This part is not necessary.  You could reuse the existing
sim-sched-sim instance - just use a new unused client number.
(If were to use a new scheduler instance, you would have to
connect its upstream "advance" pin to an appropriate source.)

All correct, I'm impressed!

I am sorry, but I'm not familiar with that low-level aspect
of eCos.  I suspect choosing a lower interrupt number would
help, as might putting breakpoints into eCos functions for
setting interrupt masks and dispatching received interrupts.
If you suspect a sid (rather than eCos) problem, consider
monitoring the interrupt controller with tksm, and manually
sending interrupts from the pin view.

This suggests that you should be using the an arm-cpu
configuration for sid that includes models for selected
peripherals of the pid board, like the sid/pregen/arm-pid.conf
file.  Sending a diff between that file and your modified
version would help diagnose problems in the future.
