| Transmission line simulations enable system operating verification at the design stage. As well as enabling prior verification of terminating resistor and circuit numbers previously carried out after component loading, simulations reduce system development requirements and costs by optimizing PWBs and package substrate design. |

| Once an ideal differential circuit is achieved, transmissions of more than 1Gbps can be achieved even with FR-4 boards. By employing a transmission line simulator, signals can be more reliably transmitted at much higher speeds. |
| Example of high-speed differential signal analysis |
|
| Verifying pre-emphasis effects and measuring waves through simulation (bit rate = 3.125 Gbps and ideal transmission circuits) |

| ■Pre-emphasis=0% |

| ■Pre-emphasis=124% |
