Key new features include the ability to associate nets necessary for DDRx interconnect design. Multiple nets can now be “grouped” and given unique high-speed constraints, including length and differential pair rules. Associated nets adhere to these rules during [censored] and automatic routing, assuring that tight, high-speed performance specifications are met. Another feature allows a trace to “hug” an existing obstacle like another trace or board outline.
==== Some other softwares have supposed to have these features for years (more than 6 years) by the name of "net class", "trace hugging" etc etc. This needs to be checked ====
