System and method for hierarchical power verification
InactiveUS20170011138A1Reduce runtimeReduce memory requirementsComputer aided designSpecial data processing applicationsVerification systemPower management
A hierarchical power verification system and method creates abstract models of power behavior of modules that it successfully verifies. The abstract models simplify the module definition by omitting internal module details but provide sufficient information for power verification of higher level modules that incorporate this abstracted module. Design blocks are replaced with these abstract power models, resulting in reduced run-time and memory requirements. The power models can include power switches inside the block, related supplies of logic ports, supply power states, system power states, power management devices such as isolation logic and level shifters, feed-through and floating ports. The power model may be expressed either in UPF or as a combination of liberty model and UPF. After replacing modules with abstracted models the HPVS can quickly verify an entire SoC with a small memory footprint. When a user modifies a module, the HPVS need only verify the changed module and related modules at higher levels of module hierarchy.

For a circuit path to be represented in a timing model, a set of propagating waveforms substantially converges through waveform stabilization to a uniform waveform at a waveform invariant node and all pins following. The circuit path is decomposed at the waveform invariant node into first and second portions, which are characterized as first and second timing arcs. In computing output slew and delay values, the first timing arc generation factors only a single output load of the waveform invariant node, and the second timing arc generation factors only the uniform waveform. Similarly, a setup arc employs the uniform waveform rather than multiple clock input waveforms in computing setup / hold values. Simulation of waveform propagation is also simplified by simulating only the uniform waveform for the second portion. Additionally, the first arc may be shared between a plurality of circuit paths which share an input pin and the waveform invariant node.
