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.

Product Summary

Proteus VSM for 8051 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 8051 variants in your own schematics - 8051 Starter Kit option enables only the generic 80C51 variant.
• 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

The 8051 Starter Kit is the entry level purchase and includes the 80C51 variant only.

Proteus VSM for 8051 is the full professional family and includes all currently supported 8051 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.

Please see the commercial price list for pricing information or contact us to further discuss requirements.

Supported Variants

Currently modelled 8051 Variant Set:

• Generic 80C31, 80C32, 80C51, 80C52, 80C54 and 80C58.
• AT89C51, AT89C52 and AT89C55.
• AT89C51RB2, AT89C51RC2 and AT89C51RD2
• P87C51FA, P87C51FB, P87C51FC
• P87C51RA+, P87C51RB+, P87C51RC+, P87C51RD+

Supported Features

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

• 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.

Unique Productivity Enhancements with Proteus VSM for 8051:

• 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.

Main Limitations:

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

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.
