  • Proteus VSM for 8051

    Proteus VSM for 8051 contains everything you need to develop, test and virtually prototype your embedded system designs based around the popular 8051 series of microcontrollers. The unique nature of schematic based microcontroller simulation with Proteus facilitates rapid, flexible and parallel development of both the system hardware and the system firmware. This design synergy allows engineers to evolve their projects more quickly, empowering them with the flexibility to make hardware or firmware changes at will and reducing the time to market. Proteus VSM is discussed in more detail here.

    Purchasing Options

    Each purchase of the Proteus VSM products includes a professional copy of the ISIS schematic capture package, the VSM simulation engine with industrial grade virtual instrumentation and literally thousands of embedded peripheral models (Nytt vindu). The system can be further upgraded by adding graph based simulation and PCB layout modules.

    If you wish to add PCB Layout or other processor families to your purchase please visit the commercial price list or contact us to further discuss requirements.

    Model Features

    • The entire instruction set and SFR's.
    • Supports all port and other I/O pin operations.
    • All on-chip peripherals including timers and UART in all modes of operation (see limitations).
    • All interrupt modes.
    • Internally generated processor clock for performance. Event timing accurate to one clock period.
    • Provides internal consistency checks on code (e.g. execution of invalid op-codes, illegal memory accesses, stack overflow checking, etc.).
    • more... Fully integrated in to the VSM source level debugging system.
    • more... Fully integrated into the Proteus Diagnostic Control System.

    Model Limitations

    • The X2, SPI and keyboard interrupt mode of the AT89C51Rx2 Variants are not modelled.

    Compiler support

    Proteus VSM models will fundamentally work with the exact same HEX file as you would program the physical device with. However, far more debugging information is available when using a compiler to write the firmware and providing these object files to Proteus in place of the HEX file provides a much richer working environment. More information on supported compilers can be found here.
