Hi,
As I understand it, you have some inquiries related to the Mixer II IP in simulation. To ensure we are on the same page, would you mind to further elaborate on the specific issue that you are observing? Probably some screenshots of your simulation issue will be helpful for better understanding.
For your information, to facilitate the debugging, you can start with simple design ie TPG -> CVO, then slowly add more modules to help narrowing specific issue location.
Please let me know if there is any concern. Thank you.
Best regards,
Chee Pin
