SIDesigner Signal integrity simulation can help optimize the signal path of the memory interface. The Simulation can simulate the propagation process of the signal in the memory interface, import the real S-parameters and IBIS model, and then identify the paths with excessive signal delays and analyze the reasons for the delays, such as excessively long traces, impedance mismatch in the signal path, etc. The simulation can also simulate signal reflection between different impedance media, identify paths with excessive reflections, and analyze the causes of these reflections, such as impedance mismatches or corners in the signal path. Additionally, the simulation can model noise interference on the signal path, identify paths with excessive noise, and analyze the sources of this noise, such as power supply noise or electromagnetic interference.

After simulating the signal paths of existing solutions, simulation can help engineers adjust the length of the trace to reduce signal delays and reflections; it can also optimize the shape of the cable, such as the use of microstrip lines, ribbon lines, etc., to reduce signal delays and reflections. In addition, simulation can also help engineers optimize the power system to reduce power supply noise and interference.
