Setting output delay

You have created a single data rate source synchronous interface, so you have to create a generated output clock as the reference clock. See this online training for the details:

Constraining Source Synchronous Interfaces

Yes, that looks good. Your max and min values should of course be based on the timing requirements of the "downstream" device that you are connecting to, and usually those values (or at least not both of them) aren't negative. Do you have setup/hold info or skew info for the downstream device?

#iwork4intel

Yup.

So I should first use the "create_generated_clock" command like this:

create_generated_clock -name clock_out -source [get_ports {clock_in}] [get_ports {clock_out}]

And then use the the generated clock as reference:

set_output_delay -clock clock_out -max -1.0 [get_ports data_out]
set_output_delay -clock clock_out -min -0.1 [get_ports data_out]

Correct ?

Thanks,

That was a theoretical question - so the actual setup/hold times aren't relevant.

Is there another lecture on DDR interfaces ?

Thanks.

If any Intel employee sees this - both lectures don't work well when they're downloaded as a zip file.

It launches, you can hear the speech - but the slides don't show on the screen.

On the web it works fine.

Hi Shai Kon,

We was able to see this as well. we will get our Intel IT to fix this .

Thanks

In the .zip file, run Launch_Presentation.exe. This will run the training. The instructions supplied when you registered should have mentioned this.

Steve was right, I will had our IT to have a readme.txt files for enhancment.

There is NO file named Launch_Presentation.exe in the zipped archive
