  • Proteus VSM for HC11

    Proteus VSM for HC11 contains everything you need to develop, test and virtually prototype your embedded system designs based around the popular HC11 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.

    Technical Information

    HC11 Variants

    • MC68HC11A8
    • MC68HC11E9

    Model Features

    • Models both the single chip and the expanded modes.
    • Supports all port and other I/O pin operations.
    • All on-chip peripherals including the capture timers, COP, pulse accumulator, ADC, SPI and SCI
    • EEPROM operation including minimum write timing and data persistence between simulation runs.
    • Program and external memory can be simulated internally to the model for maximum throughput, or externally in order to validate the hardware design.
    • All interrupt modes are supported.
    • Internally generated processor clock for performance. Event timing accurate to one clock period.
    • In expanded mode, the model can be set to exercise the E and AS pins only when accessing external addresses. This significantly improves simulation performance.
    • 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.

    Model Limitations

    • No significant functional limitations at this time.

    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.
