Viewing and Loading Value Text
Value text on the Logic Browser display shows variable data such as
signal load status, data availability, and data values. It is dynamically
updated according to time viewed, signal load status, and display
radix selection. The underlying signal values are obtained either from
a VCD+ history file (post-processing mode) or from a running
simulation (interactive mode).
Any text that is too long to fit in the available space is abbreviated and
followed by an asterisk. Place your cursor over the abbreviated text
and the full text appears in the status bar. Allowable length for value
text is controlled with an X resource. See
Chapter 16, VirSim Setup.
Loading Signal Values
For best performance, the Logic Browser supports incremental signal
loading. An NL indicates that the signal has not yet been loaded for
value display. After a load, the NL value text is replaced by actual
simulation values. A connection with NL value text may require
loading of multiple signals, depending on the expression. To avoid
unnecessary load delays, use the toolbar Load Value Changes icon
and the Logic Browser CSM Load Values commands judiciously.
Because a Logic Browser view may contain hundreds of signals, a
substantial delay may occur when these commands are used with
extremely large files. To avoid lengthy delays, use the appropriate
context sensitive menus to load only signals for specific modules or
port instances.
