Trace Command

The trace command is used to set up a simulation trace while a simulation is running. To set up a trace before a simulation is started, use the .TRACE or .GRAPH simulator controls.

Trace signal-name trace-id



Net name or pin name for voltage or current to be traced.


Integer value used to group traces together on the same graph. All traces with the same trace-id will go to the same graph.


Traces set up with this command only remain in effect until the end of the simulation. A Trace command executed before a simulation starts will have no effect.
