  • Patent number: 9875329
    Abstract: A host system for transferring data to a target system is provided. The host system may include a layout database for storing mask layout data representing an integrated circuit (IC) in terms of planar geometric shapes. The hosts system may further include a processor configured to import the mask layout data from the layout database to a memory-mapped disk in the host system. The processor is further configured to translate the mask layout data into one or more cell views according to a table hierarchy in the memory-mapped disk. The processor is further configured to transmit the one or more cell views from the memory-mapped disk to a magnetic disk of the target system.

  • Patent number: 8739087
    Abstract: In the process of designing an integrated circuit (IC), it is often the case that a functional description is converted into multiplexers. In some cases it would be more efficient to combine two or more multiplexers into a larger multiplexer to identify potential design problems in the original register transfer level (RTL). Such early detection can prevent routing congestion problem that would be too expensive to fix later. A large multiplexer is defined as a multiplexer having a number of inputs and control signals that is above a predetermined threshold. When such a multiplexing functionality is detected that function may be replaced in the circuit with a large multiplexer that would be a more efficient implementation. Accordingly the circuit is checked for existence of multiplexing functions, and merging, when possible, of such multiplexing functions to achieve the ability to instantiate the multiplexing functionality with a large multiplexer.
