Using Output Results From a Previous
Simulation
The .CHRSIM command enables you to use the output of previous simulations as input to the
current simulation. The previous simulation data must have been generated by a DC sweep or a
transient analysis. The simulator assigns to the node IN of the current simulation, the output
obtained at node OUT in the file FILE.wdb.
