Why does the FPGA Power and Thermal Calculator (PTC) and Quartus® Power Analyzer (QPA) underestimates/overestimates the static power consumption of the HBM resources?

Description

Due to a problem in FPGA Power and Thermal Calculator and Quartus® Power Analyzer (QPA) version 23.4 and prior in the below use cases, the static power estimation for HBM resources might not be accurate. Power Supplies affected by these issues are VCCIO_UIB* and VCCM_PUMP_HBM_*

If the type of HBM used is 16GB

Number Of Used HBMs	Inaccuracy
0	PTC Underestimates By ~ 0.5 W
1	PTC Underestimates By ~ 0.5 W
2	PTC Overestimates By ~ 0.5 W

If the type of HBM used is 32GB

Number Of Used HBMs	Inaccuracy
0	PTC Underestimates By ~ 1.05 W \| QPA underestimates by ~0.5
1	PTC Underestimates By ~ 1.05 W \| QPA underestimates by ~0.3
2	0

Resolution

This is scheduled to be fixed in the future release of the FPGA Power and Thermal Calculator (PTC).
