How to use sys_reset_n, interface signal of Endpoint Block Plus core for PCIe

       

  

      

    

       

  

      

    

   

   

          

            

   

                

  

          

   

sys_reset_n is a top-level interface signal of Endpoint Block Plus core for PCIe . How to use it ?  When I design a PCI Express  Add-In card,should I connect sys_reset_n to PCI Express connector.

Hello,

 

Yes, for an add-in card, sys_reset_n should be connected to the Fundamental Reset that is provided on the PCIe slot, called "PERST#"

 

The core's User Guide (UG341) describes as follows:

 

"In a typical endpoint application, for example, an add-in card, a sideband reset signal is normally present and should be connected to sys_reset_n. For endpoint applications that do not have a sideband system reset signal, the initial hardware reset should be generated locally."
