3. Port mismatch between Timing model & behavioral code: There are models which have timing information of the block in any hierarchical design. In complex SOC, advance synthesis approach is followed in which the synthesis of the blocks is done separately. But there can be some interaction betwe...
In this section, we describe the proposed hardware task migration scheme for heterogeneous FPGA clusters. First, we present the proposed structure of such clusters. Second, we explain the timing diagram of our proposed scheme. Finally, we discuss the memory footprint of our scheme. CPRflatten: ...

Encoding controller 426 controls the sequencing (e.g, timing) and operating of the constituent elements of the encoding side of system 400, including the application of signals (e.g., multiplexing) to and from such elements. Controller 426 is connected to DRAM 402 by an address and control ...

In a multi-wide class design layout, design rule checks for enclosure of multi wide class objects prevent false errors or false passes by performing such checks against the non-virtual boundaries of a wide class object, and not against the virtual boundaries. An exemplary embodiment provides a ...
For example, the critical timing path delay may be increased with each doubling of the data width (and consequent doubling of area). Since the computed result may be fed back to compute the next value, the doub
