请教hspice仿真attach的库与model file的mismatach问题

大家好,当我运行一个hspice文件,输出的log文件显示错误如下:
**error** no definition for 402:eval
it was called by 402pdist
**error** unknown function definition for eval
it was called by 402pdist
错误来源是attach的库中的:
opdist = 'eval(psdist>0?psdistmax(w,opndwmin) + 0.4e-6))'
error原因可能会是我attach的库中的tech file和model library不匹配造成的?或是PDK的什么问题?没有找到eval这个function.这个问题怎么改?如有知道的大侠们请不吝赐教,我在这里谢谢大家了.

怎么有一点乱码,重新整理一下:
**error** no definition for 402:eval
it was called by 402:opdist
**error** unknown function definition for eval
it was called by 402:opdist

the source of error is:
opdist = 'eval(psdist>0?psdist:(max(w,opndwmin) + 0.4e-6))'
