在进行spectre仿真，所引用的n50，p50mos管模型无法开始仿真，错误如附件，求大神帮助

Please check for you model.scs file, looks like a corner definition error.
Some model parameters are defined twice.

ERROR (SFE-1999): "/opt/SMIC_018_MMRF/models/spectre/ms018g_v1p16.mdl" 435: Model `n50': parameter `toxe': Cannot run the simulation because an unknown parameter `dtoxe_n50' has been specified in expression `1.252e-08+dtoxe_n50'. Correct the expression and rerun the simulation.

参数问题一般都是仿真工具版本不符合要求。看看手册对仿真器的要求。

this is p50 parameter*             general model parameters

**************************************************************

+xw    = '1.58e-008+dxw_p50' looks like  X=C+dX，could i understand like this？ or , can delete dxw_p50?  then the parameter become a number.will it have the same effect?
