Hi !

In the case of PICs, you can use the debugger tools (ICD - In Circuit Debugger and ICD2) to run a circuit in real time e check what is happening inside the uC, as checking the registers contents, ports changes, count cycles, insert breakpoints, etc.
It is very useful to find mistakes and bugs in the program (firmware) and to optimize the code written. The downside os that with PICs, you lose some ports (pins) and a part of memory and RAM, and only the new types have this capabilities (of debugging).
