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：

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

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
