Sorry for the delay. To ensure we are on the same page, just would like to check with you on the following:
1. Are you looking for the SDI Audio de-embed IP support?
2. What is the Quartus version that you are using?
3. What is the FPGA device that you are using?
For your information, starting QPro 19.2, we have SDI Audio IP supported for A10 devices. You may refer to the "SDI Audio Intel FPGA IP User Guide" for further details to see if this is something that you are looking for.
Please let me know if there is any concern. Thank you.
