vphy_v1_3 driver XVphy_PllInitialize function QuadId parameter

Jump to solution

Hi, Is there any place that documents what values should be passed into the various parameters, specifically I am interested in the QuadId parameter.   I am not sure what value to pass into this.

 

I am developing a DisplayPort solution and on the KC705 example project all DP signals go into the GTX quad 118, which is the top quad in the package, and the driver for this application uses "0" for the QuadId parameter.   I would have thought the value would have needed to be 118.   Or does "0" mean "apply to all quads"?

 

It would be nice if there was some documentation somewhere that explained what values should be used in all these parameters.

 

From:C:/Xilinx/SDK/2016.4/data/embeddedsw/XilinxProcessorIPLib/drivers/vphy_v1_3/doc/html/api/xvphy_8c.html

Hi @tim_severance,

 

The answer is in PG230 p81:

I guess this is just because the VPHY includes a GT wrapper which can do multiple bank or it could be for future improvement.

 

Currently, the only configuration is 0. It means the current quad.
