How to connect 16550 UART to Avalon interface when adding component to SOPC builder

[Altera_Forum]

Hi  

 I am trying to add the 16550 UART from opencores.org which uses a wishbone interface http://www.opencores.com/projects.cgi/web/uart16550/overview to SOPC builder, but I am not sure how to attach some of the signals to the Avalon interface. Does anybody know how to add the following signals:  - STB_I : input signal to the UART (Specifies transfer cycle) - CYC_I : input signal to the UART (A bus cycle is in progress) - ACK_O : output signal from the UART (Acknowledge of a transfer)  The () is the description of the signals from the documentation.  Have anybody tried to add this component to SOPC builder or know how to add these signals? If somebody has the *_hw.tcl file for the component and I could have a copy of it it would be even better.  My email is teilersen@hotmail.com  Thanks  Best regards  Tom
