This allows register and/or address monitoring and also allows you to add variables from the variables window for inspection. The other major tool at your disposal for single step debugging is the watch window. For example, if malformed characters were appearing on the LCD display setting a hardware breakpoint on the busy line would be a good place to start investigating. If a problem is identifiable as a hardware fault, then using hardware breakpoints will pause the simulation whenever the fault condition occurs. 8051 SIMULATOR FOR WINDOWS CODEIn addition to traditional debugging where you set one or breakpoints in your source and then step the code when they are triggered, Proteus allows you to set breakpoints on the schematic so that a hardware condition can trigger a breakpoint. 8051 SIMULATOR FOR WINDOWS SOFTWAREThis works just like your favourite software debugger, except that as you single step the code, you can observe the effect on the entire design - including all the electronics external to the microcontroller. Whilst Proteus VSM is already unique in its capability to run near real time simulations of complete micro-controller systems, its real power comes from its ability to perform these simulations in single step mode. With over 750 supported micro-processor variants, many thousands of embedded SPICE models and one the worlds largest libraries of embedded simulation peripherals, Proteus VSM remains the first choice for embedded simulation. It is anything but a simple software simulator since the interaction of all these peripherals with the external circuit is fully modelled down to waveform level and the entire system is therefore simulated. The VSM CPU models fully simulate I/O ports, interrupts, timers, USARTs and all other peripherals present on each supported processor. Its has a text based interface and very efficient commands keeping in line with the unix tradition of short and concise commands that do one thing well. If the program code writes to a port, the logic levels in circuit change accordingly, and if the circuit changes the state of the processor's pins, this will be seen by your program code, just as in real life. gSim51 - 8051 microcontroller simulator gSim51 is a powerful, efficient and cool simulator for 8051 code. It simulates the execution of your object code (machine code), just like a real chip. The micro-controller model sits on the schematic along with the other elements of your product design. Some comments for the Mac port at the end (but it works) Downloading tools SimulIDE : Download the Lin64 AppImage or the Win32. It will be the same thing for Unix-based systems (tested on Ubuntu). Screenshots below were taken from a Windows machine. 8051 SIMULATOR FOR WINDOWS HOW TOThe simulation engine is originally based on the well known DOSBox emulator, which you can make sure of its superiority and high quality to any existing simulator at present time.The most exciting and important feature of Proteus VSM is its ability to simulate the interaction between software running on a microcontroller and any analogue or digital electronics connected to it. The idea behind this tutorial is to show how to install SimulIDE to run codes for an Arduino Uno board. The engine runs in the background and thus is invisible to you,all you see is your Turbo C running Turbo C Simulator uses a refined High-Quality internal filtering system, so that when you run your Turbo C at different resolutions you get the sharpest possible result. 8051 SIMULATOR FOR WINDOWS FULLIf you choose fixed resolution, you can still switch to full screen at any time by pressing Alt-Enter. You can specify at what resolution Turbo C runs, fixed or full screen. Turbo C simulator provides a set of settings which gives you even more control on how Turbo C runs. 8051 SIMULATOR FOR WINDOWS 64 BITIt doesn't make any difference whether you are on a 32 bit or 64 bit version of Windows. Turbo C simulator uses an internal simulation engine which makes it possible to run Turbo C on any versions of Windows, especially Vista and 7, as if it is run in a native environment. By using this software you can install Turbo C, fix any existing installation or configure the way Turbo C runs on your windows machine. The Turbo C Simulator, is the world's first dedicated specifically coded simulator which simulates Borland's Turbo C/ TurboC ++ on any versions of Windows.
