Displaying physical signal routing of a system. A diagram of the system may be displayed. The system may include physical components connected via physical connections and logical components implemented on various ones of the physical components. The diagram may include a plurality of icons connected by wires. At least a first subset of the icons may represent logical elements of the system and wires between the first subset of icons may represent logical connections between corresponding logical elements. User input requesting signal routing information of the system may be received. In response, a signal route corresponding to a first logical connection between a first logical element and a second logical element may be visually indicated.
