Description
Extraction
x
Number of sequential cells in the considered LR
Provided by the synthesis reports
x
Number of estimated isolation cells in the design
Obtained by counting the number of wires that connect the different LR among each other in the dataflow model
x
Activation time
Found by means of a high-level (directly on the dataflow) profiling of the targeted scenario
x
Off time
x
Number of retention cells in the design
Strictly related to the LR functionality and is chosen by the designer
x
Power estimation of retention and isolation cells
Determined by the selected synthesis process and can be obtained without any implementation run
x
x
x
Power estimation of PG and CG controller when the LR is on or off
It requires being characterized, according to the target technology, with dedicated synthesis trials

x
Power consumed by combinatorial and sequential cells within the considered LR
Gathered by the reports of the baseline CGR system netlist
