gsim is simulation pre/post processor for gschem, ngspice and matplotlib based on Python. Allows easy control of simulation process directly from the circuit in gschem or interactively in Python environment.
Standard simulation - simulation is controlled directly from gschem (see examples), gsim contains a set of predefined components for gschem
- for simple graphic output directly from gschem - instant graphic components a.e.
- plotter for amplitude-phase characteristic
- 2 channel or 4 channel analog scope
- digital scope, x/y parametric scope
- for input of analog and digital blocks of XSpice simulator. Enables the creation of hybrid models, consisting of discrete, block and logic components and their use as regular components in gschem.
Python scripting - simulation is controlled from Python, gsim contains a set of predefined Python scripts
- in interactive mode substitutes parameters of components (functions setPAR, setTRAN, setAC …)
- set of referenced classes gsim_PLOT for implementing instant-graphic components
- set of inherited classes for easy data manipulation (simulation results) in the interactive mode
Additional functions
- simple *.sch files parser
- generates list of a part of the schematics (components, connections...)
- *.net file parser with preferences
- allow use of real components in the simulation, corrects the order of pins for the simulation by real pin name (eg diode - Anode, Anoda, AN, A), eliminates problems with different components for simulation and real proposal of the circuit
- generates block models for XSpice in their specific format based on the components attributes
Example - original line from Spice netlist file for D flip-flop
