VCD+ (vpd) File Generation
Note:
The $vcdpluson/off commands increment/decrement an
internal counter for each signal to be recorded. If multiple
$vcdpluson commands cause a given signal to be saved, the
signal will continue to be saved until an equivalent number of
$vcdplusoff commands apply to the signal. This approach
allows multiple users to instrument the Verilog sources to meet
their individual recording requirements for the same simulation run.
$vcdplusflush
The $vcdplusflush task flushes to the VCD+ data file any value
changes that have been reported by the simulator but have not yet
been written to the VCD+ data file.
Syntax:
$vcdplusflush;
$vcdplusautoflushon
When simulation stops, the $vcdplusautoflushon task
automatically flushes to the VCD+ data file any value changes that
have been reported by the simulator but have not yet been written to
the VCD+ data file.
Syntax:
$vcdplusautoflushon;
$vcdplusautoflushoff
The $vcdplusautoflushoff task turns off the automatic flush
(enabled by the $vcdplusautoflushon task).
Syntax:
