Couldn't get correct value from ace in explore without hardware mode.

Hi mataway ,

Thank you for getting in touch,

Unfortunately, the Explore without Hardware mode is limited in that the register map will store values that are written to it, however dependent behavior such as changes in read-only status registers will not be modelled when the relevant evaluation board is not connected.

In the case of the AD9081, the ADS9 and MicroZed run an eRPC server which is the mechanism that ACE uses to interface with the part. This is why you are getting the eRPC errors, as no board is present so ACE cannot communicate with a server and so the transaction fails.

Unfortunately, you will not be able to read back any register data for the AD9081 in ACE without having hardware attached. You could try posting your desired configuration and what register data you are looking for in the FPGA Reference Design forum, one of the product experts may be able to help you there:  Q&A 

Thanks,
Best regards,
