DisplayPort

Hi,

I am trying to implement a converter of an DisplayPort-RX to HDSDI-TX. In the simulation the design has a good functionning but during the synthetise (Place and route) I got an error that told me that the design had HSSI PMA conflicts (The CALCLK must be driven by the same source).

I am aware that the PHY-HDSDI and the PHY-DP have a different frequencies and I thought that the quartus will take this consideration to instantiate a different HSSI for each PHY. But when I got this error I am confiouse. and I thank one of the HSSI is used for RX Display and TX HDSDI and this way the conflit occurs.

Now I am wondring if existe any special contraints to resolve this confilt ?

thanks
