Latest Patents

Selvidge's latest patents include "Compression of Emulation Trace Data" and "Reconstruction Engine for a Hardware Circuit Emulator." The first patent focuses on a system and method for compressing trace data from an emulation system. This involves scan chains receiving trace data from configurable logic blocks within emulation chips, with the capability to compress the data received. Delta compression techniques are utilized, allowing for delta detection functions to be performed by the scan chains or through their outputs. Additionally, event detectors can be integrated within or outside the scan chains, and the compression process may involve receiving multiple data sets and performing compression across their cross-sections.

The second patent, "Reconstruction Engine for a Hardware Circuit Emulator," provides full visibility to each net of a design during modeling. This is achieved by saving states of the design and reconstructing waveforms at each net through logic evaluation using these saved states. In this embodiment, primary data input signals and memory output signals are captured by a logic analyzer and utilized in an emulator to generate state vectors from previously recorded state snapshots. Data compression techniques are applied to reduce storage needs, and parallel evaluation of waveform segments is facilitated, as saved states for the entire period of interest are accessible for reconstruction during logic evaluation.
