ADS的layout进行EM仿真，警告

Yonion

在ADS的layout进行EM仿真，出现以下两个警告。

WAENING1：
Accuracy can be lost due to matrix compression,you can rerun the simulation with reduced compression level or with the direct dense solver to verify the results.

WARNING2:
S-parameter data show unphysical behavior for certain frequences.
Cause: - electrically large port size
           - electrically large via using lumped model
           - mesh density is too coarse
           - matrix solver compression is too high
           - inaccurate (high frequency) calibration
警告一：按照提示reduced compression level之后，依旧有该警告；
警告二：S参数仿真结果不准确，不知道如何解决。
