请各位大侠帮我看一下这个ibis模型怎么了，这是我从TI官网上下载的，在编译的时候报错：
ERROR - Model Model67: The [Rising Waveform]
      with [R_fixture]=50 Ohms and [V_fixture]=0V
      has TYP column DC endpoints of  0.00V and  1.19v, but
      an equivalent load applied to the model's I-V tables yields
      different voltages ( 0.00V and  0.98V),
      a difference of  0.00% and 21.94%, respectively.

哪位大侠知道的帮帮忙啊，不知道的也帮我分析分析吧。
我这有一段解释：This happens because the function acdc_VI_Given_VIC_VR() in acdc.c improperly
reports the I-V/V-t intersection whenever it lies above the highest voltage in
the I-V characteristic.  This defect is likely to show itself in models lacking
clamp tables and in which either the [Pullup] or [Pulldown] table does not cover
the range from -Vcc to 2*Vcc.  Any open drain or open source model which lacks
clamp tables is likely to meet these conditions because it is likely to lack
either the [Pullup] or [Pulldown] table.  In this test case, IBISCHK generates
error messages only for the MIN data because the highest voltage in the high-
state I-V characteristic for the minimum corner lies below the 1.8 V V-T
operating voltage.

但是缺少该怎么做啊

学习了，非常感谢

grandwave

可能是VI曲线不单调,那Visual IBIS软件看下IBIS模型的VI数据，

我也想知道，大侠们赶紧来帮着解决一下啊。。。
