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：

1 n4 L6 A  p, s$ v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
, j/ l) f% t& x4 n- rthe 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
5 U6 O! ~, l# q# xthe 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
8 c* @( n/ E6 M( L8 \. T7 B) r! H0 Eerror messages only for the MIN data because the highest voltage in the high-

但是缺少该怎么做啊
