This report describes the partially completed correctness proof of
the Viper 'block model'. Viper 7,8,9,11,23] is a microprocessor
designed by W. J. Cullyer, C. Pygott and J. Kershaw at the Royal
Signals and Radar Establishment in Malvern, England, (henceforth
'RSRE') for use in safety-critical applications such as civil
aviation and nuclear power plant control. It is currently finding
uses in areas such as the de ployment of weapons from tactical
aircraft. To support safety-critical applications, Viper has a
particulary simple design about which it is relatively easy to
reason using current techniques and models. The designers, who
deserve much credit for the promotion of formal methods, intended
from the start that Viper be formally verified. Their idea was to
model Viper in a sequence of decreasingly abstract levels, each of
which concentrated on some aspect ofthe design, such as the flow
ofcontrol, the processingofinstructions, and so on. That is, each
model would be a specification of the next (less abstract) model,
and an implementation of the previous model (if any). The
verification effort would then be simplified by being structured
according to the sequence of abstraction levels. These models (or
levels) of description were characterized by the design team. The
first two levels, and part of the third, were written by them in a
logical language amenable to reasoning and proof."
