# Wave View: A Python Toolkit for SPICE Simulation Waveform Visualization


[![License: MIT](https://img.shields.io/badge/License-MIT-yellow.svg)](https://opensource.org/licenses/MIT)

Wave View is a powerful yet lightweight Python toolkit for visualizing SPICE .raw files as interactive Plotly figures with minimal code. It loads simulation data directly into a simple {signal_name: np.ndarray} dictionary, supports declarative multi-axis plots via YAML or CLI overrides, and automatically selects the best renderer for Jupyter, VS Code, or headless environments. With case-insensitive signal lookup and robust multi-strip support, Wave View lets you focus on circuit analysis—not plotting boilerplate.

## Features

- **Interactive Plotly Visualization**: Modern, web-based plots with zoom, pan, and hover
- **YAML Configuration**: Flexible, reusable plotting configurations
- **Simple API**: Plot waveforms with a single function call
- **Command Line Interface**: Quick plotting from terminal with `waveview plot`
- **Automatic Environment Detection**: Auto-detection and inline plotting for Jupyter Notebooks, render in browser when running in standalone Python scripts.



## Quick Start

### Installation
```bash
pip install wave_view
```

Wave View provides two common workflows for visualizing your SPICE simulations:

* **Option A: CLI-First** – The fastest way to get from a ``.raw`` file to an interactive plot. Perfect for quick, one-off visualizations.
* **Option B: Python API** – The most flexible approach. Ideal for scripting, custom data processing, and embedding plots in notebooks or reports.


### Option A: CLI-First Workflow

Get from a raw file to a plot in three steps using the ``waveview`` command-line tool.

**Step 1: Generate a Plot Specification**

Use ``waveview init`` to create a template ``spec.yaml`` file from your simulation output. It automatically populates the file with the independent variable (like "time") and a few available signals.

```bash
waveview init your_simulation.raw > spec.yaml
```

**Step 2: Discover Signals**

Find the exact names of the signals you want to plot with ``waveview signals``.

```bash
# List the first 10 signals
waveview signals your_simulation.raw

# List all signals
waveview signals your_simulation.raw --all

# Filter signals using a regular expression
waveview signals your_simulation.raw --grep "clk"
```

**Step 3: Plot**

Edit your ``spec.yaml`` to include the signals you discovered, then use ``waveview plot`` to generate an interactive HTML file or display the plot directly. The command now supports a self-contained workflow where the raw file is specified directly in the YAML.

```bash
# This command will open a browser window with your plot
waveview plot spec.yaml

# You can also override the raw file specified in the YAML
waveview plot spec.yaml your_simulation.raw

# To save the plot to a file instead
waveview plot spec.yaml --output my_plot.html
```

This approach is fast, requires no Python code, and keeps your plot configuration version-controlled alongside your simulation files.

### Option B: Python API Workflow

For more advanced use cases, the Python API provides full control over data loading, processing, and plotting. This is ideal for Jupyter notebooks, custom analysis scripts, and automated report generation.

The API follows a clear three-step workflow:

1. **Data Loading** – Load the raw ``.raw`` file with ``wave_view.load_spice_raw``.
2. **Configuration** – Describe what you want to see using ``wave_view.PlotSpec``.
3. **Plotting** – Call ``wave_view.plot`` to get a Plotly figure.

**Minimal Example**

```python
import wave_view as wv

# 1. Load data from a .raw file
data, _ = wv.load_spice_raw("your_simulation.raw")
print(f"Signals available: {list(data.keys())[:5]}...")

# 2. Configure the plot using a YAML string
spec = wv.PlotSpec.from_yaml("""
title: "My Simulation Results"
x:
  signal: "time"
  label: "Time (s)"
y:
  - label: "Voltage (V)"
    signals:
      Output: "v(out)"
      Input:  "v(in)"
""")

# 3. Create and display the plot
fig = wv.plot(data, spec)
fig.show()
```

**Advanced Example: Plotting Derived Signals**

Because the API gives you direct access to the data as NumPy arrays, you can easily perform calculations and plot the results.

```python
import numpy as np
import wave_view as wv

# Load the data
data, _ = wv.load_spice_raw("your_simulation.raw")

# Calculate a new, derived signal
data["diff_voltage"] = data["v(out_p)"] - data["v(out_n)"]

# Create a spec that plots both raw and derived signals
spec = wv.PlotSpec.from_yaml("""
title: "Differential Output Voltage"
x:
  signal: "time"
  label: "Time (s)"
y:
  - label: "Voltage (V)"
    signals:
      VOUT_P: "v(out_p)"
      VOUT_N: "v(out_n)"
      VOUT_DIFF: "diff_voltage"
""")

# Create and display the plot
fig = wv.plot(data, spec)
fig.show()
```
