文档中列出的工具 (40)
内容来自项目文档。服务器握手不会验证每个工具的说明或行为。
ac_structure
Pole/zero structure of an AC response: net order, corner ranges + Q, non-minimum-phase / RHP-zero, transport delay (facts for human review)
agentic
41
apply_schematic_ops
Apply many .asc edits in one transaction; its addcomponent op returns placed pins, bounding box, and overlap warnings, while other mutation ops are acknowledgement-only
bode_metrics
AC/Bode analysis by mode: filter, slope, point, crossing; allsteps=true for per-step results
cancel_job
Cancel a running simulation or batch; kills the simulator process(es)
check_job
Check a job's status by ID, or list all jobs
component_info
Placed component pin positions, bounding box, attributes
configure_sweep
Configure a multi-parameter sweep (linear or log)
create_netlist
Create a new netlist from a content string
create_schematic
Create an empty .asc ready for incremental editing
diff_circuit
Structural diff between two circuit files
edge_metrics
Rise/fall time and slew rate for one transient edge
edit_directive
Add or remove SPICE directives (.tran, .ac, .lib, ...)
export_netlist
Export .asc to .net via LTspice (with diff against previous export)
export_waveform
Full-fidelity CSV egress of one or more signals to disk (all analysis types; tidy/long for .step); accepts device operating-point params (m1.gm/@m1[gm]) — across a .dc sweep this is the gm/ID-table read; returns the path to compute on yourself
get_waveform
Decimated min/max stat-envelope of a signal over a window — see the shape, then re-request a narrower window to zoom
list_components
List components (optional prefix filter) or look up one by reference
measurement_stats
Aggregate .MEAS scalars across a sweep or Monte Carlo run
noise_integral
Integrate a .noise spectral density to total RMS over a band (sqrt(∫ density² df)); reports the band and sample count
operating_point
DC operating point: all node voltages, branch currents, and per-device operating-point params (gm/gds/vth/…) on LTspice (auto .options logopinfo) and ngspice, addressable as m1.gm/@m1[gm]; device= scopes to one device
parameter
Read all .PARAM values or set one
periodic_metrics
Period, frequency, duty cycle, jitter of an oscillating signal
plot_waveform
Interactive HTML chart (transient / DC / Bode dual-panel with acstructure corner + non-minimum-phase markers / noise / .step overlay) written next to the circuit and opened in your browser; for seeing shape, not measuring
query_value
Signal value at a specific time/frequency (or a device operating-point param, m1.gm/@m1[gm]); stepaxis+stepvalue picks a .step run
read_circuit
Read a circuit file (netlist text for .cir, schematic layout for .asc)
reset_schematic
Revert an .asc to its pre-edit snapshot from this session
resonance
AC peaks with Q factor and -3 dB bandwidth per peak
return_loss
Reflection coefficient Γ, return loss (dB), and VSWR from an impedance trace vs a reference z0 (worst-match scan or a single frequency)
run_simulation
Run a simulation — sync for short runs, async (job ID) for long ones; sets batch flags, handles the ngspice headerless-raw dialect, routes raw/log artifacts, surfaces convergence/timeout errors (no hand-parsing a rawfile)
set_component_value
Set one component value, or batch-set many via a values dict
signal_stats
Min, max, mean, RMS, peak-to-peak (dB/phase for AC)
simulation_summary
Full summary: simulation type, signals, measurements, warnings
stability_metrics
Loop-gain stability: all unity-gain / -180° crossings with per-crossing margins
symbol_info
Symbol pin positions, directions, bounding box, description
thd
Total harmonic distortion (THD/THD+N) of a periodic transient via FFT; coherent sampling for an exact result; surfaces every condition
timing_between
Propagation delay between two transient signals
trace_net
Every pin/label/wire on a net at a pin / net:NAME / (x,y); flags accidental shorts
transient_response
Transient response by mode: step overshoot/undershoot/settling, or disturbance droop/overshoot/recovery
validate_netlist
Static pre-flight checks on a netlist or schematic before simulation
wire_pins
Wire two pins by reference with waypoint routing; validates pin collisions, junctions, diagonals (formerly connect, kept as a deprecated alias)
