Response simulation from the frequency domain and time domain of digital signals.

Response waveform analysis of digital patterns using S-NAP/Field and Pro.

By analyzing multilayer substrates using S･NAP-Field, it is possible to analyze not only microwave circuits but also the coupling of digital circuits. To obtain response waveforms, waveform analysis can be performed using S･NAP-Pro based on the S-parameters obtained from S･NAP-Field, allowing for the observation of crosstalk and response waveforms at the waveform level. There are two methods for performing waveform analysis with S･NAP-Pro: one uses either the linear response waveform analysis function or the harmonic balance analysis function, and the other employs the convolution integral method to determine transient responses. Each of these methods has its own characteristics and should be chosen according to the specific objectives. This paper summarizes the overview and points of consideration for these methods. 【Methods】 ○ Extract signal sources present in the circuit ○ Perform Fourier transform on the signal sources, store the values of each spectrum, and create a frequency table ○ Execute AC analysis according to the frequency table created in the previous step, and obtain the spectrum at the observation point ○ Reconstruct waveforms at each observation point based on the spectrum For more details, please contact us or download the catalog.
