3rd party HC11

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.

Product Summary

Proteus VSM for HC11 Includes:

  • A full professional licence of the ISIS Schematic Capture package, allowing you to create your own schematics for simulation.
  • A full licence for the interactive VSM simulation engine, enabling you to both simulate and interact with your entire system prior to prototyping.
  • Ability to fully simulate HC11 variants in your own schematics
  • Thousands of standard peripheral models and embedded peripheral models are available for the simulation of your own projects.
  • Measurement and analysis with over a dozen industrial grade virtual instruments (DSO, Logic Analyser, I2C Protocol Analyser, etc.)
  • System wide diagnostics allowing you to receive detailed trace messaging on components of your choice and/or the system as a whole during simulation.
  • Full debugging capabilities either via Proteus VSM's internal system, through direct integration with the MPLAB environment or via other supported compilers.

Purchasing Options

Proteus VSM for HC11 is the full professional family and includes all currently supported HC11 variants (see below).

Analysis capabilities can be upgraded to include Graph Based Simulation via the Advanced Simulation Options module.

For a truly complete design solution schematics can be netlisted to one of our integrated PCB Design products for physical board layout.

Supported Variants

Currently modelled HC11 Variant Set:

  • MC68HC11A8
  • MC68HC11E9

Supported Features

Proteus VSM simulates all the features of the real device including:

  • 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.

Unique Productivity Enhancements with Proteus VSM for HC11:

  • 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.

Supported Compilers

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.
