channel to provide a plurality of transfer functions associated with the design, wherein a particular one of the transfer functions models a memory configuration on the memory channel;
- perform a Fast Fourier Transform (FFT) on an input bitstream to the memory channel to provide an input spectrum;
- multiply the input spectrum with each of the transfer functions to provide a plurality of results;
- sum the results to provide an output spectrum for the design;
- perform an inverse FFT on the output spectrum to provide an output signal for the design;
- generate an eye diagram from the output signal;
- and
- determine a bit error rate (BER) for the design based on the eye diagram.
