Zhangkun, do you want to only see the capacitance as a load with a presumed
receiver threshold, or do you want to approximate the transfer function
through the receive buffer?
If you just want to find the capacitance of the input, TDR the driving
trace. Unless the trace is very long, the capacitance should be
measureable from that test.
