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：

- y- O% S$ l3 O/ e- Y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
7 Z/ s) y& m8 y" Vreports 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
& M4 a2 d5 y  _& o  b/ H% ?either the [Pullup] or [Pulldown] table.  In this test case, IBISCHK generates
' z1 @) l9 ~: `) t, A& r+ ?% ^3 yerror 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
