Simulation Menu Commands 205
Run
This command tells the simulation to proceed as fast as possible.
Other Simulation Speeds
The intermediate speed settings between Stop and Run insert various
amounts of delay between executing successive simulation time steps.
These can be used to slow the simulation progress for convenient observa-
tion.
Single Step
This command simulates one time step. To perform the single step, the
simulator looks at the time value associated with the next signal change
event in the queue, simulates the effect of that event and all following
events scheduled at the same time, then returns to the stopped state. The
actual time value of a single step depends on the nature of the circuit.
Simulation Params...
The Simulation Params command is a general method of setting device and
pin delays and options. If no devices or pins are selected in the circuit, then
this command will be disabled.
The type of dialog that is displayed will depend upon the types of devices
selected, as described in the following table:
Selection Params Box Notes
A single Clock device Clock Params Box Only one clock device can be set
at a time.
A single One Shot
device
One Shot Params Box Only one One Shot device can be
set at a time.
Any other combination
of one or more devices
or pins
General Delay Box Any selected Clock, One Shot,
subcircuit, or other non-delay
devices will be ignored for device
delay calculations. Pin delays can
be set on these devices.
