hsim is mix-mode simulator some block

can use behavior description

hsim仿真memory不错，但是如果不做精度设置，在仿真analog circuit时精度会有问题，甚至可能出现功能上的错误。

还好两个软件有差别

hsim速度快，容量大，但精度低。
hspice速度慢，容量小，但精度高。

Hsim is from Nassda which was acquired by Synopsys 6~8 years ago.
Nassda was found by Chinese guy. After synopsys acquisition, the original founder of Nassda creates Spice-explorer which is a very popular and easy-to-use waveform viewer, then thsi company was acquired by Synopsys again.

Hsim can be used to simulate SDM audiocodec up to 100dB without any accuracy issue, this had been verified in real silicon measurement.

To reach the accuracy you want, the option selection/setting is key to trade-off speed/accuracy.
