Details of uvm heartbeat

Hi,

I want some details on usage of uvm heartbeat. What I know is heartbeat is used to understand if some uvm component is alive or not. And we can use this to terminate simulations as well. I need some example code.

Thanks,
Ashish

The reason there are no examples of heartbeat is that you should never use it.

Is there any reason behind that. Does that impact simulation time?

That’s it? You need to give a reason why otherwise it looks like mentor is yet again trying to dictate how we should write our code? Looking at what uvm_heartbeat does I think it should be used it would help me realize when a simulation or DUT is locked up instead of waiting for a long test to complete only to find out it is stalled. So please enlighten us?

Hi ashishk,

You can find a working example of uvm_heartbeat at the link below:

You can pass the run-time argument as +NOERROR or +ERROR to check the HB functionality in normal as well as erroneous scenario respectively.

Hope this helps.
