7  Synopsis    [Combinational verification by residue arithmetic.]

9  Description [This package implements residue verification between two
10  networks. The method used is based on residue arithmetic and the
11  Chinese Remainder theorem. Verification is performed by interpreting
12  the outputs of the circuits as integers and verifying the residues
13  of the outputs with respect to a set of moduli. The choice of moduli
14  is directed by the Chinese Remainder Theorem in order to prove
15  equivalence of the two circuits. This method works well with
16  multipliers and possibly other arithmetic circuits (due to its
17  dependence on residue arithmetic).  Discretion should be exercised
18  in applying this method to general combinational circuits. Residue
19  verification is provided with vis-cu ONLY. It reads both blif and
20  blif-mv files. However, it does NOT support multi-valued
21  variables. Residue verification is primarily for combinational
22  verification, but may be applied to sequential circuits with the
23  same state encoding. The latch outputs are then considered to be
24  combinational inputs of the circuits and the latch inputs and reset
25  are considered to be combinational outputs of the circuits. This
26  package provides some combinational verification also. Some/all of
27  the outputs of the circuit may be verified directly (without using
28  residues). In using both direct and residue verification,
29  verification of arithmetic circuits may become easier. ]
