CPRI F-Tile Dynamic Reconfiguration

Hi, I use the Q24.2 and have Agilex7 F-Series 014.  I my design I use CPRI Phy over several of my FGTs. I generated the CPRI Phy IP to have 4 line rates (LRs) - LR8 (startup profile), LR7, LR5 & LR...

Hi Arik,

 

Based on my understanding, you have an inquiry related to CPRI PHY dynamic reconfiguration. There does not appear to be any issue with the standard dynamic reconfiguration flow; however, when Recover Mode is enabled, the behavior does not seem to be as expected.

 

I cross‑checked your register write sequence against the F‑Tile DR User Guide and did not observe any specific anomalies.

 

To ensure we are aligned, could you please help clarify the following:

 

  1. When you mention that the recovery “wasn’t succeeded,” could you please elaborate on the exact behavior you observed? For example, are there any error indicators, status register values, or specific symptoms you are seeing?
  2. Have you had a chance to run a ModelSim simulation using a simple single‑channel test design? If so, would you mind sharing the test design with simulation files along with the steps required to reproduce the issue? This would greatly help facilitate further debugging.

 

Please let me know if you have any concerns or questions. Thank you.
