METHOD FOR MODELING SIGNAL TRANSIENT CHARACTERISTIC OF MULTI-COUPLED FREQUENCY-VARIANT TRANSMISSION LINES

摘要

PURPOSE: A signal transition property modeling method of a cabling system with the frequency dependency property is provided to accurately decide the signal of computer integrity of multi-circuit by reflecting the high frequency effect to the switching pattern of an input signal, and the cross-talk of the signal according to the rising/fall time and the length. CONSTITUTION: N number of transmission line included in a frequency-dependency cabling system is converted to one of a RLC transmission line comprising n number of native mode. An answer signal waveform of each native mode is modeled(S110). A progressive system about each of the transmission line of n is expressed in the liner combination toward the native modes of n(S120). The answer signal about the transmission line of n is finally modeled corresponding to the specific switching pattern by assigning the answer signal waveform of the modeled native mode as described above for each of the progressive system(S130).
