HPS power consumption for Arria V SOC using PowerPlay Tool

Hello,

I am new to SOC design. We are using an Arria V SOC chip. I used the Quartus PowerPlay tool to estimate the various

supply currents required. I turned the USE HPS option on in the HPS calculator screen and set the CPU freq to 800MHz.

After running PowerPlay I see a VCC_HPS (1.1V core) current of only 30mA. This seems extremely low to me. I was expecting to see something > 1A at least.

Am I doing something wrong or making some bad assumption?

Thanks,

- Matt Knapp

    I have to assume that you're missing some peripherals as being on, or core usage. I haven't looked at the Arria V setup, but I know the Cyclone V was like that.
