OCV Derating With AOCV

Posted on Edited on In

timing_aocv_derate_mode

timing_aocv_derate_mode{aocv_multiplicative | aocv_additive}

Default: aocv_multiplicative

Controls the AOCV derating mode.

When set to aocv_multiplicative, the derating factor will be calculated as AOCV derating * OCV derating, which is set using the set_timing_derate command.

When set to aocv_additive, the derating factor will be calculated as AOCV derating + OCV derating values.

When you use this global variable, the report_timing command shows the total_derate column in the timing report output, which allows you to view and cross-check the calculated total derate factor.

To set this global variable, use the set_global command.
