In order to correctly compensate for IR voltage drop across the PCB due to high current loads, proper routing of voltage regulator module (VRM) sense lines is critical for maintaining proper voltage levels at the ACAP die.
Note: Be sure to always follow the sense line recommendations from the VRM vendors because regulator designs, pinouts, and requirements vary.
