A representation of an initial design domain, at least one subtractive tool assembly, machine degrees of freedom, and a termination criterion are used to iteratively generate intermediate part designs by redistributing the material within the design domain. A measure of inaccessibility of exteriors of the intermediate part designs by the at least one subtractive manufacturing tool assembly are generated. The measure of inaccessibility is used to inform generation of an intermediate part design at a next iteration. The iterative algorithm is terminated when the termination criterion is satisfied, the result of the iterative algorithm being a part design accessible for subtractive manufacturing.

A computer-implemented method, computer program, system and apparatus for computing a thermal thickness and providing pre-manufacturing feedback on a design of a three-dimensional physical object that is to be formed by solidification of a fluid in a mold. An equation is solved, representing heat release through the cavity-mold interface when the object is formed. The thermal thickness and its uniformity provide insight in the manufacturability of the object, and may be used to automatically generate pre-manufacturing feedback. The thermal thickness and pre-manufacturing feedback are transmitted or displayed to a user.

The independent claims of this patent signify a concise description of embodiments. An emulation control block enables a user to view an entire design in the same phase so that the used can observe and control a halted design in the same logical reference cycle. Both the clock cone and design flops are provided in the state which occurs after the evaluation of cycle K of the reference time. During cycle K+1 of an emulation, the values of derived clocks for cycle K+1 are computed. Moreover, during cycle K+1 of the emulation, the values of the sequential elements are computed based cycle K values of the clocks. When the emulation is halted due to a break, the clock cone is reverted to its previous state. This Abstract is not intended to limit the scope of the claims.

Methods for iteratively optimizing a two-dimensioned tiled area such as a lithographic mask include determining a halo area around each tile in the tiled area. An extended tile is made of a tile and a halo area. Each extended tile in the tiled area is iterated until a criterion is satisfied or a maximum number of iterations is met. Optimizing the extended tile produces a pattern for the tile such that at a perimeter of the tile, the pattern matches adjacent patterns that are calculated at perimeters of adjacent tiles.
