Power and Delay calculation in Cadence Schematic Editor

[the moon is back]

Hi everyone,

How to estimate the power consumption and delay of a digital circuit in Cadence Schematic Editor?
Simulator used is Spectre.

Please kindly help me in this.

Thanks

Power consumption: integrate current consumption over some time interval, then divide by this time interval. Multiply with power supply voltage.

Delay: see here: View attachment Cadence_tutorial_parametric_analysis.pdf , p.12 ff.

There is also a pwr output available if you go to ADE → Outputs and save all power computations. Then it is also easier to find out which •t your sub-blocks are consuming most /least power. You may also want to check out specremdl if you are doing more advanced/automated characterization.
