- A new SerDes simulation feature has now been added to Network Analysis for single or differential lines. This feature verifies the Bathtub and Statistical eye diagrams for the IBIS-AMI-based SerDes models in SI. A SerDes system simulation involves a transmitter (Tx) and a receiver (Rx) connected by a passive analog channel. You can perform statistical analysis and time-domain analysis. This function will enable you to quickly and accurately analyze the SerDes full channel composed of PCB, Connector, and Cable.

- A new feature to enable automatic setup of pin mapping using Excel has now been added to the package S-Parameter model in SI. After extracting the S-Parameter of the package using Network Analysis, you can perform Signal Integrity Analysis of the entire flow of DIE + Package + PCB more easily by connecting it to the simulation model. However, to extract the S-Parameter Model of the Lead Wire of the package, use other 3D tools.

- The IR Drop engine has now been enhanced to mesh 'trace-type net' which improves accuracy in PI. Since the mesh trace requires more analysis time, you can select the mesh type and review the Current Density in the trace-type object based on your requirements.
