请问各位大侠个ccs lib的问题。
在ccs lib中，为了仿真计算delay值，建模为driver model ,reduced-order network model 和receiver model。
在receiver model中，分为pin-based receiver model和arc-based receiver model,请问这两个model的区别，
什么样的是pin-based receiver model，什么样的是arc-based receiver model？

谢谢！

查solvnet， library compiler的文档吧，  太细了

   谢谢版主，我查过资料和solvnet,还是不太理解怎么区分，好像是基本cells（buf,inv等等）的pins都是arc-based model,而像FFs的D pin就是pin-based model。但是还是对这两个概念模糊不清。
望指教！！！

哥，崇拜你啊，我从来都是把ccs直接拿来用，压根就没有去看这些库怎么算出来的，留个qq一起讨论哈

Arc-based is timing based, there is miller effect from the related output pin cap.
Pin-based means that the receiver pin has little dependency on the related output pin cap with its corresponding driver model.
