Does Altera supply a avalon-wishbone bridge?

Does anyone know if there is a such bridge from Altera? 

 

Thanks,

I do not believe there is one from Altera. 

 

I do think that the is one in the opencore community. 

 

Or perhaps on Nios Forum?

Altera does not support wishbone bridge for sure.

As far as I know, wishbone interconnect is similar to Altera's avalon interconnect. 

Altera does provide 2 Avalon-MM bridges: pipeline bridge and clock crossing bridge. 

See which one is suitable to your need.

The Wishbone bus connects very easily to the Avalon bus. You just need to add a bit of combinatorial logic. See if this link helps:

There are several examples out there (The OpenCores MAC and I2C cores have been ported to Avalon).

Hi Jake, 

 

Can you show me where to find the examples?

The attached file is a wrapper that I once wrote to connect the OpenCores MAC which has a wishbone slave and a wishbone master to the avalon bus.
