Real Intent Delivers Major Innovation in Clock Domain Crossing Sign-Off of SoC Designs

New Meridian Physical CDC Brings Giga-Scale Capacity and Enhanced Analysis to Gate-Level Designs

SUNNYVALE, CA--(Marketwired - May 21, 2015) - Real Intent, Inc., a leading provider of SoC and FPGA sign-off verification solutions, today announced Meridian Physical CDC – a new tool that offers the industry’s first and comprehensive way to debug clock domain crossing violations at the gate level of digital designs. Complementing Real Intent’s Meridian CDC solution that provides comprehensive analysis for RTL sign-off, Meridian Physical CDC maintains Real Intent’s product leadership in delivering the industry’s fastest-performance, highest-capacity and most precise CDC solutions in the market.

Meridian Physical CDC targets the post-synthesis stage of SoC design at the gate level, where implementation tools can introduce changes that might cause unintended signal glitches and functional failures. It addresses various failures including glitching on control signals, clock networks and data signal paths, and incorrect optimization of clock synchronizer logic.

Ramesh Dewangan, vice president of product strategy at Real Intent, said, “CDC verification traditionally has been targeted at RTL sign-off before physical implementation begins. The CDC problems introduced during synthesis along with the addition of test logic and low-power optimizations are risk factors that have not been covered adequately until now. Our new physical CDC software solution extends CDC sign-off to the implementation stage. With the largest flat capacity of any tool in the industry, Meridian Physical CDC provides verification without sacrificing precision. It ensures a glitch-free implementation for all signal crossings, using the widest set of checks and the latest static analysis engines, including our new high-performance formal engines. Now implementation engineers can be confident the designs they are handing off to tape-out are free of CDC bugs.”

Meridian Physical CDC also includes iDebug, Real Intent’s new state-of-the-art design intent debugger and data manager. It employs a full database that captures all phases of CDC verification for the intelligent scope-based analysis of design intent. In addition, iDebug distinguishes the root cause for issues, and minimizes iterations and debug time through an easy-to-use programmable graphical interface. With its powerful command-line interface, iDebug supports a fully customizable sign-off methodology that can be tailored for any design flow.

Real Intent will give presentations on Meridian Physical CDC in Booth #1422 during the Design Automation Conference in San Francisco, June 8 to 10. Appointment times can be arranged here.
