Real Intent has upgraded its Meridian CDC clock-domain crossing sign-off and RDC reset-analysis tools
The CDC update includes support for multimode-aware dynamic models for flat and hierarchical designs. Meridian CDC adds analysis enhancements to improve low-noise sign-off, including the handling of handshake and interface issues, glitch detection, and reconvergence. For debug, Meridian CDC uses root-cause groups for faster refinement following initial setup compared with traditional manual methods and applies incremental techniques to cut analysis times. The latest version also offers a 30 percent reduction in memory consumption.
With the RDC tool, engineers can now specify targeted flip flops and reset scenarios for more focused runs that complete significantly faster compared to a full design run. For analysis, all waveforms can be displayed to show potential metastability violations which should ease root-cause tracing. Both tools have been given enhancements in terms of faster loading, schematic coloring, and connectivity and context-specific attribute display.
