Abstract:
An integrated circuit having a parent terrain (20) and a hierarchal order of nested voltage islands (22) within the parent terrain. Each of the higher-order voltage island (e.g. 24) are nested within a tower-order voltage island (e.g. 22) and have the same hierarchal structure.
Abstract:
Methods, systems and program products for evaluating an IC chip (130, 200) are disclosed. In one embodiment, the method includes running a statistical static timing analysis (SSTA) of a full IC chip design (132); creating at-functional-speed test (AFST) robust paths (156) for an IC chip (130, 200), the created robust paths (156) representing a non-comprehensive list of AFST robust paths (156) for the IC chip (130, 200); and re-running the SSTA with the SSTA delay model setup (152) based on the created robust paths (156). A process coverage is calculated for evaluation from the SSTA runnings; and a particular IC chip (130, 200) is evaluated based on the process coverage.
Abstract:
An integrated circuit comprising: a parent terrain (element 12); and a hierarchal order of nested voltage islands within the parent terrain (element 12), each higher-order voltage island nested (Figure 5, element 32) within a lower-order voltage island (Figure 5), each nested voltage island (Figure 5, element 32) having the same hierarchal structure.
