ADS 报错啊，求救

各位大大，使用ADS2008仿真微带滤波器，出现错误，帮我看看啊
Error detected by hpeesofsim during Nominal Optimization `Optim1'. OptimGoal/YieldSpec/DoeGoal did not find any relevant simulation points. Please check to insure any OptimGoal/YieldSpec/DoeGoal range contains at least one simulation point The OptimGoal/YieldSpec/DoeGoal device in question is: OptimGoal3  
我的设置

谢谢大家了菜鸟求助

[size=4]微带滤波器的指标为：通带频率5.96.1GHz,通带内波纹指数为0.1dB，阻带边频6 ± 0.3
GHz外衰减大于30dB

s21都应该是负的吧? Goal里的最大值改成-30dB
