Why Asynchronous Reset in our Design ?

If we adopt an asynchronous reset, it can take effect immediately. But I do't think we have to use the asynchronous Reset。

Addionally，we spend more device resourses using synchronous reset, but make less mistakes.

Thanks @guguwuwu for the link. WP272 & WP275 are a must read.
 

It really depends on the device.
In Altera devices, all resets are asynchronous. Sync resets in the code are actually created by muxing the input to a D input. But Xilinx devices have a specific Sync reset on all registers.
