ello, I'm using current_region to add additional current in a few areas of the circuit. Consider the two following scenarios: Scenario 1: vdd_gnd_worst.iv (with current regions) current_region_10 0.86666 blob U322 0.86669 STD_CELL_1 current_region_13 0.86669 blob current_region_20 0.86671 blob ... vdd_dynpwr.report (with current regions) => peak of dynamic current used = 9.952838e-03 Scenario 2: vdd_gnd_worst.iv (without current regions) U322 0.95677 STD_CELL_1 U1889 0.95685 STD_CELL_2 U1782 0.95688 STD_CELL_3 ... vdd_dynpwr.report (without current regions) => peak of dynamic current used = 6.815154e-03 My questions are: 1) Since we see current_region_10, etc. in .iv files (meaning that there's IR drop in that region), it means that even if we apply current regions in areas where no cells are affects, a "fake" additional power will be added to the dynamic power report? So, should I discount in the total dynamic power, the power induced by current regions that didn't affected any cell of the circuit? Or the power report already discount current regions not affecting any cell? 2) When I create several current regions that by my calculation should add, let's say 20 mA of additional current, in the final dynamic power report I have much less than expected (considering Gnd and Vdd rails). Is this expected? My guess is due to current regions that doesn't affect any cell, which is related to the first question. Thank you, Raphael![]()
