软件中的问题你注意到了吗？

典型的100ohm LVDS差分传输线，Hyperlynx场解析器的概念性错误
Field Solver Result：
Differential Z   = 100.5 ohms
   (suggested single line-to-line resistor for differential signals;
    works best for opposed, balanced transitions)
Common-mode Z    = 83.5 ohms（错在这里，这里求得的值是Even-mode Z，而非Common-mode Z）
   (suggested single line-to-ground resistor for common-mode signals;
    works best for all-1's or all-0's transitions)
Line-to-ground Z = 66.9 ohms
   (suggested single line-to-ground resistor for independent signals;
    works best for mixed 1's and 0's transitions)
