Hi,

How can I make the AXI\_STREAM Monitor respond immediatly when a tvalid is seen?  
Meaning, assert tready when tvalid goes high?  
I can’t find anything on this in documentation.

The default is apparently to wait for a certain clocks, and I want to chang this behaviour.

Rgds,  
Eric

Another question, related to this is if you can drive Ready already high without waiting on tvalid?  
And if so, how?

Hi,

You can set the default value of the ready signal with the **ready\_default\_value** config. If you set the default value to ‘1’, then the behavior should be the same as if tready is set high on the same clock cycle as tvalid is set high.
