Power Aware simulations play an important role in the System resources block verification. However parametric UPF brings about its own challenges with respect to simulating it in a regression environment. So there is a need to load a dynamically generated UPF based on varying parameter sets. Questa Power Aware helps simplify this effort with loading the UPF in the .tcl format. The parameters like number of watchdogs are set in a configuration file which is used to generate a dynamic test tree which contains a tcl file that loads the UPF. This tcl file is then passed into the optimization stage of the Questa Power Aware tool to load the UPF. UVM tests can now be run with these dynamic test trees to get power aware simulations to cover the wide parameter space.
