Hi,
Thank you for your inquiry regarding the Dynamic Phase Control Unit (DPCU) module referenced in the CPRI IP User Guide.
To provide you with an update, I have attempted to generate the CPRI IP example design; however, I was unable to locate a distinct DPCU module within the generated deliverables. I am currently following up internally with the factory team to clarify the availability and access method for this module.
I will keep you informed on the progress by end of next week or as soon as I receive a valid update from them. In the meantime, please feel free to reach out if you have any additional questions or if you do not hear back from me.
Thank you for your patience and understanding.
Thank you very much for your explanation! Looking forward to your update.

Hi,
Just to keep you posted that I am still pending for Factory's valid response on this. I will continue to follow up with them and update you again on the progress by end of the week or as soon as there is any valid response. Please ping me if you do not hear back from me. Sorry for the delay. Thank you.

Hi,
I’d like to share an update based on a response from the factory team. They have confirmed that the DPCU block is packaged within the CPRI IP, and it can be instantiated directly at the top level using the pll_dpcu module. This can then be connected to the IO PLL as needed.
Below is an example of how the instantiation would look:
pll_dpcu #(
// parameters
) pll_dpcu_inst (
.clk (clk),
.reset_n (rst_n)
// ...
);
I’ve tested this instantiation on my side and confirmed that the module appears correctly after Analysis & Synthesis in Quartus completes.
Please try this approach and let me know how it goes, or if you have any questions or issues along the way.
Thank you.
