嗨ayusman，
我和你一样有同样的问题。
我使用一个简单的测试平台来模拟ASRC核心：
mclk：200 MHz
clkin：96KHz
clkout：48KHz
manual_ratio_en ='0'
manual_ratio =全0
imput_sample_a和imput_sample_b是随机值，随着时间的推移会随之改变。
我模拟了1秒，并在所有输出端口始终看到“UUUUUUU”。
我查看了ASRC核心的源代码。
对我来说，问题似乎是在重置期间没有启动许多信号。
当所有输入信号开始运行时，ASRC无法自动启动。
用户应该根据不同的要求进行初始化吗？
你能告诉我你是如何解决这个问题的吗？

Hi ayusman,
 
I have the same problem like you. I use a simple testbench to simulate the ASRC core:
 
mclk:    200 MHz
clkin:     96KHz
clkout:   48KHz
manual_ratio_en = '0'
manual_ratio = all 0
 
imput_sample_a and imput_sample_b are random values, which change themselves as time goes.
 
I have simulated 1 sec and see always "UUUUUUU" at all output ports.
 
I have looked into the source codes of the ASRC core. To me the problem seems like that many signals are not initiated during reset. And the ASRC can not start itself automatically when all the input signals begin to run. Should a user initialize them according to different requirements?
 
Can you tell me how you solved the problem?
 

这是波形
