STRUCTURE

SYNOPSIS
Expands sub-components of a hardware description using their definitions.
LIBRARY
unwind
DESCRIPTION
UNFOLD_CONV thl "t1 /\ ... /\ tn" returns a theorem of the form: 
   B |- t1 /\ ... /\ tn = t1' /\ ... /\ tn'
where each ti' is the result of rewriting ti with the theorems in thl. The set of assumptions B is the union of the instantiated assumptions of the theorems used for rewriting. If none of the rewrites are applicable to a ti, it is unchanged.
FAILURE
Never fails.
EXAMPLE
#UNFOLD_CONV [ASSUME "!in out. INV (in,out) = !(t:num). out t = ~(in t)"]
# "INV (l1,l2) /\ INV (l2,l3) /\ (!(t:num). l1 t = l2 (t-1) \/ l3 (t-1))";;
. |- INV(l1,l2) /\ INV(l2,l3) /\ (!t. l1 t = l2(t - 1) \/ l3(t - 1)) =
     (!t. l2 t = ~l1 t) /\
     (!t. l3 t = ~l2 t) /\
     (!t. l1 t = l2(t - 1) \/ l3(t - 1))
