I'm running SPICE simulation on a block(CDL netlist from ASIC flow as input file). Ramp the power and measure total area of current spike. From total area of current spike I can get how much decap I need.
The goal is to measure current spike get total area and decap value. The problem is, I want to remove SPICE simulation from above methodology cause SPICE simulation on very big design takes very long time.
How to get decap value or decap evaluation from ASIC flow ? I need advice on which tool or methodology that I can use to get same result.
p/s : I'm very new to ASIC flow and thanks for the advice.
