Latest Patents
One of Rachid's latest patents is titled "Method and apparatus for reducing pessimism of graph based static timing analysis." This invention discloses a method that utilizes timing information from multiple inputs to a cell, such as an AND-gate, within an integrated circuit design. The timing information is stored in a timing information register (TIR) linked to an index that identifies the source of the timing information. This method tracks the source of the timing information across a predetermined number of cells, merging the timing information in the TIRs when the index indicates that the information has been tracked sufficiently.
Another notable patent is "Reducing memory used to store totals in static timing analysis." This patent presents a system and method for minimizing memory usage during static timing analysis. It involves storing totals at various points along analyzed paths and utilizing a super-tag mapping table to manage these totals efficiently. The super-tag includes a super-tag ID that references the stored totals and a time delay value, allowing for the reuse of the super-tag ID in other contexts while still maintaining accurate total time delays.
