2014.1 AXI BFM - ERROR: RVALID from slave is not zero (reset value) - AMBA AXI SPEC V2 - Section 11.1.2 Reset

描述

I use an AXI4 BFM master to simulate my custom IP with s_axi port WRITE_ONLY mode.

After a reset, I receive the following error:

ERROR: RVALID from slave is not zero (reset value) - AMBA AXI SPEC V2 - Section 11.1.2 Reset

 

The master m_axi interface from AXI BFM is in READ_WRITE mode.

However my s_axi is WRITE_ONLY, so I do not have an RVALID signal for this interface.

解决方案

This error occurs because the master bfm checks at reset time if the signals from the slave are at the expected reset values.

To work around the issue, you can disable reset value checks by using the following API task:

set_disable_reset_value_checks(1)

 In Vivado 2014.3, AXI BFMs support READ_ONLY and WRITE_ONLY interfaces.
