====== Features highlight ======
**IOscopy** together with **Oscopy** form plotting program for electrical simulation data.

**IOscopy** is a front-end application built on top of IPython. The combination of Python, IPython and oscopy back-end make IOscopy a powerful tool for data viewing and post-processing.
Support for simple arithmetic operations as complex functions like FFT is included.
Input file re-reading (updates) can be triggered by external applications like gEDA suite through D-Bus messaging system, and then IOscopy can call netlist generator and electrical simulator programs automatically.
IOscopy uses oscopy as back-end to manage files, signals, plots.

**Oscopy** is a back-end written in python designed to simplify the electrical design workflow. It allow to read, view and post-process signals with support for automatic dependency tracking.\\
Oscopy can be easily extended to a multi-purpose viewer, as adding new data file formats and new types of plots is really easy.

The mains features of IOscopy are:

  * **Post-processing**: math expressions (arithmetic, trigonometric, boolean, fft)
  * **View**, examine: multiple windows, cursors, zoom with mouse wheel, span
  * Data import: see [[features#Supported input formats|below]]
  * Data export: gnucap, pictures
  * **Dependency tracking** of Signals during input file updates
  * Scripting
  * **Integration** with other tools: Run netlister and simulator from oscopy, run ioscopy from gEDA's gschem
  * D-Bus support: update recursively Signals by sending events from external program (e.g. gschem)
  * [[features#Drag and drop|Drag and drop]] of signals between windows

====== Data examination ======

Zoom with the mouse wheel

====== Supported input formats ======

^ Format ^ Description ^ Notes ^
| Gnucap | Text format from Gnucap | |
| Cazm | Text format from CaZM | |
| Nsout | NanoSim format from Synopsis | Independent variable assumed to be ''Time'' |
| Spice2raw | Berkeley Spice2G6 raw format | Only one dataset per file, ''Date'' and ''Time'' fields not processed |
| Spice3raw | Berkeley Spice3 format | **ascii** and **binary** format supported, real and complex numbers supported. Only one simulation per file. |
| Hspice | Hspice format | **ascii** and **binary** format supported. Only one sweep per file. Auto signals are note returned, only probe signals are. Endianness is not managed in binary mode. |
| Touchstone(r) | Touchstone(r) ''s2p'' and co. from IBIS Open Forum | Version 1 and 2.0 supported. for version 1 uses the file extension to determine the number of ports ('.snp' where n is 1-4). Noise parameter data is read and stored in self.info['noise_param']. Mixed mode parameters of version 2.0 not supported. |

====== Cursors ======

In each Graph, horizontal and vertical cursors can be toggled by using keys '1', '2', '3' and '4'.\\

====== Drag and drop ======

Drop a file into the main window to open it and then drag signals to figures to insert them.
