Simulation
To simulate the circuit, all you need do is invoke the Simulate command on the Graph menu (or
use its keyboard short-cut: the space bar). The Simulate command causes the circuit to be
simulated and the current graph (the one marked on the Graph menu) to be updated with the
simulation results.
Do this now. The status bar indicates how far the simulation process has reached. When the
simulation is complete, the graph is redrawn with the new data. For the current release of
Proteus and simulator kernels, the start time of a graph is ignored - simulation always starts at
time zero and runs until the stop time is reached or until the simulator reaches a quiescent
state. You can abort a simulation mid-way through by pressing the ESC key.
A simulation log is maintained for the last simulation performed. You can view this log by
clicking on the simulation advisor at the bottom left of the schematic frame. The simulation log
of an analogue simulation rarely makes for exciting reading, unless warnings or errors were
reported, in which case it is where you will find details of exactly what went wrong. In some
cases, however, the simulation log provides useful information that is not easily available from
the graph traces.
