Over-Design, Under-Design Impacts Verification

Designing a complex chip today and getting it out the door on schedule and within budget — while including all of the necessary and anticipated features and standards — is forcing engineering teams to make more tradeoffs than in the past, and those tradeoffs now are occurring throughout the flow. In an ideal system design flow, design teams will have done early, pre-design analysis to se... » read more

Setting Up RISC-V Implementation Verification

This blog provides an overview of STING’s release mode of operation. STING design verification tool is released to the end user in the form of a self extracting script. The script can be used to install the release package in user’s environment. Once the package is installed, the user needs to set few environment variables before the STING executable can be built. The release package ... » read more

Week In Review: Design, Low Power

RISC-V Western Digital announced big plans for RISC-V with a new open source RISC-V core, an open standard initiative for cache coherent memory over a network, and an open source RISC-V instruction set simulator. The SweRV Core features a 2-way superscalar design with a 32-bit, 9 stage pipeline core. It has clock speeds of up to 1.8Ghz on a 28mm CMOS process technology and will be used in vari... » read more

Valtrix Pushes For Horizontal Verification Reuse

Some of the most significant advances are not the result of a single person or a single idea. They often don’t happen overnight, and are suggested by a change that slowly becomes pervasive enough to become a generalized solution. That is exactly what is happening right now in the area of functional verification. The tools and methodologies in place at the moment assumed designs typical of the... » read more
