Hi

I’m building a tetsbench where I need an APB interface, I wounder if there exists such BFM for UVVM. I have seen the AXI4-lite BFM, but it seems to miss APB.

Hi,

There is no APB BFM in UVVM, but it should be quite simple to make one from the AXI-lite BFM, or maybe even better and easier - use the SBI BFM as a starting point. It would be great if you could share the APB with the UVVM community if you implement this 🙂

Hi,

No, I’m sorry, but there is still no APB BFM for UVM.  
As previously mentioned (to Bengt), it would be great if you could provide one.  
It should be quite simple using the SBI BFM as a starting point, once you understand the actual APB protocol.
