Siemens' Todd Westerhoff highlights the importance of signal integrity analysis in PCB design, challenges as simulation tools have become more sophisticated and difficult to use, and best practices like starting with a simple analysis problem. Synopsys' Rita Horner, Shekhar Kapoor, and William Ruby note that the power and thermal profiles of multi-die systems for HPC and the data center shou... » read more

Startup Funding: August 2023


August startup funding continued to follow the trends that put AI and autonomous driving at the top of funding. One of August's largest rounds went to a company designing AI processor IP that can scale from the edge to the cloud. Plus, three battery manufacturers brought in one billion dollars or more. This report covers 37 companies that collectively raised $4.2 billion in August 2023. [... » read more
