silab is their development board with jtag for about 70$.
but, how usefull jtag is?

jtag is usefull, because you test using the real silicon, in the
real world. In any interaction with peripherals/pins, that can
be vitally important :)

Simulators are good with the opcodes/core, but struggle with
the peripherals.

can I get the same result with software simulator?

You can certainly learn a lot with a simulator.

I'd suggest starting with the SiLabs ToolStick, ~$10, which has a small uC inside, and a USB Debug/Pgm link.
Gives the best of both worlds : Cheap, but uses real silicon :)


If you move up in their families, the C8051F41x is the newest.
This has 12bit ADC/DAC, and an on chip from-5V regulator,
so can drive power mosfets directly.

Atmel's newest AT89LP series members, have on-chip-debug, and
Atmel's debug solution is comming.
