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：

我这有一段解释：This happens because the function acdc_VI_Given_VIC_VR() in acdc.c improperly

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

error messages only for the MIN data because the highest voltage in the high-

operating voltage.
