Command line help ================= The ``ahkab`` simulator has a command line interface that allows for quick simulation of netlist decks, without the need to load the Python interpreter explicitely. Several switches are available, to set the input and output files and to override some built-in options. Notice that options set on the command line always take precedence on any netlist option or any value set in :mod:`ahkab.options`. Usage: ------ :: ahkab [options] The filename is the netlist to be open. Use - (a dash) to read from stdin. Options: -------- --version show program's version number and exit -h, --help show this help message and exit -v VERBOSE, --verbose=VERBOSE Verbose level: from 0 (almost silent) to 5 (debug) -p, --print Print the parsed circuit -o OUTFILE, --outfile=OUTFILE Data output file. Defaults to stdout. --dc-guess=DC_GUESS Guess to be used to start a OP or DC analysis: none or guess. Defaults to guess. -t METHOD, --tran-method=METHOD Method to be used in transient analysis: implicit_euler, trap, gear2, gear3, gear4, gear5 or gear6. Defaults to TRAP. --t-fixed-step Disables the step control in transient analysis. --v-absolute-tolerance=VEA Voltage absolute tolerance. Default: 1e-06 V --v-relative-tolerance=VER Voltage relative tolerance. Default: 0.001 --i-absolute-tolerance=IEA Current absolute tolerance. Default: 1e-09 A --i-relative-tolerance=IER Current relative tolerance. Default: 0.001 --h-min=HMIN Minimum time step. Default: 1e-20 --dc-max-nr=DC_MAX_NR_ITER Maximum number of NR iterations for DC and OP analyses. Default: 10000 --t-max-nr=TRANSIENT_MAX_NR_ITER Maximum number of NR iterations for each time step during transient analysis. Default: 20 --t-max-time=TRANSIENT_MAX_TIME_ITER Maximum number of time iterations during transient analysis. Setting it to 0 (zero) disables the limit. Default: 0 --s-max-nr=SHOOTING_MAX_NR_ITER Maximum number of NR iterations during shooting analysis. Setting it to 0 (zero) disables the limit. Default: 10000 --gmin=GMIN The minimum conductance to ground. Inserted when requested. Default: 1e-12 --cmin=CMIN The minimum capacitance to ground. Default: 1e-18
