About Design Limitations and Known Issues
In the "GTS SDI II IP User Guide", section 8. Design Limitations and Known Issues states a known issue: "High bit error rates are observed in recovered data." It also states that there is no workaround in the current version of Quartus, but are there any plans to address this issue? https://www.intel.com/content/www/us/en/docs/programmable/823539/25-3/design-limitations-and-known-issues.html14Views0likes2CommentsAbout Dual Simplex for Agilex 3
In the" GTS Transceiver Dual Simplex Interfaces User Guide: Agilex™ 3 and Agilex™ 5 FPGAs and SoCs", Note 3 in Table 2, Section 2. Overview, states the following: "DS mode is not currently supported for Agilex™ 3 FPGAs for this protocol." Which future version of Quartus Prime will support Agilex 3 ? https://www.intel.com/content/www/us/en/docs/programmable/825853/25-1/overview.html7Views0likes0CommentsPlease let me know how to get a GTS license for Agilex 5.
I have already some licenses, for example, IP-SDI-II, IP-DP, IP-HDMI and so on. I want to use these IP on Agilex 5. However, Ordering Code is not match the IPs I have when I searched the IP User Guide. SDI => IP-GTS-SDI-II Display Port => IP-GTS-DP Is it possible to get a License of IP-GTS-xxx, if I regenerate in my SSLC ? Or, Need I buy the new licenses for GTS Transceiver? Thanks.26Views0likes2CommentsDelay in SPI-to-Avalon-MM IP Response After MAX10 Reset
Hello everyone, I’m using the SPI-to-Avalon-MM IP to enable communication between an external microcontroller (MSP430) and a MAX10 FPGA (MAX10M50DAF256CG). In my setup, the microcontroller acts as the SPI master, and the FPGA is the slave. The microcontroller also controls a GPIO line connected to a load switch, allowing it to power the MAX10 on or off. The FPGA receives a 26 MHz external oscillator input, which feeds into a PLL. The PLL’s lock signal is used to generate a system reset. Here’s the behavior I’m observing: even after the PLL lock signal asserts and the system leaves reset (measured by routing the lock signal to an external FPGA pin and timing from the moment CONF_DONE goes high), it still takes around 9 ms before the FPGA and the SPI-to-Avalon-MM IP start responding to SPI messages from the microcontroller. My questions are: What could be causing this post-reset delay? Is there a defined startup time for the FPGA and IP to begin responding? I haven’t found documentation on this—are there any relevant resources? Thanks in advance for your help.Solved1.2KViews0likes6CommentsHDMI Intel FPGA IP as Receive with AXIS fails in Analysis & Synthesis of Quartus 24.3 Pro
Hi support, When creating a design with "HDMI Intel FPGA IP" having significant values as: - Direction: Receiver - Enable Active Video Protocol: AXIS-VVP Full - Support FRL: Untick (disabled) Then Quartus 24.3 Pro Build 212 (newest) fails in Analysis & Synthesis with the errors: Error(13224): Verilog HDL or VHDL error at hdmi_rx_core_altera_hdmi_1975_ozylggi.v(771): index 2 is out of range [1:0] for 'cv_vid_de' Error: Failed to elaborate design: Error: Flow failed: Errors generated during elaboration Error: Quartus Prime Synthesis was unsuccessful. 3 errors, 0 warnings Archived project is attached. Question: Is there any known fix or workaround for this problem? Regards M_DK_FPGA PS. It appears that an internal non-designer assigned value PIXELS_PER_CLOCK is assigned to 8, as for FRL enabled, thus causing an internal loop to go out of range.Solved6.4KViews0likes38CommentsDisplayPort TX IP Core Link Training Abort
Hi All, we are using the Intel DisplayPort TX IP core on Cyclone 10 GX FPGA and we see link training failures with a certain sink (monitor) of our customer. Using a DP aux channel analyzer, we see that during the test of voltage levels and pre-emphasis, the DP TX core aborts the link training process instantly after about 60 ms. This is caused due to a delay behavior of the sink: Each time, after the DP TX core writes training pattern sets (0x102) or training lane sets (0x103), the sink answers the next 8 source status reads each with AUX_DEFER, until finally providing the requested status. This results in a long duration of the whole link training process, which is aborted by the DP TX core after about 60 ms. Tests of the monitor at a commercial GPUs shows that the link training process takes more than a second until finally succeeds. We have no link training problems with other commercial monitors. Questions: Why does the link training process not complete? We expect that there is some kind of internal timeout within the DP TX core and ask of how we can change this value. We knew that within the sink (monitor) works a Xilinx DP RX IP core, so probably there are pre-known incompatibilities between Intel and Xilinx DisplayPort cores? Note: We use dp tx core version v20.0.1, config without support for DP 1.4 We use quartus pro version 22.3 I attached two aux channel analyzer logs, where the AUX-DEFER packets and the DP TX abort can be seen. I had to compress them to zip due to the forum upload restrictions. Thank you in advance! Stefan3KViews0likes10CommentsHow to switch the HDMI PHY reference clock to the HDMI Rx TMDS clock ?
Hi In the document "HDMI PHY Intel FPGA IP User Guide" ver. 2022.10.31 (newest) section "5.1.2. Dynamic Reconfiguration" it is described that: The RX reconfiguration management is handled predominantly by the RTL. The software is mainly used to switch the reference clock over from the fixed rate clock to the RX TMDS clock (via IOPLL). This is because the transceiver requires a clock to be present at power-up. However, in section "5.1.5. RX PHY Address Map" the register description does not have any register that handled such switch of the clock. Also, based on the frequency of the output clock rx_clk[0] I can seen that is is the reference clock at fr_clk divided by 2, thus not the HDMI TMDS clock, so switch is required in order to get the correct clock on rx_clk for data to the HDMI core. Question: How to switch the HDMI PHY reference clock to the HDMI Rx TMDS clock ? Thanks in advance for any help. Br M_DK_FPGASolved4.7KViews0likes18Comments
