trying to simulation a custom ASIC with embedded MIPS processsor.
.text 0xBFC00000 results in errors. Claims invalid address for instruction. Is there a way to configure the simulator to accept this? configurable address space.

If you want to put the text segment somewhere besides 0, then you will need to recompile spim/qtspim. The base and size of the segments is defined in CPU/mem.h. I believe you can change them and recompile and it should work, but I can't say that I remember testing arbitrary configurations. Please be careful not to overlap them however.
