# Vlsir Tools 

Python-based tools and utilites for working with the Vlsir IC design schema. 

## Netlisting 

FIXME! Details here. 

## Spice-Class Simulation 

VlsirTools includes drivers and result-parsers for popular spice-class simulation engines including: 

```python 
class SupportedSimulators(Enum):
    """Enumerated, Internally-Defined Spice-Class Simulators"""

    SPECTRE = "spectre"
    XYCE = "xyce"
    NGSPICE = "ngspice"
```

The primary entry-point for simulation is `vlsirtools.spice.sim`. By default, `sim` runs your chosen simulator in parallel over the list of `SimInputs` provided as `inp`.

```python
def sim(
    inp: OneOrMore[vsp.SimInput], opts: Optional[SimOptions] = None
) -> OneOrMore[SimResultUnion]:
```

The `sim` function takes as input one or more `vlsir.spice.SimInput`s and a set of simulation options (`vlsirtools.spice.SimOptions`), and returns one of two result-types depending on its input `options`.

```python
class ResultFormat(Enum):
    """Enumerated Result Formats"""

    SIM_DATA = "sim_data" 
    VLSIR_PROTO = "vlsir_proto" 
```

The `VLSIR_PROTO` result-format returns a `vlsir.spice.SimResult` object, which is a protobuf-encoded representation of the simulation results. The `SIM_DATA` format instead uses the types defined in `vlsirtools.spice.sim_data`, a python-native combination of dataclasses and numpy arrays. The former is generally more convenient for sharing with other programs, and the latter for further in-Python processing. 

### Simulator and Analysis Support

Each spice-class simulator includes its own netlist syntax and opinions about the specification for analyses.
