Test vector generation for ethernet frame using VHDL

[rajalakshmisahoo]

Hi,

I need to know how do we go about generating a test vector for an
ethernet frame. We r using the CPCS core that generates the ethernet
data. but for our testing purpose i need to drive the output signal to
a GFP framer. So i wud like to know how to generate the ethernet frame.
Are there any existing codes for this purpose.

thanking u

Most cores come with some sort
of sample testbench.
Have a look at the data sheet.

but for our testing purpose i need to drive the output signal to
a GFP framer. So i wud like to know how to generate the ethernet frame.

Ethernet interfaces have a
high speed 4 or 8 bit TX, RX bus.
There is normally a MAC core also for
with a buffered processor interface.
You can capture sample frames using

Are there any existing codes for this purpose.

Check with the core supplier.
No one else would be likely have time
to provide free reference designs.
