Component Editor problem

Hello,

I have a problem with the Component Editor:

I create following component with the Component Editor.

The following signals are used on the SIGNAL area.

NAME INTERFACE SIGNAL TYPE DIRECTION WIDTH

clk50 clock_in clk Input 1

address cbi_avalon_slave address Input 4

cs cbi_avalon_slave chipselect Input 1

read cbi_avalon_slave read Input 1

readdata cbi_avalon_slave readdata Output 16

write cbi_avalon_slave write Input 1

writedata cbi_avalon_slave writedata Input 16

On the bottom of the SIGNAL area I have the Info: “No errors or warnings”

On the INTERFACE area I have declares the “clock_in” and the “cbi_avalon_slave”.

On the button of the INTERFACE area I have the Info: “No errors or warnings”

If I push the button “Preview the GUI…” on the COMPONENT WIZARD area I get a Warning: in the Preview window “clock_in1: Interface has no signal”.

If I use this component on the SOPC Builder I get a Warning: in the info area on the bottom of the SOPC window “CBI1.clock_in1: Interface has no signal”.

Where is the error?

Thanks

Weibu
