Abstract
A method and a electronic circuit, the method includes: sending to a switching circuit, to a state retention power gating (SRPG) circuit and to a first power source a control signal indicating that the SRPG circuit should operate in a functional mode; coupling, by the switching circuit, a third power grid to a first power grid; supplying power from the first power source to the SRPG circuit via the first power grid, the switching circuit and the third power grid; supplying power from a second power source to a second circuit via a second power grid; sending to the switching circuit, to the SRPG circuit and to the first power source a control signal indicating that the SRPG circuit should operate in a state retention mode; coupling, by the switching circuit, the third power grid to the second power grid; supplying power from the second power source to the SRPG circuit via the second power grid, the switching circuit and the third power grid; supplying power from the second power source to the second circuit via the second power grid; and storing, by the SRPG state information.
