I am evaluating the SDI IP and I have a couple of issues regarding the use of the Audio Embed IP.
Regarding the observation group 1 is required to be enabled so that other group can work, for your information, this is a known issue with the SDI Audio Embed IP. As a workaround, you would need to enable the group 1 first. Sorry for the inconvenience.
Regarding the 20 bit audio observation, would you mind to further elaborate on the observation? Probably some simulation in Modelsim will be helpful for further understanding. Thank you.
By the way, just would like to check with you which Quartus version are you observing this issue? As I check in the KDB database, this issue seems to be observed previously in Q17.0. I understand that Engineering will be fixing it in the future Quartus release.
As I understand it, the SDI Audio IP for Quartus 19.2 has been recently released. Would you mind to try with the 19.2 audio IP to see if similar issue still persist?
Please let me know if there is any concern. Thank you.
Thanks for your update. I understand that you are using Qstd and CV devices. Thus, you are unable to upgrade to Q19.2Pro. As a workaround, you might need to always enable the Group 1 currently. Sorry for the inconvenience.
I've just noticed that Quartus V19 has been released, but along with that they have removed support for SDI IP for Cyclone V. Can I use SDI II IP with the SDI audio IP? What are my options?
Sorry as I am not aware of the specific restriction. For your information, I have recently tested running SDI II IP with Audio IP in Q17.0Std and things seems to be working as expected.
Probably you can help to refer me to the specific link which is related to the restriction that you mentioned so that I could further follow up from there. Thank you.
