xschem - Man Page

schematic capture and netlisting EDA tool


xschem [options] [inputfile]


Xschem is a schematic capture program, it allows creation of hierarchical representation of circuits with a top down approach.


-h, --help

Print help and exit.

-n, --netlist

Do a netlist of the given schematic cell.

-v, --version

Print version information and exit.

-V, --vhdl

Set netlist type to VHDL.

-S, --simulate

Run a simulation of the current schematc file (spice/Verilog/VHDL, depending on the netlist type chosen).

-w, --verilog

Set netlist type to Verilog.

-i, --no_rcload

Do not load any xschemrc file.

-o, --netlist_path

Set output for netlist.

-t, --tedax

Set netlist type to tEDAx.

-s, --spice

Set netlist type to SPICE.

-3, --a3page

Set page size for pdf export to A3.

-x, --no_x

Dont use X (only command mode).


Do not use tclreadline, empty tcl shell prompt, dump activity on stdout for remote controlling other software.

-z, --rainbow

Use a raibow-looking layer color table.

-W, --waves

Show simulation waveforms.

-f, --flat_netlist

Set flat netlist (for spice format only).

-r, --no_readline

Start without the tclreadline package ( this is necessary if stdin and stdout are to be redirected for example to /dev/null).

-c, --color_ps

Set color postscript.

--plotfile <file>

Use <file> as output for plot export (png, svg, postscript/pdf)

--rcfile <file>

Use <file> as a rc file for startup instead of the default xschemrc.

-p, --postscript, --pdf

Export pdf schematic.


Export png schematic.


Export svg schematic.

-q, --quit

Quit after doing things (no interactive mode).

-l file, --log file

Set a log file.

-d n, --debug n

Set debug level: 1, 2, 3,...: C program debug, -1, -2, -3...: TCL frontend debug.



default configuration.


user configuration; if exists overrides settings from default configuration; may be partial: settings not overridden will remain as set from the system config.


local/per-project configuration; if exists overrides settings from the user configuration and default configuration.


builtin essentials, such as font and missing symbol graphics.
