Synchronization failures are a common pitfall in multiple clock domain designs. These bugs are hard to fix, because the failures are often intermittent and hard to catch. Fixing such bugs in FPGA may take weeks of debugging, and they may be impossible to catch in ASIC prior to fabrication.



vSync Circuits Vincent Platform delivers a twofold solution to this problem. The vGenerator tool provides the necessary fool-proof synchronizer customized for each interface and each clock domain crossing. The vChecker tool verifies the complete design statically, hunting for trouble and assessing expected reliability.



Unlike typical clock domain crossing (CDC) verification tools, the vSync Circuits Vincent Platform focuses on providing the correct solutions, rather than merely pointing at the problems. Vincent Platform is compatible with all types of digital design flow, having a fast and easy deployment.



The advanced abilities of vSync Circuits Vincent Platorm provide a complete solution for multiple clock domain ASIC/FPGA integration and CDC verification, covering all the stages of the VLSI design flow: from the RTL design down to GDSII/Bitsream.



…We evaluated a number of leading CDC tools and we chose vSync Circuits Vincent Platform as a main tooling for CDC treatment starting from the design stage, through simulations and down to static verification of the product before starting the lab testing. …Vincent Platform is successfully employed both for legacy and new designs, identifying bugs in the existing systems and improving the design stability for new designs by employing the vGenerator solutions. …vChecker tool is very easy to use, with a convenient bug tracking and cross reference abilities, allowing fast problem understanding and fixing. …The provided support is very responsive, and along with on-site training conducted by vSync Circuits, it enabled a good adoption of the tools inside our group. …To summarize, we are highly satisfied by vSync Circuits tool kit both at the technical level (problems identification, solution generation) and also at the user experience level.
