HFN: High Fanout Net, but I'm not familiar with encounter, maybe you should set the HFN to ideal net before CTS and cancle the set afer CTS. Hope it's helpful for you.
HFN is high fanout nets (like reset etc.). If you don't want to balance the skew, than no need to worry, Encounter can automatically take care of it.
But if you want to balance the skew. Simple option is to use the CTS algorithm, instead of specifying clock, specify the HFN net & encounter will build the buffer N/W to meet the specified skew requirement.

Could you elaborate on that? In Encounter, if I have a signal (output of a previous DFF register) which needs to fan out and to drive SE pins of many SDFF registers, how should I tell Encounter to meet skew requirement? Thank you very much!
