WARNING:Xst:2677 - Node <rand_temp_0> of sequential type is unconnected in block <filter_k>.
warning is stupid or you are telling about yourself?
Perhaps you should read the text of the warning. Then think about it, e.g. what means 'unconnected'. Then look into your design and repair it.

Did you read the 5 year old thread befor posting your question? The problem is somewhere in your code. Just have a look for the signal in question... BTW: I will not open any *.docx file of an unknown source. Simply attach a text file with the messages or copy them straight to the edit box.
if you intentionally want to leave an output port unconnected, you can indicate this to the tools with the keyword "open" in the port map.
