    The Verification Academy offers users multiple entry points to find the information they need. One of these entry points is through Topic collections. These topics are industry standards that all design and verification engineers should recognize. While we continue to add new topics, users are encourage to further refine collection information to meet their specific interests.

    The Verification Academy is organized into a collection of free online courses, focusing on various key aspects of advanced functional verification. Each course consists of multiple sessions—allowing the participant to pick and choose specific topics of interest, as well as revisit any specific topics for future reference. After completing a specific course, the participant should be armed with enough knowledge to then understand the necessary steps required for maturing their own organization’s skills and infrastructure on the specific topic of interest. The Verification Academy will provide you with a unique opportunity to develop an understanding of how to mature your organization’s processes so that you can then reap the benefits that advanced functional verification offers.

Hello,

I'm beginner in UVM, and i try to make a testbench for spi2ahb , i have all files compiled well but fail in SIMULATION step. I have some warning in optimization and elaboration phase, i want to know if these warnings maybe responsible about the failed status for my simulation ?

the UVM_FATAL that i get is : CAN NOT GET VIRTUL INTERFACE AHB

Thanks

In reply to uvm_share:

You need to provide more information. What are the warnings? Which component is printing the FATAL message? What steps have you tried to debug this?

If the fatal error is from a failed call to uvm_config_db, try running with +UVM_CONFIG_DB_TRACE

so the fatal message is resulted by interface ahb, this is my code for configuration of ahb_interface :
if (!uvm_config_db#(virtual ahb_interface) :: get (this, " ", "ahb_interface", vif1))
`uvm_fatal ("U_TEST","CAN NOT GET AHB_VIRTUAL_INTERFACE")

In reply to uvm_share:

And...??? Where is the output from +UVM_CONFIG_DB_TRACE? Filter the log file for just messages with "ahb".

Also, your code segment seems to have a space in the middle of the second argument: " ". If that is really what you have, that could be the bug. It should be "". If not, please be precise if you are asking for help debugging.
