Gary,
The underdocumented IP command is one of the most valuable hidden treasures in
MPSIM.

It allows you to set the input stimulus to be TIME or Steps (actually bogon
states).

If add the command "ip time" to your mpsim.ini file, the STI file will be
interpreted as integer microseconds (instead of the default setting of
instruction count, a totally usesless value).

If you then add the command "sc 1" to the ini file, the simulator will accept
stimulus in  cycles (1 microsecond = 1 cycle) and the time column of the output
will be true clock cycles!

The cycle count is accurate except for RTCC fixups (eg. ADDWF RTCC), in which it
is out by one, just like the spec sheets, since it fails to take into account
the fetch/execute skew caused by the instruction cache.
