Re: The problem of component editor

hello!

I meet a trouble when I learn how to edit a new component.I add a new component "pwm_motor" to the SOPC builder,but the output port pwm_out's signal type should be export.but it isn't in there.there are only

"address","begintransfer","begintransfer_n","beginbursttransfer"

,"beginbursttransfer_n","burstcount","byteenable","byteenable_n","chipselcet"

,"chipselect_n"."dataavailable";"dataavailable_n","endofpacket","endofpacket_n"

,"read","read_n","readdata","readdatavalid","readdatavalid_n","readyfordata",

"readyfordata_n","resetrequest","resetrequest_n","waitrequest","waitrequest_n",

"write","write_n","writebyteenable","writebyteenable_n","writedata".

which one should I select?

Hello,

The signals you quoted are for an Avalon Memory Mapped Slave. In the component editor, under the "interfaces" tab, add click on "Add Interface", and for this interface select the type "Conduit".

Now in the "Signals" tab, you add a signal, on column "Interface" select the conduit, and now in signal type you will find "export".

Hello,

I don't understant really what you expect. Join, I put an example of a component with a clock input interface, an avalon MM slave, and a conduit. There are the interface tab and the signals tab.

If you want details about the interface and signals, cf the avalon interface specification which explain the role of each one (http://www.altera.com/literature/manual/mnl_avalon_spec.pdf) (http://www.altera.com/literature/manual/mnl_avalon_spec.pdf%29).
