Waveform Editor

Waveform Editor Introduction



The Waveform Editor is a tool for entering simulation vectors and viewing simulation results.

In the Waveform Editor, you can create Vector Waveform Files (.vwf) that contain input vectors for simulation. You can also use vector source files, VWFs, and Vector Files (.vec) for simulation with the Simulator. For backwards compatibility with MAX+PLUS® II, the Quartus® II software can read MAX+PLUS II VEC Files and Table Files(.tbl).

NOTE You cannot use Quartus II waveform files for design entry, and they cannot be compiled. Also, the Quartus II Waveform Editor cannot read MAX+PLUS II Simulator Channel Files (.scf) or Waveform Design Files (.wdf), but can read VEC Files. To convert MAX+PLUS II SCFs to VWFs, you must first save the SCFs as Table Files in the MAX+PLUS II software. Then you can read the Table Files into the Quartus II software and save them as VWFs. However, sometimes the Quartus II software does not recognize bus names in converted MAX+PLUS II waveform files. To avoid this behavior, you can find the group name or individual bits in the Node Finder and copy and paste the node names in a new waveform file.

You can open an existing waveform file, or you can create a waveform file by specifying input logic levels as graphical waveforms. Waveform files can contain both logical and state machine inputs, and combinatorial, registered, and state machine outputs.

You can modify whole waveforms or waveform intervals and create, edit, and sort nodes and groups. You can overwrite and insert new logic levels on a waveform. In addition, you can change the order of the nodes and groups for a simulation, add comments to the waveforms, create multiple time bars to mark the waveforms, and compare waveform files.

Together with the Simulator, the Waveform Editor allows you to view the results of timing simulation or functional simulation. You can save user-defined, Simulator-generated, or actual device outputs in a VWF. You can compare simulation outputs to user-defined outputs in the current VWF, or to actual device outputs that show simulation results.
