Systems and methods for solving finite element models, wherein the matrix that governs the solution is modified by adjusting the weighting coefficients of the matrix so that the elements which lie on the diagonal of the matrix are non-negative and the elements which are off the diagonal are non-positive. In one embodiment, a system is discretized on a finite element mesh with the contribution of each node to the discretization being weighted based upon the direction of fluid flow across each element. The nodes which are upstream from the other nodes of the respective elements are weighted more heavily to cause the resulting matrix to be substantially diagonal. This matrix is solved using traditional techniques.

A computer implemented representation of a circuit design including memory is abstracted to a smaller netlist by replacing memory with substitute nodes representing selected slots in the memory, segmenting word level nodes, including one or more of the substitute nodes, in the netlist into segmented nodes, finding reduced safe sizes for the segmented nodes and generating an updated data structure representing the circuit design using the reduced safe sizes of the segmented nodes. The correctness of such systems can require reasoning about a much smaller number of memory entries and using nodes having smaller bit widths than exist in the circuit design. As a result, the computational complexity of the verification problem is substantially reduced.
