The applets in this chapter demonstrate various example circuits based on the PIC16C84 or PIC16F84 8-bit microcontrollers from Arizona Microchip. Hades provides a complete hardware-software cosimulation environment including system-level components like serial (RS232) communication and text-mode or graphical displays. The simulator performance can reach 500.000 instructions per second, which allows running the simulation at real-time or at near real-time with full interactive control.

We selected the 16C84 microcontroller as the first microprocessor in Hades for several reasons:

• small and regular instruction set
• low cost
• DIP18 package
• EEPROM/FLASH based, therefore easy (re-) programmable
• several low-cost DIY programmers available
• good software support (e.g. MPLAB, picclite)
