I haven't seen one.  But it would certainly make sense to tie in a GDB remote protocol server, hooked to the breakpoint facility of the SIMH emulation for machines that have one.

One drawback is that there aren't all that many SIMH architectures that have GDB support.  VAX does, and Alpha; that's about it.  I don't know how hard it is to do a basic platform in GDB, probably not all that difficult.  At least for machines like PDP-11.  One's complement might be harder (PDP-1), never mind things like the IBM 1620...  :-)
