High Level Synthesis: from Algorithm to Digital Circuit- P11

High Level Synthesis: from Algorithm to Digital Circuit- P11: This book presents an excellent collection of contributions addressing different aspects of high-level synthesis from both industry and academia. "High-Level Synthesis: from Algorithm to Digital Circuit" should be on each designer's and CAD developer's shelf, as well as on those of project managers who will soon embrace high level design and synthesis for all aspects of digital system design. | 86 M. Meredith bind c Note that the addition of these functions allows the binding to be done using the conventional SystemC port binding syntax socket.bind channel or socket channel Also note that the binding functions are defined as templates. This lets the same ports and binding functions to be used for port-to-port binding in a hierarchical design. 5.6 Structural Hierarchy In addition to the process control constructs SystemC synthesis supports the SystemC constructs for construction of structural hierarchies. An engineering team can attack a large design problem using structural decomposition breaking the problem down into multiple smaller modules that communicate through user-defined interfaces. Individual sub-modules can be assigned to different team members if desired supporting a conventional team structure and concurrent design approach. Each module can contain any number of cooperating SC-CTHREADs SC_METHODs and sub-modules. Communication between modules is achieved using a port-to-signal binding mechanism of a kind that is familiar to RTL designers or even designers using schematics. Here is an example of a hierarchical design using modular interfaces as described previously.

The complete structural hierarchy can be simulated at a behavioral level accurately .
