We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

因为是100% 才停止仿真,说明仿真时间不够,再增加100倍试一下。可能是因为传播距离太长。你在传播的末端加一个时间监视器,看看信号是否彻底衰减。记住,仿真一般不能达到100%再停止,应该早停止。参见
