FilSynth provides the instant circuit diagram view for the obtained filter design during the synthesis, optimization or analysis process. All the design parameters are displayed in the circuit diagram instantly. 

For bandpass filter, the layout of the filter can be automatically arranged or adjusted manually to ensure the selected filter topology can be physically realized. Color of the coupling line are changed automatically to provide the status and worning to the designer. 

For bandstop filter, lowpass and highpass filter, the structures of the filters are relatively fixed so that the circuit is updated automatically by program.
