How to share signals on Avalon bus ?

Sorry to hear that you're having trouble. Three options for you:

1. AND/OR the signals together as you desire. In reality, this may be the best option. There shouldn't (please tell me if there is) a problem with always sharing address/data/chipselect per tri-state bridge.

2. Edit the .ptf file of the component you made with component builder and turn on "is_shared" in the relevant SLAVE signal sections. A signal that 'is_shared = "1"' will be shared per tri-state bridge.

3. Use the old interface to user-logic with all of its lovely quirks and limitations. Its still there, located in the 'legacy components' folder of SOPC Builder.

After discussing this with some of our designers I think that the way its done now is actually all right, if not 100% optimial & whiz-bang -- the whole "is shared thing", from the perspective of the component builder and designing user-logic, is a bit skewed as the component builder has no knowledge if how multiple things will be later connected to a single tri-state bridge by the user.
