PICAXE Virtual System Modelling (VSM), is a software circuit simulator that combines a virtual PICAXE chip with animated components and SPICE circuit analysis to produce a simulation of a complete PICAXE project and it operates in real time!

To use the system you simply draw your schematic on screen, using the automated wiring and a library of over 10,000 popular analogue/digital components to build up your circuit. Add voltage/current probes to any point in the circuit and then connect any virtual instrument (e.g. voltmeter, oscilloscope) as required.  Associate your PICAXE basic program to the PICAXE chip and click "run" to watch the circuit in operation!
