FPGA design pattern for hub/multiplexer

[mal11]

I have an application with a PCI 7811R where I want to talk to 8 SPI slave devices.

Rather than creating 8 parallel masters, does anyone use a design pattern where I could

select which 4-wire bus to use at a given time?

I think of this as a hub or digital multiplexer?

Any thoughts?

Hi Lewis,

Try using a case structure to select which 4-wire bus to use.
