PIC Instruction Set Simulators

Verocel, Inc., known for supplying certification evidence for operating systems hosted on major microprocessor lines suchas the PowerPC™ and Intel® x86,has expanded its offerings to support certification of software on the Microchip PIC® family of microcontrollers. The Verocel PICSIM™ PIC instruction-level simulator software gives test developers a means to write tests in the Microsoft® Windows® environment that can directly test PIC-based applications.


Test developers create requirements-based tests written in the C programming language and the Verocel PICSIM is linked as a library. The program-under-test is loaded into the Verocel PICSIM and executed under the control of the test. Test developers can directly call functions in the software-under-test, monitor all memory accesses (reads and writes), alter data fetched or stored dynamically, and collect structural coverage data during testing. The software-under-test need not be altered.
Verocel has successfully completed several certification efforts with this system. The Verocel PICSIM software currently supports the PIC18F4321, PIC18F442, PIC18F8720, PIC18F6622, PIC18F4520, and PIC18F8722 microcontrollers.

Other processors within the PIC18 microcontroller family will be added to the suite soon. If your preferred processor is not listed above, contact Verocel to have it added.
