## Spice export

This chapter of the user manual is dealing with the raw spice workflow, assuming the user wants to understand the process on the spice level. There's an alternative, a higher level abstraction, called sim. Both are also covered by the simulation tutorial.

Raw spice export topics:

- model selection
- spice-specific pinout
- node 0 , the ground network
- bridges , useful for mixed mode (analog+digital) simulation
- full list of symbol, terminal and net attributes used for the raw spice workflow

## Standard features of export_spice

Type: netlist.

### Attribute usage

For components the following attributes are used to construct file-format specified fields:

- network's spice/gnd is used to select the ground network, node 0
- component's device is printed as comment when debug is enabled
- component's display/value (fallback: value)
- component's display/spice/params (fallback: spice/parans)
- component's spice/model
- component's spice/model_card
- component's spice/model_card_uname
- component's spice/file_header
- component's spice/model_include
- component's spice/command

Extra attributes with export name are not exported: the file format is positional and does not support arbitrary attributes.

### Omit and DNP

The plugin will not export components and networks that have the display/omit attribute set.

The plugin ignores DNP.
