Apache Design Solutions of San Jose, Calif., has expanded its business relationship and technical collaboration with STMicroelectronics of Geneva, Switzerland, to address the upcoming power and noise challenges associated with 45/32-nm designs. The companies’ cooperative efforts have resulted in the delivery of power and noise solutions for SoC power signoff, low-power design validation, custom IP analysis and modeling, and early-design power/ground grid prototyping. The collaboration expands the Swiss company’s use of its partner’s RedHawk and Sentinel platforms regarding challenges such as 3D-IC power integrity, DDR jitter detection and prevention, chip-package-system convergence and EMI analysis.
