TSIM simulation time overflow

[Sven-Åke Andersson]

I am trying to load my Linux image and simulate it using TSIM. Here is what
happens.
I get a simulation time overflow. I am using the SP605 board.

TSIM evaluation version is limited to 32-bit time, roughly
equal to 1 minutes real-time @ 50 MHz. However, this is no
your problem - the real issue is that you are trying to run
linux with only 4 Mbyte SRAM, this will obviously not work.
Try this command line instead:

tsim-leon3 -nosram -sdram 32 -mmu images/image.dsu

the linux prompt and then stopped with Simulation time overflow

Looks good to me. Once you get to the promt, the linux kernel
might invoke the power-saving functions in the processor,
accelerating the simulation speed significantly. The eval
version of TSIM will then time-out pretty quick ...
