摘要： Performance of an integrated circuit design, whether embodied as a design encoding or as a fabricated integrated circuit, can be improved by selectively substituting low Vt transistors in a way that prioritizes substitution opportunities based on multi-path timing analysis and evaluates such opportunities based on one or more substitution constraints. By valuing, in a prioritization of substitution opportunities, contributions for all or substantially all timing paths through the substitution opportunity that violate a max-time constraint, repeated passes through a timing analysis phase can be advantageously avoided or limited. In addition, by recognizing one or more constraints on actual low Vt substitutions, particular noise-oriented constraints, the scope of post substitution design analysis can be greatly reduced. In some realizations, substitutions are performed so long as a leakage current budget is not expended. As a result, integrated circuit designs prepared in accordance with the described techniques may exhibit substantial cycle time improvements through judicious selection of gate instances for substitution. In some realizations, improved yields of high grade parts may result.

摘要： A method for determining flop circuit types includes performing a layout of an IC design including arranging master and slave latches of each of a plurality of flops to receive first and second clock signals, respectively. The initial IC design may then be implemented (e.g., on a silicon substrate). After implementation, the IC may be operated in first and second modes. In the first mode, the master latch of each flop is coupled to receive a first clock signal. In the second mode, the first clock signal is inhibited and the master latch is held transparent. The slave latch of each flop operates according to a second clock signal in both the first and second modes. The method further includes determining, for each flop, whether that flop is to operate as a master-slave flip-flop or as a pulse flop in a subsequent revision of the IC.
