摘要:
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.

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.

A halogen-free varnish includes (A) resin, (B) curing agent, (C) flame inhibitor (flame-retarding agent), (D) accelerator and (E) additives. Resin of (A) has novolac epoxy resin, DOPO-CNE and DOPO-HQ-CNE. Curing agent of (B) includes Benzoxazine resin and phenol novolac resin. Glass fabric cloth is dipped into the halogen-free varnish so as to form a prepreg with better thermal stability, anti-flammability, low absorbent ability and higher curing rate. Furthermore, the prepreg has more toughness.

A resin composition contains a solvent and a solid content dispersed in the solvent. The solid content does not contain phenolic resin. The solid content contains a benzoxazine resin and a phosphorus-containing epoxy resin. The weight ratio of the benzoxazine resin to phosphorus-containing epoxy resin is about 0.6:1 to about 3.0:1. A circuit board substrate and a copper clad laminate fabricated with the resin composition mentioned above are disclosed too.

The present invention discloses a method for fabricating a carbon membrane having pore regularity. The method comprises: providing a template having a plurality of pores arranged regularly; performing a tubular carbon forming process in the regularly-arranged pores; then performing a removal process to form an annular cavity; performing a carbon forming process in the annular cavity to combine the carbon in the annular cavity with the tubular carbon to thereby form a carbon substance having a thick wall; and repeatedly performing the removal process and the carbon forming process so as to form a carbon membrane having pore regularity.

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.
