I am trying to use a Spartan 3 in my design.
The power requirements and current requirement are going to vary according to applications. According to a TI website for Sparatan 3, the VCCINT (1.5v) has the current range from 300mA to 10A, and for VCCO(3.3V) the current range is from 50mA to 3A. For VCCAUX(2.5V) the current is maxed at 300mA.
Has anyone used such high currents when using a Spartan 3.
I will be implementing soft-cores and will be utilizing most of the core. So I am expecting a heavy load on the FPGA. I just wanted to be able to estimate the current that would be required, so I can choose the correct Voltage Regulators. Many of the voltage regulator specify the current limits as 1-2.5A, which may not meet the requirement for upper limit of the current requirement for Spartan -3.
I did post a previous topic regarding chossing a voltage regulator,but I wanted to be more specific on the issue at large.
Thanks for your help.
