Channel to Channel skew with ALTDDIO_OUT

[MYota1]

Hello,

I am using couple of ALTDDIO_OUT channels in Cyclone 10 LP and map them onto true LVDS pins. Is there a way to get the channel to channel skew analysis by the Timing Analyzer ? when I try the 'Reprt TCCS' I get 'No dedicated SERDES Transmitter circuitry present in device or used in design'. Is there another way to get the skew ?

Thank you.

Hi ,

Is it possible to see the report from the Qaurtus for cylcone 10 LP the TCCS specification is given in data sheet page no:27

Thank you. But this is the datasheet. I am interested in the actual value that comes up from the design.

To answer your question , the TCCS value will be provided only for the serdes , you can find the calculation from the IO user guide of c10lp
