Analyzer - Scan to Change, Scan to Value

031_analyzer_scan : Analyzer - Scan to Change, Scan to Value

Minimum Required Versions: SILOS 4.12.1.C

Example 031_analyzer_scan, the circuit is a newspaper vending machine implemented as a Verilog gate level design. The Gateway schematics for the testbench and circuit as well as the netlist and the library files vend.gv and abc_100.v.

This example demonstrates the SILOS graphical user interface Data Analyzer waveform viewer Scan to Change and Scan to Value features.

Analyzer - Scan to Change

  • You can scan to change in a waveform state, or scan to a particular waveform value. Easy scanning and panning saves time when debugging.
  • Open the project gate.spjx and run the simulation.
  • Open the Analyzer window from the toolbar.
  • To demonstrate scanning to change, highlight the signal "clock" in the name list box and click on the 1> toolbar button to scan the T1 marker to the right.
  • The state value for clock waveform in the Value column will change as you scan the T1 marker edge to edge.

Analyzer - Scan to Value

  • To demonstrate scanning to a value, click on the drop down arrow for the Scan to Change box on the main toolbar, and choose the Enter Scan Value selection.
  • Enter the value 1 in the box on the main toolbar, and click on the 1> button on the Main toolbar to scan the T1 marker to the right as it matches each value of 1 for the clock signal.
  • Scan to Value can be used to scan to the value for a bit, a vector, or a symbolic name because Scan to Value does a character match.
  • The ? character can be used as a don't care character, such as ?ff? would match with 1ff3 and ffff.
