Invoking Eldo<br />

To invoke Eldo and run a simulation from the command line use the <strong>eldo</strong> command:<br />

<strong>eldo</strong> cir_filename.cir [arguments]<br />

Where cir_filename is the name of the netlist control file (.cir) to be simulated. cir_filename is<br />

mandatory. All other command line arguments are optional.<br />

All setups described in this chapter are optional. You are encouraged to run your initial Eldo<br />

simulations using the default settings before applying alternatives.<br />

Tip<br />

For a full list of arguments see “Eldo Arguments” in the Eldo Reference Manual.<br />
