Hi. The SVRF manual describes the fillmin and fillmax option. Do you have the SVRF manual? Also, you could try reading "Adding Fill" and "DFM Spec Fill" in the Calibre YieldAnalyzer and YieldEnhancer Reference Manual.
I go through svrf and YieldAnalyzer and YieldEnhancer Reference Manual . Its not clear in documentation .
FILLMIN and FILLMAX only apply to 3D fill, where multiple fill is being output, and multiple optimizers are being used.
FILLMIN stops fill being added when any one of the optimizers meets its target.
With FILLMAX the fill will continue to be added until all of the optimizers meet their targets.
Hi Ashish. Does this answer your question?
