How To
- Pick variables form a list - Press the "+" next to top-right "Add".
The next dialog allows to pick variables and to filter them on different criteria.
- Pick variables from schematic - Press the search button next to top-right "Add".
Push into a sub-circuit by double-tapping it and return with Back button or WeSpice icon.
- Switch lin/log/dB graph - Tap on the variable name in the right-hand list. If the variable has values <= 0, log scale is not available.
By default frequency and magnitude variables start with log scale.
- Separate/join graphs - Per variable - tap on variable name; all - Split/Merge button in the action bar.
- Change X axis - Tap on the "+" next to the X-variable name. You can use any variable as X-axis.
- Get nice parametric graphs - For DC sweeps with two changing variables - Tap on the X-variable name and choose "Multi".
- Perform waveform arithmetic - Tap on the variable name, choose "Arithmetic".
All operations are two-operand (this and the next) - differentiation and integral also require a second operand (usually TIME).
If you concatenate operations, they will be executed top to bottom.
- Show spectrum - Tap on X-axis name (which has to be TIME) and choose "Spectrum". A FFT will be computed on each waveform (result: amplitude).
Arithmetic operations are executed before the FFT. Duplicate variables are not allowed in spectrum mode. Go back by tapping on "SPECTRUM".
- Add a cursor - Tap on the graph. Move the selected cursor by dragging anywhere on the screen.
- Remove a cursor - Tap on the "X" on top of the selected cursor. Or remove both from the menu.
- Adjust cursor selection timeout - Settings > Analysis and Results.
- Load faster - The raw file containing the simulation results can get quite large.
To make it smaller, you can decrease the simulation range, increase the simulation step or relax the simulation accuracy parameters.
Files
- Raw file with all simulation results "Spice.raw" or other .raw file. Text file only (binary not supported).
- Output listing "Spice.out". View the contents with INFO.
- Errors file "Spice.err". View the contents with INFO.
- Graph settings and shown variables are saved in "Results.sys".
