SPIDER – Power Management IP Platform old

SPIDER - One-stop-shop
Power Management IPs

Enabling the safe and fast design of energy-efficient power networks on SoCs.

A comprehensive set of voltage regulators and monitors empowered through a power network and controller generator.

Energy efficiency has now replaced low power as one of the main challenges that the IC design teams are facing. From the adoption of smarter SoC architectures to the selection of the right process node, designers need to find solutions to integrate more and more functionalities in their end product while ensuring maximum performances with minimum energy consumption. At SoC-level, power management is a critical functionality to embed. It enables to control and sequence the way the energy is distributed to each block in the circuit. With more and more complex SoCs and low-power schemes to manage, the integration of power management requires a wide technical expertise from architecture to design and can drastically slow-down the conventional design cycle and increase the risk of silicon failure.
