Could not allocate the following pins to any bank: - <number> pins at <voltage> mV in the Intel® FPGA Power and Thermal Calculator (PTC) - Could not allocate the following pins to any bank: - <number> pins at <voltage> mV in the Intel® FPGA Power and Thermal Calculator (PTC) Description Due to a problem with the Intel® FPGA Power and Thermal Calculator (PTC) in the Intel® Quartus® Prime Pro Edition Software version 20.3 and earlier, you may see this error even if there are still available pins when differential input pins are used and the VCCIO voltages of all I/O banks are not 2.5V in Intel® Stratix® 10 devices. Here is an example. Device: 1SG280H Package: F50 Number of user I/O: 672 Number of I/O bank: 14 Number of pin pre I/O bank: 48 User I/O usage: 1.2 V output * 625 pins LVDS input * 1 pair In this case, since 625 pins are used for 1.2 V output, the VCCIO voltages of 14 I/O banks are 1.2 V. LVDS input is powered by VCCPT, not VCCIO. So a pair of LVDS input should be able to be assigned to remaining pins, but the PTC incorrectly displays an error as shown in the following image. Resolution You can safely ignore this error. This problem is fixed starting with the Intel® FPGA Power and Thermal Calculator (PTC) in the Intel® Quartus® Prime Pro Edition Software version 21.3.
