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
reports the I-V/V-t intersection whenever it lies above the highest voltage in
  B/ b( g+ L2 K( M- z- w! Athe I-V characteristic.  This defect is likely to show itself in models lacking
; `% h0 Y2 c6 E8 g2 Z1 D% Uclamp 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
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
0 o7 o$ j; `+ `2 gerror messages only for the MIN data because the highest voltage in the high-
( K1 f* h( R6 ^) j7 n& Astate I-V characteristic for the minimum corner lies below the 1.8 V V-T
