Supply tracking delay element in multiple power domain designs

A method, comprising:

• generating, by a power source, a voltage level on a first power node;
• in response to determining a disable signal is transitioned from a first state to a second state, coupling, by a first power switch, the first power node to a second power node;
• transitioning, by a voltage-controlled delay circuit, a delayed disable signal from the first state to the second state in response to the transition of the disable signal, wherein an amount of delay time between the transition of the disable signal and the transition of the delayed disable signal is based on a rise time of a voltage level of the second power node;
• and
• in response to determining the delayed disable signal is transitioned to the second state, coupling, by a second power switch, the first power node to a third power node.

A system comprising:

• a first set of logic gates included in a first logic path between a first input node and a first output node, wherein the first set of logic gates is configured to:
• receive power from a first power supply signal;
• and
• delay propagation of a first signal for a first delay time based on a voltage level of the first power supply signal;
• and
• a second set of logic gates included in a second logic path between a second input node and a second output node, wherein the second set of logic gates is configured to:
• receive power from a second power supply signal;
• and
• delay propagation of a second signal for a second delay time based on the voltage level of the first power supply signal;
• and
• wherein a number of logic gates included in the second set corresponds to a number of logic gates in the first set.
