说明： 通过 fpga 控制音频编解码芯片 wm8731 产生一个 1khz 的正弦波，接上 AC620
板上的耳机接口，试听此正弦波。（注意，声音比较大，如果为了保险，可以使用
带音量控制的音响，也可以用示波器观察）。
(The audio codec chip wm8731 is controlled by FPGA to produce a 1 kHz sinusoidal wave connected with AC620
Listen to this sinusoidal wave with the earphone interface on the board. (Note that the voice is louder. For insurance purposes, you can use it.
Audio with volume control can also be observed by an oscilloscope.)

This folder contains data for incremental compilation.
The compiled_partitions sub-folder contains previous compilation results for each partition.
As long as this folder is preserved, incremental compilation results from earlier compiles
can be re-used. To perform a clean compilation from source files for all partitions, both
the db and incremental_db folder should be removed.
The imported_partitions sub-folder contains the last imported QXP for each imported partition.
As long as this folder is preserved, imported partitions will be automatically re-imported
when the db or incremental_db/compiled_partitions folders are removed.
