摘要： A technique for designing a logic circuit includes specifying a model. The model including combinatorial blocks, state elements and graphical library elements. The technique maintains a data structure representative of the model, and generates an architectural model and an implementation model from the data structure. The data structure represents a descriptive net list of the model. The architectural model includes C++ code and the implementation model includes Verilog.

摘要： A parallel hardware-based multithreaded processor is described. The processor includes a general purpose processor that coordinates system functions and a plurality of microengines that support multiple hardware threads. The processor also includes a memory control system that has a first memory controller that sorts memory references based on whether the memory references are directed to an even bank or an odd bank of memory and a second memory controller that optimizes memory references based upon whether the memory references are read references or write references.

摘要： A circuit design parameter file is maintained for a circuit being designed by a circuit designer. This circuit design parameter file specifies a physical characteristic of the circuit. A design environment is monitored to detect the addition of a circuitry component to the circuit and a component design parameter file that specifies at least one design parameter for that added circuitry component is accessed. The circuit design parameter file is updated based on the design parameter(s) included in the component design parameter file. The circuit designer is provided with feedback concerning the physical characteristic of the circuit being designed.

摘要： Representing a logic device generally includes creating a model of a logic device, where the model represents a collection of variants of the logic device. A representation of the model may be used in a logic design and a particular variant of the logic device may be selected automatically based on connections made to the representation. Connection errors may be detected automatically and a first indication may be displayed automatically when the connection errors are detected. A second indication that differs from the first indication may be displayed automatically when the connection errors are corrected.

摘要： Logic simulation includes storing a first state to identify in a simulation of a logic design whether a node included in the logic design has a logic high value Logic simulation also includes storing a second state to identify in simulation of the logic design whether the node has a logic low value and storing a third state to identify in simulation of the logic design whether the node has an undefined state. The logic simulation determines an output of the node in simulation of the logic design based on the first state, the second state, and the third state.

摘要： A method of debugging code that executes in a multithreaded processor having microengines includes receiving a journal write command and an identification representing a selected one of the microengines from a remote user interface connected to the processor, pausing program execution in the threads executing in the selected microengine, inserting a journal write command at a current program counter in the selected microengine, resuming program execution in the selected microengine, executing a write to a journal routine if program execution in the selected microengine encounters the journal write command and resuming program execution in the microengine.
