Dear all,
Moving from DCP1.0 to DCP1.1 I realized that there is a difference for the clock signals coming into green_bs.sv with regards to their sources.
The two I refer to are named Clk200 and Clk100 which are both generated by the same PLL inside the blue bits. In DCP 1.0, connections were as follows:
clock name / sourced by pin:
Clk200 / Pll_output [1]
Clk100 / Pll_output [3]
In DCP1.1 this has changed to:
Clk200 / Pll_output [3]
Clk100 / Pll_output [2]
The constraint files on the other hand do not reflect any potential change in frequency. According to this observation, in DCP1.1 Clk200 is actually a Clk100, and the Clk100 port is a Clk50.
I hope I didn't get anything wrong. Always happy to provide more explanations.
Thanks in advance,
Juri

Confirmed by Intel engineers: There is a clocking bug in DCP1.1 that leads to the observations mentioned in the opening post.
