TCCS and ALTDDIO_OUT

I am using ALTDDIO_OUT channels in Cyclone 10 LP and map them onto true LVDS pins. Is there a way to get the TCCS analysis between the channels ?

My other question: Does the TCCS that is defined in the datasheet, for example for the true LVDS, depends on the IP core being used ?

TCCS is device-specific, not IP specific. You can run the TCCS report in the Timing Analyzer in Quartus to get the value without having to look it up.

Thank you. However when I run the Timing Analyzer to get the value of TCCS I get: "No dedicated SERDES Transmitter circuitry present in device or used in design".

Hi ,

Timing Analyzer provides the transmitter channel-to-channel skew this is serdes not for normal IO

 

TCCS that is defined in the datasheet, for example for the true LVDS, depends on the IP core being used ?

>> device specific , the max value can be find in the data sheet for example page no 38 for the Cyclone 10 GX
