VVP Protocol Converter Not work
Hello, I am looking for how to use the VVP protocol converter, by converting Altera Stream Video Lite to Avalon Streaming Video. I generate a simple pipeline with Protocol Converter to Frame Buffer on Cyclone 10 GX... Here's the settings of the converter, And the Register settings for this IP, For unknown reason, I am unable able to see the protocol converter ready to work by setting rx ready signal goes "high" on STP. Even when the tx side ready signal is OK. Readback the register, the mode is fine and the CTRL is bit 0 is set already.. What would be wrong on my settings? Please help. Thank you.

Agilex 5 SDI 148.5 and 148.35 MHz refclks
I'm working on a design for the Agilex 5 that is going to need to be able to switch between integer and fractional framerates, and I'm trying to figure out and understand the clocking structure involved. In the GTS SDI II IP User Guide, there is a set of parameters for "Transceiver reference clock frequency" and "Dynamic TX clock switching" under the category "Transceiver Options", however I don't see these parameters in Quartus. Is there somewhere else that I can enable this option to have the two different reference clock frequencies? Do I need this enabled, or is there some other way that I can switch between the two frequencies? In addition, what does the clocking structure look like to do this? Is there a way to provide 148.5 MHz to the board and then generate the 148.35 from a PLL to be multiplexed? Or do I need to provide both clock frequencies separately? If I need to provide both clock frequencies separately, what pins can I use for the 148.35 MHz reference clock? The two differential pairs of reference clocks for the GTS bank are already being used for the System PLL reference clock and the 148.5 MHz. Any help with these questions would be greatly appreciated.

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. # Configure global assignments for SytemPLL set_location_assignment PIN_BH8 -to REFCLKIN_HDMI_13A -comment "Pin Function Name is REFCLK_FGTR13A_Q0_RX_CH0P" set_location_assignment PIN_BJ7 -to "REFCLKIN_HDMI_13A(n)" set_instance_assignment -name IO_STANDARD "CURRENT MODE LOGIC (CML)" -to REFCLKIN_HDMI_13A -entity iWave_HelloWorld set_location_assignment PIN_BP8 -to REFCLKIN_100M_13A -comment "Pin Function Name is REFCLK_FGTR13A_Q1_RX_CH3P" set_location_assignment PIN_BN7 -to "REFCLKIN_100M_13A(n)" set_instance_assignment -name IO_STANDARD "CURRENT MODE LOGIC (CML)" -to REFCLKIN_100M_13A -entity iWave_HelloWorld set_location_assignment PIN_CJ7 -to REFCLKIN_148M5_13A -comment "Pin Function Name is REFCLK_FGTR13A_Q3_RX_CH6P" set_location_assignment PIN_CH8 -to "REFCLKIN_148M5_13A(n)" set_instance_assignment -name IO_STANDARD "CURRENT MODE LOGIC (CML)" -to REFCLKIN_148M5_13A -entity iWave_HelloWorld set_instance_assignment -name IP_TILE_ASSIGNMENT Z1577B_X339_Y0_N0 -to U_VideoIn|U_MGT_SUPPORT.U_PLL|systemclk_f_0 -entity iWave_HelloWorld set_instance_assignment -name IP_BB_LOCATION FGT_REFCLK_0 -to U_VideoIn|U_MGT_SUPPORT.U_PLL|systemclk_f_0|x_hip|gen_refclk_fgt_bb_[0].enabled.inst -entity iWave_HelloWorld -comment "Device Location is x_z1577b|ux_refclk|ux_refclk0" set_instance_assignment -name IP_BB_LOCATION FGT_REFCLK_3 -to U_VideoIn|U_MGT_SUPPORT.U_PLL|systemclk_f_0|x_hip|gen_refclk_fgt_bb_[3].enabled.inst -entity iWave_HelloWorld -comment "Device Location is x_z1577b|ux_refclk|ux_refclk3" set_instance_assignment -name IP_BB_LOCATION FGT_REFCLK_6 -to U_VideoIn|U_MGT_SUPPORT.U_PLL|systemclk_f_0|x_hip|gen_refclk_fgt_bb_[6].enabled.inst -entity iWave_HelloWorld -comment "Device Location is x_z1577b|ux_refclk|ux_refclk6" #

Is it possible to add on-screen display to the SDI output of an SDI II FPGA IP?
I'm considering SDI II FPGA IP. I plan to display on-screen text (text) on the SDI output of our product. I would like to add logic for text composition. Is SDI II FPGA IP compatible with this ?

MIPI CSI IP using M20K ram for 128 bits
I'm looking at the design assistant warnings for my project. And I see some weird usage by the mipi csi 2 core (Agilex 5 device, intel_mipi_csi2 v3.0.0). I'm greedy about my ram blocks, and I do not think it is reasonable for an IP core to use this for deskew. It's a problem because we use multiple mipi streams.. so it seems like a huge waste of M20Ks. Why arent they using MLABs? Example location: <my_system>|intel_mipi_csi2_0|intel_mipi_csi2_0|mipi_rx_protocol_inst|mipi_rx_ppi_inst|gen_per_lane[2].gen_per_byte[1].deskew_dcfifo_inst|auto_generated|fifo_altera_syncram|altera_syncram_impl5|ALTERA_SYNCRAM <my_system>|intel_mipi_csi2_1|intel_mipi_csi2_0|mipi_rx_protocol_inst|mipi_rx_ppi_inst|gen_per_lane[0].gen_per_byte[0].deskew_dcfifo_inst|auto_generated|fifo_altera_syncram|altera_syncram_impl5|ALTERA_SYNCRAM Any way to fix this? or a variant IP that fixes it? Thank you. Regards.

Display port TX SST not working.
Hi, I am working on an existing project where Display Port Transmitter MST (multi stream) is already present and working. In the current version I just need to convert that transmitter into a Dispaly Port TX SST (single stream). The result is that, starting from the design example i got a version which works only up to 3840x2160 30Hz and does not at 3840x2160 60Hz. In both cases the training is completed and lane allocated adt 5.4GHz. Bun in tha case of 60 Hz I do not see any image. The Quartus Prime Pro used is 17.1.2 for Windows. I do not know where to check for debug more. Kind Regards, Paolo.

Stratix 10 Transceiver PHY bonding and multiple TX PLL clock inputs (for DisplayPort TX)
We are using a Stratix 10 L-Tile/H-Tile Transceiver Native PHY to implement a DisplayPort TX and RX. The transceiver is set as Basic (Enhanced PCS), TX/RX Duplex. The TX PMA is set as Non bonded, with 2 TX PLL clock inputs. One of the TX PLL clock inputs is driven by a fPLL and used for rates from 1.62G up to 13.5G. The other clock input is driven by two ATX PLLs (one working as Main PLL, the other as GXT Clock Buffer) and used for 20G rate. This works ok. The problem is that DisplayPort requires controlled skew between the 4 TX channels. That is, we need bonding for the 4 TX channels. If we set the TX PMA as "PMA only bonding" it seems we cannot have anymore multiple TX PLL clock inputs but just a single one. How can we use the Stratix 10 PHY to implement DisplayPort TX rates from 1.62G up to 20G with 4 bonded channels (= 4 lanes)?
