Hi, Luis_Altera,

I am having the same problem with you. Could you please tell me more specifically on where to check the "generate a clk_ena pin"? I am using Quartus II 9.0 sp2.

Hello,

I am using Quartus II 9.0 too.I have got my data,but the source_valid is always low.I don't know how to find the "Global Clock Enable".I saw the word "Step 1: Parametrize" -> "Implementation Options",but can you tell me where is the "Parametrize"? And if you can tell me what cause the source_error,it will be better . My english isn't good but I hope you can understand my mean . my box :hanyang-sheep@163.com. I hope to receive you message.Please send mail to my box:hanyang-sheep@163.com .
