Silvaco 仿真FET输出特性曲线IdVd 报错

Silvaco 仿真JFET，器件结构建立好后运行输出特性曲线仿真，报错如图： *Invalid parameter specification* 请问是哪里有问题？device 电极gate/drain/source 皆有定义，且转移特性曲线IdVg 仿真一切正常 .# Output characteristics_IdVd go atlas mesh infile=JFET.str # model models mos print # contact contact  name=gate workf=4.5 # method method newton gummel itlimit=25 trap atrap=0.5 maxtrap=4 autonr nrcriterion=0.1 tol.time=5e-3 dt.min=1e-25 damped delta=0.5 damploop=10 dfactor=10.0 iccg lu1cri=3e3 lu2cri=3e2 maxinner=25 # IdVd curve solve init solve vgate=-90 vsource=0 log outf=JOut_90.log solve name=drain vdrian=5 vstep=-1 vfinal=0 tonyplot JOut_90.log
