Real Intent Unveils Major Enhancements in Ascent XV for Early Functional Verification of Digital Designs

SUNNYVALE, CA--(Marketwired - September 19, 2013) - Real Intent, Inc., a leading provider of EDA software products today announced a new release of its Ascent X-Verification System (XV) tool for early functional analysis of digital designs, adding significant enhancements for initialization analysis, and the detection and management of unknown logic values (Xs). All Ascent products find elusive bugs and eliminate sources of uncertainty that are difficult to uncover using traditional RTL simulation, leading to both improved quality of results (QoR) and productivity of design teams.

"Analysis and optimization of design initialization in the presence of X's is a new requirement for SoC sign-off due to modern power-management schemes," said Graham Bell, vice-president of Marketing at Real Intent.  "Ascent XV provides the necessary analysis of initialization sequences to ensure they are complete and optimal for various power states in an SoC.  It provides the same best-in-class verification performance and debug efficiency as our other Ascent products, uncovering issues prior to digital simulation and synthesis."

Ascent XV identifies X-sources and potential X-propagation issues early-on in Verilog RTL or netlist designs. It enables the detection and debug of functional issues caused by X-optimism at RTL, prior to synthesis. It also eliminates unnecessary X's caused by X-pessimism at the netlist. Ascent XV analysis can catch issues prior to RTL sign-off, driving costs down and avoiding monotonous, error-prone debug at the netlist level. Notable features for the new Ascent XV release include:

  • Initialization analysis that reports flops and latches uninitialized after the reset sequence
  • Reset and retention-flop optimization that ensures complete initialization with minimal hardware and routing requirements for savings in area and power
  • Hazard analysis that reports design susceptibility to X-hazards, and automatically detects and reports all X-sources in the design
  • SimPortal that enables Verilog simulation to detect and debug real X-optimism issues, and to model low power retention cells at RTL
  • A debugger that correlates X-optimistic and X-pessimistic signals to X-sources
