Multiple logfiles and datasets
6-96 Multiple logfiles, datasets and virtuals ModelSim Xilinx Users Manual
In the illustration above, the Wave window is split into two panes. The top pane
shows the dataset of the current simulation. (The default dataset prefix is "sim".)
The bottom pane shows a dataset in the view mode only. (The default dataset
prefix is "view".) The sim-mode dataset is located in the active pane, as indicated
by the white bar in the left margin.
New panes are created with the Wave > File > New Window Pane menu
selection. When multiple window panes exist, the add wave command
(CR-23)
adds signals to the active pane by default. Click in a pane to make it active.
Opening and viewing datasets
Logfiles may be opened using either the Main > File > Open > Open Dataset or
Wave > Open Dataset menu selection. Opening datasets in this manner returns
the View Dataset dialog box, allowing you to specify the dataset name for the
logfile.
