The CV32E40P core, is the first open-source core for high-volume chips verified with the state-of-the-art process required for high-integrity, commercial SoCs. OneSpin is a key contributor. The OneSpin RISC-V integrity formal verification solution has systematically detected corner-case bugs in the exception logic and pipeline. These issues would only be triggered under rare conditions in the instruction sequence, memory stalls, and Control and Status Register programming. Constrained-random simulation tests to find these issues would require large investments in development and simulation time.
The pinpointing of the issues' root cause was impressive and a massive time-saver in debug time. The solution also showed almost zero noise in detecting real RTL bugs, as opposed to other approaches where the issues reported often lead to fixes in the verification environment.
The complete, formal-based processor verification approach ... uses Operational SVA to formalize the RISC-V ISA and proves that the resulting set of assertions is free from gaps and inconsistencies. This notion of completeness is precise, highly rigorous, and mathematically provable ... Unlike advanced simulation test benches or alternative formal verification approaches, the complete set of properties detects many types of RTL-based, arbitrarily complex hardware Trojans.
"The Connectivity XL approach has been successfully applied to a multi-billion-gate, 7nm Xilinx SoC, delivering conclusive proofs for over one million complex connections, most of them including thousands of signals in the connectivity path, delays, and multiplexing conditions. The approach has detected multiple bugs that would have been much harder, or even impossible, to detect with other formal or simulation techniques."
"The combined engineering effort to set up the extraction of the decoder subparts using the FCA app, and the fault classification using the FDA app was 3 days. ... The overall runtime for the fault classification task for all scenarios reported is under 1 hour."
"Onespin ... supports shared responsibility between design and verification, efficient apps to perform debug and verification, [and] interoperability with the 3rd party Verification Management tools."
"GapFree ensures highest verification quality ... very good improvement in verification productivity"
"Easy and straightforward setup [of EC-FPGA] based on simple template script provided by OneSpin support ... Designs [were] proven to be equivalent after total run time of less than one hour."
“We’re delighted to be working with OneSpin, the leader and innovator in formal verification. OneSpin’s LaunchPad offering has the potential to open new markets to formal verification.”
“The Herkules consortium focused on the verification challenge with the highest return for SoC design projects: getting individual functional blocks and IP right, first time. … The consortium partner, OneSpin Solutions, has implemented these techniques in its formal verification tool, 360 MV. This new verification approach achieves the heretofore unachievable goal of 100 percent verification by a combination of formal property checking and the automatic detection of verification holes. These are the holes that are all too often not found by other formal verification technologies or by using simulation based upon anticipation.”
“Computing hardware fault metrics and achieving targets set by ISO 26262 is challenging, but crucial to enable the application of our massively parallel many-core technology in autonomous vehicles. OneSpin is a trusted provider of apps, methodology and expertise to automate many steps of this process. Working cooperatively with its engineers smoothed our path to ISO 26262, savings months of project time.”
“We achieved IEC 61508 SIL 4 for the fault avoidance measures during development of the functional safety controller vCOSS S-zero®, a challenging endeavor for this type of equipment. We used a number of technologies to meet SIL 4 requirements, but equivalence verification using OneSpin’s EC-FPGA and EC-RTL was indispensable.”
“You can optionally use the third-party OneSpin 360 EC-FPGA* sequential equivalence checking tool to verify the logic equivalence between specific netlists following compilation. The 360 EC-FPGA software can help you to confirm that aggressive Compiler optimizations do not introduce unexpected results.”
“OneSpin Solutions has created innovative formal-based design verification and equivalence checking solutions that are being used to fully vet some of the most safety critical designs in production today. We believe that by including equivalence checking as part of the design flow, we will better meet our customers’ stringent requirements for high-reliability designs.”
“Results of the application of the FP ABIP as part of the OneSpin FPU App in industrial applications show that corner-case bugs can be unveiled within seconds, and unbounded proof achieved within minutes, even for the multiplication operation. These results were obtained without the use of abstractions or assume-guarantee partitioning.”
“The MicroSemi ProASIC3 FPGA is a core component of the Advanced Logic System (ALS), and use of the OneSpin 360 Equivalence Checker is an integral part of our FPGA development process for nuclear safety systems.”
“OneSpin 360 DV can identify issues early in the design cycle, when it’s easier and more cost effective to make changes.”
“We were looking for a verification method that significantly increases the performance of our functional verification for the MCU platforms. We selected OneSpin's 360 DV technology because it provides the best solution for our needs for advanced capabilities to enable functional verification during the product deployment phase of platform development in a significantly shorter timeframe than logic simulation. The ease of use of Operational ABV, combined with the capacity and performance of 360 DV, saves significant effort in the Renesas Electronics functional verification flow compared to logic simulation.”
