The present invention is a method and system for outputting a sequence of commands and data described by a flowchart. The method includes steps as follows. A flowchart describing a sequence of commands and data is received. The flowchart includes a plurality of flowchart symbols. Each of the plurality of flowchart symbols is assigned a ROM (read only memory) record. Assigned ROM records are stored in a ROM. A processor is generated to include the ROM, wherein the processor receives as input a CLOCK signal, a RESET signal, an ENABLE signal and N binary inputs x1, x2, . . . xN, and outputs the sequence of commands and data.

Objects are assigned to points in a rectangle by dividing the rectangle is divided into a plurality of smaller rectangles and applying an object assignment procedure, such as Kuhn's algorithm, to initially assigned objects in each second rectangle. The initial assignment is performed by calculating a maximal cost of assignment of objects to points, and selecting an assignment of objects having a minimum value of maximal cost, identified by iteratively recalculating the maximal matching assignment based on a midpoint of between the minimum and maximum costs.

A method of analyzing multimode delay in an integrated circuit design to produce a timing model for the integrated circuit design, by inputting a net list, IO arc delays, interconnection arc delays, and constant nets with assigned Boolean functions for the integrated circuit design, propagating the constant nets and assigning Boolean conditions to the IO arc delays and the interconnection arc delays, evaluating timing path delays and conditions for the integrated circuit design, creating the integrated circuit design timing model parameters, and outputting the integrated circuit design timing model. The method is especially desirable for netlists with very complicated mixing logics that include muxing of clocks. In particular, RRAMs are such netlists.

The present invention provides a method of verification of a RRAM tiling netlist. The method may include steps as follows. Properties “memory_number”, “clock_number” and “netlist_part” of all nets and cells of a RRAM tiling netlist are set to a value 0. A boolean function 0 is assigned to all ground nets of the RRAM tiling netlist, and a boolean function 1 is assigned to all power nets of the RRAM tiling netlist. The RRAM tiling netlist is verified for each customer memory Memk, k=1, 2, . . . , N.

The present invention is a method and system for outputting a sequence of commands and data described by a flowchart. In an exemplary aspect of the present invention, a method for outputting a sequence of commands and data described by a flowchart includes steps as follows. A flowchart describing a sequence of commands and data is received. The flowchart includes a plurality of flowchart symbols. Each of the plurality of flowchart symbols is assigned a ROM (read only memory) record. Assigned ROM records are stored in a ROM. A module (e.g., a CKD, or the like) is generated to include the ROM, wherein the module receives as input a CLOCK signal, a RESET signal, an ENABLE signal and N binary inputs x1, x2, . . . xN, and outputs the sequence of commands and data.

A user-defined memory design is mapped to memories of a base platform for an IC that contains a plurality of memory sets, each containing a plurality of memories of a predetermined type. An optimal memory set is selected from the plurality of memory sets for the design by selecting a preference rate for each memory set from the plurality of sets based on the design and its connections to portions of the IC, and selectively assigning the design to one of the memory sets based on the preference rate. The design is optimally mapped to a plurality of memories of the selected memory set by defining an index of the position of each customer memory in the selected memory set. The customer memories in the selected memory set are arranged in an order, and successive numbers of memories of the selected memory set are assigned to each customer memory in order.

The present invention is a method and apparatus for optimizing the design of a combinational circuit. The method includes constructing a circuit sheaf for the combinational circuit and then performing vector optimization with domination. In the preferred embodiment, a complete BDD B is determined and, from that, a list of F-sets is computed. If the combinational circuit includes cells other than NOT, AND and XOR cells, the circuit is first transformed such that it only has those types of cells.

A via-configurable circuit block may contain chains of p-type and n-type transistors that may or may not be interconnected by means of configurable vias. Configurable vias may also be used to connect various transistor terminals to a ground line, a power line and/or to various terminals that may provide connections outside of the circuit block.

A method of configuring a random access memory matrix containing partially configured memories in the matrix. The method includes the steps of independently calculating a memory enable signal and a configuration signal for a partially configured memory in each memory tile of the memory matrix. Memory tiles not supported by a memory compiler are determined. A memory wrapper is provided for each tile not supported by the memory compiler. An address controller is inserted in the memory matrix for each tile in a group of tiles. Output signals from each memory location in a memory group having a common group index are combined into a single output signal. A first stripe of memory tiles containing non-configured memory having a first width is selected. A second strip of memory tiles containing configured memory having a second width is also selected.
