I, too, as a guy new to the ARM7, would find it helpful
to 'simulate' code well before putting it on hardware.

I have the gnuarm and eclipse with the Olimex board and
wiggler.

But, I have found that after many many years writing
assembly code (AVR now), that the simulator is invaluable in
new, tricky, routines.

On another subject...
What jtag and IDE for less than $3000 gives me the ability to
know real time execution elapsed time?

Thanks,

Glen

I would recommend IAR.  They offer pipeline accurate simulation.  When
requesting a quote, be sure to ask about the different product options.

I forgot to mention the Kickstart edition is free, and limited to 32k code
size.  Just fill out the info for free download:

Rowley CrossWorks for ARM.

Same with Keil:
http://www.keil.com/arm/Default.asp?bhcp=1

One major difference between Keil and all other simulators. Keil can
simulate the whole LPC2xxx chip while other simulators simulate the
ARM core. 
So what's the difference. You can simulate a timer, incoming results
from an ADC... with the Keil simulator but not with the others.
If you want to debug tricky algorithms any of the instruction set
simulators should do well, if peripheral simulation is desired, the
only one I know is Keil.

The 16k version to check it out is free.

Glen,

Simulation is good, but for actual, real-time timing analysis there
is nothing better than an emulator with trace. Trace was something
that was common on 8 & 16-bit MCUs, but for some reason is 
overlooked on many 32-bit devices.
Luckily, most Philips LPC2xxx devices have the ETM trace port, 
so you can get a JTAGjet-Trace to get actual timing of any interrupt
or event, elapsed time of a function, as well as other useful trace 
features for about $3,500. 
BTW - this is  how much you will have to pay for a good simulator
anyway.

Glen,

if you want to do execution time measurements, you need a tool with
real-time trace and time stamp. Our BICEPS emulator is able to calculate
time differences (for example elapsed time of interrupt routines). This
is better than to simulate it and the tool price is within your budget
(see www.arm-emulator.com/products/facts.html
<http://www.arm-emulator.com/products/facts.html> ).

Regards

Martin

Lauterbach ICD is a very useful tool. The costs are about 2000Euro
