Datasheet report with respect to internally generated clock

Hello,

 

We have a source synchronous interface (SPI) in which we generate the output clock and data to send to another device. In turn, the other device generates return data, sends it back, and it is latched using the clock we generated to send our data with. 

 

We have constrained the interface and are confident we should meet timing, but the board designers would like an external timing spec from the datasheet report so they can verify timing at the board level. Unfortunately, when we generate the datasheet report it's always with respect to the input pin of the reference clock used to generate our output clock. Is there a way to an internally generated output clock pin?

 

I saw the -group option in the report_datasheet command but it still doesn't seem to give us what we want, especially on the input path. Is there any other way?

 

Thanks,

David

Re: Datasheet report with respect to internally generated clock

Did you ever get an answer to this?  I'm in a similar situation
