Thread starter sahasra Start date Sep 27, This results in the plot shown in FIG 11 where the voltage has been increased by a factor of 3.

Indeed LTspice also recognises the variables 'time' and 'pi' and these can be used to manipulate the waveform accordingly. Stepping through parameters. It is possible to perform multiple back to back simulations with different component values. FIG 12 shows a simple non inverting amplifier. By relabeling the feedback resistor value to 'R' instead of, say, 10k and putting it in curly brackets tells LTspice to treat the value as a variable.

Any number of parameters can be made into variables, however LTspice will run simulations on all the different combinations of each value.

The above circuit applies a mV sinewave to an amplifier with gain of 2, 3 and 4. To determine which waveform corresponds to which value of R, left click on the V out icon to bring up the cursor, then use the UP and DOWN arrows on the keyboard to move the cursor from one waveform to another. Right clicking over the vertical cursor brings up a dialogue box indicating which value of R has been used, as shown in FIG Thus if you want to see what V pwl looks like when multiplied by 3, simply right click over the icon and edit it as shown in FIG 10 FIG 10 This results in the plot shown in FIG 11 where the voltage has been increased by a factor of 3.
