Binaries available at releases!
A program written in Go and using plotinum that interprets raw spice files and produces pretty plots in .svg, .png, .jpg, .jpeg, .eps, .tiff, .pdf formats.
- Plotting specific variables
- Calculating expressions
- Plotting expressions
- Complex variables
- Calculating expressions better
go get github.com/norcalli/spiceplotThis will install spiceplot into your bin directory for your Go installation.
bcfor expressions. This will be removed eventually.- Uses
plotinumand myrawspicepackage, but those are automatically installed.
Usage: ./spiceplot [flags] <rawfile> <output>
Supported formats for the output are: .svg, .png, .jpg, .jpeg, .eps, .tiff, .pdf.
Possible flags:
-e="": Comma separated string of expressions to evaluate
-v="": Comma separated string of variables to plot
In the examples, I am using ngspice. You can use ./testobot.sh examples/2b to automatically generate plots with ngspice. I've also provided some .raw files under examples to play with which were generated from ngspice.
ngspice -b examples/2b.net -r examples/2b.raw >/dev/null
./spiceplot -e 'v(b)-v(e)' examples/2b.raw examples/2b.svg
