Proteus VSM for PIC 18
Proteus VSM for PIC18 contains everything you need to develop, test and virtually prototype your embedded system designs based around the Microchip Technologies™ PIC18 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.

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 Limitations
- The External Memory Interface (EMI) of devices such as the PIC18F8X20 is not modelled. These devices can only be modelled when the PMx configuration bits select the Microcontroller Mode (MC) mode of operation. Specifically, the Microprocessor Mode (MP), Microprocessor with Boot Block Mode (MPBB) and Extended Microcontroller Mode (EMC) modes are not supported.
- Power Managed Modes is not modelled. Specifically, the use of IDLEN and SCS/SCSx bits in the OSCCON register to switch oscillator sources and the behaviour of the SLEEP command is not modelled. The SLEEP command always puts the processor in to full sleep mode. This limitation is largely due to poor documentation on how the power managed modes actually affect peripherals.
- Brown-out detection and High-Low Voltage Detect (HLVD) is not modelled.
- The Internal/External Switch Over (IESO configuration bit) and the Fail Safe Clock Monitor (FSCM configuration bit) are not modelled.
- The ECAN module of the PIC18F6680 and PIC18F6685 is not currently modelled.
- The SPP (Streaming Parallel Part) of the USB variants is not currently modelled.
- Isochronous USB transactions in the USB variants is not currently modelled.
- The external programming interface (PGC/PGD pins) 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.
"I use VSM PIC and the IAR C compiler which allows me to run PIC's to emulate all my mechanical devices as my 'test harness' prior to developing the system proper. I estimate that my development time is now 20% of what it was before for any given design, and because of the general flexibility and information views, simulations can be run as a virtual world tests in their harnesses for days at a time and I can minimise the testing when I build in the real world "
