Connections to outside world#
A component can be accessed in more than one way, depending on how the board
is connected to the outside world: pcie
, jtag
or ftdi
.
The path to a component contains two parts, as shown in the Figure below. The immutable part is described by the Map and the rest by the Scenario.

Schematic view of the PCIe400 connections to the outside world. Somme components can be access via 3 types of connections FTDI, JTAG and PCIe. More detailed description is given in the peripheral tree#
