Agilex‑7 F‑Tile Dynamic Reconfiguration Conflict Between HDMI and SDI RX

Hello,

I am working on a design targeting an Agilex‑7 device (AGFB014R24C2I2V) using Quartus Prime Pro 23.2. The design includes two video RX interfaces on the same F‑Tile, both configured as input-only:

  • HDMI (TMDS only)
  • SDI‑12G

Both IP cores use dynamic reconfiguration to adapt the transceiver to the detected input frequency:

  • HDMI: Mixed single-rate PHY (63 profiles)
  • SDI: Multi-rate PHY (4 profiles)

Since both IPs are located in the same F‑Tile, they share:

  • A single dynamic reconfiguration block (through the arbiter from the provided IP example)
  • The same System PLL

Observed Behavior

  • When only one RX IP is instantiated (either HDMI or SDI), the link comes up correctly and video is received as expected.
  • When both RX IPs are instantiated simultaneously:
    • HDMI link initializes and operates correctly.
    • SDI PHY fails to lock to the input signal.

Debug Observations

Using SignalTap on the dynamic reconfiguration interface:

  • The SDI reconfiguration state machine cycles through all profiles.
  • Each reconfiguration completes successfully (no errors reported).
  • Despite this, the SDI RX never achieves lock.

Suspected Cause

This appears to be potentially related to a resource conflict or incorrect sharing configuration within the F‑Tile, possibly due to QSF assignments or transceiver resource allocation.

However, the exact root cause is unclear, and I may be overlooking a configuration requirement for:

  • Shared dynamic reconfiguration usage
  • Multi‑client arbitration
  • F‑Tile resource partitioning

Additional Information

Below are the QSF assignments used to configure the dynamic reconfiguration IP. For brevity, only the first and last HDMI profiles (out of 63) are included.

Any guidance on:

  • Proper sharing of dynamic reconfiguration between multiple RX IPs on the same F‑Tile
  • Known limitations or requirements for mixing HDMI (TMDS) and SDI PHYs
  • QSF settings that could cause this behavior

would be greatly appreciated.

Thank you.
