FPGA Editor PROBE

By providing access to the internal state of Xilinx devices, PROBE delivers extremely efficient physical debugging support.

The PROBE capability within the FPGA Editor tool allows you to quickly identify and route any internal signal to an unused I/O pin. Once routed to the pin, you can then view that signal’s real-time activity using normal lab test equipment such as logic/state analyzers and oscilloscopes. PROBE is very easy to use and it makes your lab debug cycles as quick and efficient as possible.

PROBE gives you a simple, natural way to observe any internal signals in your design and analyze their switching behavior with essentially no impact on design performance. The signals are viewed in real-time, so you are sure to have the most accurate picture possible on how your design is functioning in it’s actual operating form and environment.

Your HDL design effort only needs to focus on the device’s primary intended function because all of PROBE’s power can be accessed automatically during the lab-debug phase of your project design cycle—there is no need to guess before lab debugging which signals you wish to analyze. PROBE easily guides you through the debug phase, so you can pick which signals need to be observed at any time during the process, and changes to the signal list can be made instantaneously.
