The invention provides a distributed
data path combination equivalence
verification method and a distributed
server, and the method comprises the steps: carrying out the
rewriting of two to-be-verified
data path circuits, and obtaining two circuit description files with similar circuit structures; constructing a Miter circuit according to the circuit description file;
random logic simulation is carried out on the Miter circuit to obtain internal potential equivalent nodes, and the internal potential equivalent nodes are stored in an equivalent node
queue; selecting potential equivalent node pairs from the equivalent node
queue, extracting fan-in cones of the potential equivalent node pairs, and constructing a sub miter circuit according to two groups of fan-in cones; selecting a
verification mode according to the density degree of the XOR block in the sub-miter circuit, and verifying the sub-miter circuit; if
verification succeeds, the corresponding potential equivalent nodes and the corresponding fan-in cones are combined, otherwise, other potential equivalent node pairs continue to be verified until verification of all potential equivalent nodes is completed; and the SAT
solver is used for executing final equivalence verification and returning a verification result, so that the equivalence verification of the
data path combination is efficiently realized.
