Hi all! For writing/reading coefficients I made a wrapper to compute the proper reset before accessing the Avalon slave. Writing seems to work fine but reading has issues Considering the FIR II IP...

7 years agoHi Erich,
As I understand it, you observe some behavior mismatch between the signatap vs the user guide for FIR II in both 17.1 and 15.1 especially on the read enable and valid signal. Thanks for highlighting this. This seems to be trending towards user guide related. Would you mind to help to create a simple test design with FIR II only and perform a Modelsim simulation with Q17.1 or later to see if can replicate similar observation? This would be helpful to narrow down to any functional related issue. If Modelsim also shows similar observation, please help to share with me the simulation files so that I could perform replication and highlight to Engineering.
Please let me know if there is any concern. Thank you very much.
Best regards,
