Multiple Voltage Design

MODERN TECHNIQUES                                                      Modern IC designs are heavily influenced by the need to minimize power consumption, particularly in the consumer electronics market. The devices' warmth, battery life, and the time it takes to switch on and off the functions of handheld devices are currently being reformed. Therefore, it becomes crucial to implement best practices in chip design to help reduce power consumption in SoCs (System on Chip). The power management of SoCs and RTL designs has a significant impact on the silicon's performance. Power-aware designs are used by industry to achieve power statistics. This blog focuses on multi-voltage design terms that can be used to assess the power performance of silicon in HDL coding. These facilitate the understanding of design parameters while implementing power-consciou...
