The purpose of a PXI slot path is to describe the PCI bus hierarchy in a manner independent of the PCI bus number. PXI slot paths are a sequence of values representing the PCI device number and function number of a PCI module and each parent PCI bridge that routes the module to the host PCI bridge (bus 0). Each value is represented as " dev[.func] ", where the function number is listed only if it is non-zero. When a PXI slot path includes multiple values, the values are comma-separated. The string format of the attribute value looks like this: device1[.function1][,device2[.function2]][,...] An example string is " 5.1,12,8 ". In this case, there is a PCI-to-PCI bridge on device 8 on the root bus. On its secondary bus, there is another PCI-to-PCI bridge on device 12. On its secondary bus, there is an instrument on device 5, function 1. The example string value describes this instrument's slot path."#
