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：

0 q; H! h; I/ f1 d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
# o& m; ~2 Z, I/ m3 S5 s# jclamp 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

但是缺少该怎么做啊
