I see why it is confusing though. The la_oen isn't a tristate enable for the output, it just determines whether to read the register value or the la_data_in.

@Matthew Guthaus I am curious how you would be using the logic analyzer. Did you plan to use a BIST?
I would like to use both and would be great to check if you had something already.

On the old tc? There is nothing except pin outs...

On the new one chip with multiple srams, we are planning to use a scan chain for basic test then the picorv32 and LA for further testing

We have a BIST module but time is short

The LA will drive values that are going to select, set input pins for the SRAMs then capture the outputs

We thought about a WB interface but this is simpler and more flexible
