110 - Aldec Active-HDL: Why do the simulation database and simulation results fail to refresh automatically?

By default, the simulation database and results displayed in the Waveform window do not refresh automatically. Changes to the simulation database are available only after a simulation step is finished or the simulation is stopped.  This means that the display of signal history is frozen until the run command completes (or when the simulation is interrupted by the user or a breakpoint). This behavior can be altered by using the -asdbrefresh argument of the asim command as shown below:

"-asdbrefresh time | @time fs|ps|ns|us|ms|s|sec|min|hr"

The example syntax is shown below:

asim -asdb -asdbrefresh @1ms work.tb

The -asdbrefresh argument specifies time intervals when the simulator should dump signal history to the simulation database.  The default name of the simulation database is wave.asdb.

There should be no space between the number and the time unit. If you specify a value that is too small, the simulator will assume the minimum acceptable time.

Note: You must have access to "Accelerated Waveform" Viewer to use this feature.
