R，
流程变化使事情变得不同。
驱动电流是保证的最小值。
它可能远远超过上拉和下拉（并且它们永远不会完全相等，一个可能比另一个强40％）。
使用IBIS建模工具（如Mentor的Hyperlinx或其他CAD SI工具）执行信号完整性分析。
甚至可以使用spice（一些spice版本支持IBIS模型）。

r,
Process variations make things different. The drive current is the guaranteed minimum. It is likely much more than that for pull up, and pull down (and they are never exactly equal, and one could be 40% stronger than the other).
Perform a signal integrity analysis with an IBIS modeling tool, like Mentor's Hyperlinx, or another CAD SI tool. One may even use spice (some spice versions support IBIS models).
