Hi Xianfeng,
I have never found any detailed documentation on Or1ksim. There are the
various README files in the source. You can use the "help" option in
Or1ksim to get a brief explanation of its arguments and commands.
Or1ksim is only partly complete (the last stable build was 0.2.0 from
2004). The code base shows it was in a migration to a more general
structure that could dynamically configure the architecture, but this
work is not finished.
I had to learn about Or1ksim by reading the code. You may get a little
more feel for it by looking at my application note on building a SystemC
wrapper for Or1ksim.

One approach you may like to consider is to add additional peripherals
via this SystemC interface. If you wish to modify Or1ksim itself, then I
suggest you look at one of the existing peripherals (see the peripheral
subdirectory), such as the 16450 UART.
If you are successful, then please contribute your code back. We're
particularly interested in any bugs you find. You can record them via
the OpenRISC tracker:
http://www.opencores.org/ptracker.cgi/list/or1k
If you find time to add some documentation, that will be really helpful
for everyone.
Best wishes,
Jeremy
