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
- t! _( ^/ J4 Lreports 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

clamp tables is likely to meet these conditions because it is likely to lack
