2.2. Tools for Monitoring RTL Nodes

The Signal Tap logic analyzer, Signal Probe, and LAI tools are useful for probing and debugging RTL signals at system speed. These general-purpose analysis tools enable you to tap and analyze any routable node from the FPGA.

  • In cases when the design has spare logic and memory resources, the Signal Tap logic analyzer can provide fast functional verification of the design running on actual hardware.
  • Conversely, if logic and memory resources are tight and you require the large sample depths associated with external logic analyzers, both the LAI and the Signal Probe tools simplify monitoring internal design signals using external equipment.
