Interactive Window

Scope Control

The Scope Control is used to specify and display the current scope.

Entering a scope and clicking OK is equivalent to using a $scope()

command.

Time Display

The Time Display shows the current simulation time and time units.

The time units are read from the simulator. For Verilog, initially the

units are the unit from the last timescale directive compiled. A

$timeformat() can be used to override this value.

VirSim ignores precision and units string specified in the

$timeformat() command.

Note:

$timeformat() does not take effect until the statement is

executed. A $timeformat() entered interactively takes effect

immediately. A $timeformat() in an initial block, for example,

only takes effect when it is executed. For example, #30 $stop;

entered interactively may mean 30 ps before a $timeformat()

command in an initial block is executed, but 30 ns after. This can

cause unexpected, but correct, results during start-up.
