Hi,

I want to use a wishbone VVC.  
I got it instantiate now in the test harness.

But I don’t know how to address it.

With SPI I use the SPI\_VVCT identifier.  
I don’t know where the SPI\_VVCT is defined but it works.

I tried to do the same for the wishbone, but none works.  
WISHBONE\_VVCT  
WISHBONE\_VVC  
WB\_VVCT  
WB\_VVC  
all fail.

What is the right one for addressing it?

Rgds,  
Eric
