Real Intent Awarded U.S. Patent for Methods and Systems for Correcting X-pessimism in Gate-level Simulation or Emulation

SUNNYVALE, CA, USA — June 7, 2018

– Company’s 7th patent addresses correcting X-pessimism in gate-level verification

Real Intent Inc. has been awarded U.S. patent 9,965,575 for methods and systems for correcting X-pessimism in gate-level simulation or emulation. This 7th patent by Real Intent is directed to its core technology for the functional verification and sign-off of digital logic used in design IP and SoCs. Gate-level netlist simulation treats unknown values (“Xs”) pessimistically, producing results which are not the same as actual hardware and inconsistent with RTL simulation. Netlist sign-off is a key milestone prior to tape-out, and X-pessimism-free analysis is a key requirement for this milestone. Achieving accuracy in gate-level simulation is a major impediment to sign-off, which is Real Intent’s primary focus.

“The award of this 7th patent demonstrates our technology leadership in digital verification, and our ability to innovate as we deliver best-in-class solutions for key problems like X-pessimism,” said Dr. Pranav Ashar, Real Intent’s Chief Technology Officer. “Our customers demand that X-pessimism correction be automatic, work on-the-fly, and deliver the scale and efficiency that makes full-chip gate-level analysis truly viable. Real Intent’s solution ensures that hardware engineers see only the accurate circuit-behavior in verification, delivered via the fastest analysis that saves months of sign-off effort and gives them a key competitive edge.”
