In complex SOC, advance synthesis approach is followed in which the synthesis of the blocks is done separately. But there can be some interaction between the rest of the design and these synthesized blocks. So, the paths between them need to be timed. Timing model (PTM) provides such timing...
In the Split-Row algorithm, row processing is partitioned into two blocks, where the row processing in each partition is performed using only the input messages contained within its own partition, plus one cross-partition sign bit. This stands in contrast to standard decoding where row processing...
It is important to mention that the computer software is working on GDSII and GDSIII Stream format database (industry standard IC layout representation database) which covers all the commercial layout editors in the VLSI field today. Previous Patent: Source synchronous timing extraction, cyclization ...
Furthermore, the size of the LUT has an impact on the timing and thus, limits the speed of the processor and may be prone to implementation errors.The illustrative embodiments take advantage of the mathematical properties of the LUT in order to provide the same result as a fully filled LUT...
such as required functionality and timing, at step82. The requirements of the design are implemented, for example, as a netlist or electronic circuit description, at step84. The implementation can be performed by, for example, schematic capture (drawing the design with a computer aided design to...
