Simulator-Aware Node Finder Dialog Box
You open this dialog box by clicking . in Signal Tap.
Running this command intelligently analyzes the circuit to determine the minimum set of nodes that you need to tap to gain enhanced visibility into the selected hierarchy's cone of logic.
Signal Tap can also transform the Signal Tap data into an RTL simulation testbench for any level of the design hierarchy. This simulation testbench allows you to export acquired Signal Tap hardware data directly into your RTL simulator and observe signal states beyond Signal Tap observability.
