  • Publication number: 20130054854
    Abstract: The present invention presents an effective Cycle-count Accurate Transaction level (CCA-TLM) full bus modeling and simulation technique. Using the two-phase arbiter and master-slave models, an FSM-based Composite Master-Slave-pair and Arbiter Transaction (CMSAT) model is proposed for efficient and accurate dynamic simulations. This approach is particularly effective for bus architecture exploration and contention analysis of complex Multi-Processor System-on-Chip (MPSoC) designs.

  • Publication number: 20120185231
    Abstract: The present invention discloses a cycle-count-accurate (CCA) processor modeling, which can achieve high simulation speeds while maintaining timing accuracy of the system simulation. The CCA processor modeling includes a pipeline subsystem model and a cache subsystem model with accurate cycle with accurate cycle count information and guarantees accurate timing and functional behaviors on processor interface. The CCA processor modeling further includes a branch predictor and a bus interface (BIF) to predict the branch of pipeline execution behavior (PEB) and to simulate the data accesses between the processor and the external components via an external bus, respectively. The experimental results show that the CCA processor modeling performs 50 times faster than the corresponding Cycle-accurate (CA) model while providing the same cycle count information as the target RTL model.

  • Patent number: 6314379
    Abstract: An integrated defect yield management and query system for a semiconductor wafer fabrication process is disclosed. A local area network connects various testing devices for testing defect conditions of wafers, a defect yield management server and a client device. After inspection, these devices generate a plurality of process records corresponding to each of the semiconductor wafers. The defect yield management server retrieves the process records through the local area network. These process records are stored in a database divided into a plurality of fields, wherein each field corresponds to a specific defect property of the semiconductor wafers. Therefore, these acquired on-line data and their related history records can be accessed by using an inquiring interface, and the client device can effectively poll the process records stored in the database of the defect yield management server.

  • Patent number: 6020234
    Abstract: A method is disclosed for increasing the capacitance of high-density DRAM devices by microlithographic patterning. A semiconductor substrate having a MOS transistor comprising a gate and source/drain regions, and a word line and a bit line is provided. A layer of inter-poly oxide is deposited over the substrate and planarized. Contact holes are etched in the oxide layer until the substrate is exposed. A layer of photoresist is next blanket deposited over the substrate. Using microlithographic methods, the photoresist is then patterned with in-line or staggered micron size features and the underlying inter-poly oxide layer is etched using the photoresist as a mask. The resulting inter-poly oxide surface, therefore, acquires the shape of a micro-folded topography having a roughened surface area of many folds larger than the original flat surface.
