About
Designers increasingly use complex reset signaling architectures to meet high-performance, low-latency, and low-power requirements. Specifically, independent reset domains are created by complex reset sequences, reset circuitry, and the intermixing of IPs with different reset schemas, power-management domains,… Read More

Abstract:
As complexity and the number of clock domains increase in today’s ASIC designs, we are moving towards a hierarchical verification approach. This tutorial covers the proven clock domain crossings (CDC) and Reset Domain Crossing (RDC) schemes, the verification challenges, and the potential… Read More
As designs get increasingly complex, design teams are looking to find bugs earlier, to reduce rework and shorten time-to-market. The ultimate “shift left” is to put easy-to-use static verification in the hands of RTL designers to eliminate bugs at their source.
This webinar covers comprehensive static verification capabilities… Read More

Today’s million gates integrated circuits (ICs) involve various intellectual properties (IPs) interfacing with each other through multiple asynchronous clock and reset domains. Ensuring all clocks propagate concurrently across each clock tree

Manish Pandey, VP R&D and Fellow at Synopsys, gave the keynote this year. His thesis is that given the relentless growth of system complexity, now amplified by multi-chiplet systems, we must move the verification efficiency needle significantly. In this world we need more than incremental advances in performance. We need… Read More
When the number of clock domain crossings (CDCs) in SoCs proliferated it readily became apparent that traditional verification methods were not well suited to ensuring that they were properly handled in the design. This led to the creation of new methods and tools to check for correct interfaces between domains. Now, in automotive… Read More
Talking not so long ago to a friend from my Atrenta days, I learned that the great majority of design teams still run purely structural CDC analysis. You should sure asynchronous clock domains are suitably represented in the SDC, find all places where data crosses between those domains that require a synchronizer, gray-coded FIFO… Read More
Bugs are an inescapable reality in any but the most trivial designs and usually trace back to very deterministic causes – a misunderstanding of the intended spec or an incompletely thought-through implementation of some feature, either way leading to reliably reproducible failure under the right circumstances. You run diagnostics,… Read More
RDC – A Cousin To CDCby Alex Tan on 04-18-2018 at 12:00 pmCategories: Aldec, EDA, FPGA
In a post-silicon bringup, it is customary to bring the design into a known state prior to applying further testing sequences. This is achieved through a Power-on-Reset (POR) or similar reset strategy which translates to initializing all the storage elements to a known state.
During design implementation, varying degrees of… Read More
Because you can never have too much to worry about in verification, reset domain crossings (RDCs) are another hazard lying in wait to derail your design. Which hardly seems fair. We like to think of resets as dependable anchors to get us back on track when all else fails, but it seems their dependability is not absolute, especially… Read More
