Agilent Technologies InfiniiVision MSO N5406A FPGA Dynamic Probe for Xilinx Data Sheet Figure 1. FPGA dynamic probe for Xilinx used in conjunction with an Agilent InfiniiVision 6000 or 7000 Series MSO provides an effective solution for simple through complex debugging of systems incorporating Xilinx FPGAs. The challenge You rely on the insight a MSO (mixed-signal oscilloscope) provides to understand the behavior of your FPGA in the context of the surrounding system. Design engineers typically take advantage of the programmability of the FPGA to route internal nodes to a small number of physical pins for debugging. While this approach is very useful, it has significant limitations.
● Since pins on the FPGA are typically an expensive resource, there are a relatively small number available for debug. This limits internal visibility (i.e. one pin is required for each internal signal to be probed).
● When you need to access different internal signals, you must change your design to route these signals to the available pins.
