Or alternatively, the spice engine can be written as is usual in Unix.
i.e. so that it takes a command line argument netlist and outputs an
output file so that the same schematic capture can use a number of
different engines. This assumes that the schematic capture is setup to
output and start an external engine. There is one I know off that works
in this manner:-)
SuperSpice, a very affordable Mixed-Mode
Windows Simulator with Schematic Capture,
Waveform Display, FFT's and Filter Design.
