WebAC, Distortion, or Pole-Zero analysis is run. This is particularly useful if the circuit is large. and you do not want to run a (redundant) ".OP" analysis. METHOD=name. ets the numerical integration method used by SPICE. Possible names are "Gear" or "trapezoidal" (or just "trap"). The default is trapezoidal. WebFig. 5.5: LTSpice curve-tracer arrangement for calculating the i - v characteristics of a MOSFET. The i D - v DS characteristic of the MOSFET is obtained by sweeping v DS through a range of voltages while keeping V GS constant at some value. Here the channel-length modulation factor (lambda) is varied from 0 to 0.05 V-1 in 0.01 V-1 increments. ...

WebJul 20, 2024 · 1 Answer. Sorted by: 5. Quoting Mike Engelhardt (who develops and maintains LTspice): LTspice understands some hspice syntax. For example, it understands single quotes for parameter substitution as well as ".lib 'file.lib' FAST" syntax. It won't usually be able to understand a '$' symbol as the start of a comment in-line. WebWe will be using the version of spice available on Athena called hspice. The basic steps used to simulate a circuit are: Add the hspice locker; Create a .sp file with the circuit information; Run "hspice file1.sp > file1.out" View file1.out to see results of the simulation; Run "awaves" to display and print graphs text and image photography artists
