Hello Ismail,
I have used Spartan IIE FPGA with Texas Instruments
REG1117A LOW DROPOUT POSITIVE REGULATOR.
I have done signal testing on it as well and it works very well on my board.
Make sure to have high & low frequency decoupling for the output.
Regards,
Ruturaj
Hello there!
I want to know if anyone used SPARTAN IIE FPGA in any of their design. It
seems that
the FPGA draws a high current during start up which appers almost like a
short circuit
I am in the process of selecting an appropriate Voltage regulator but not
sure how good
it will be. My worst fear is that once the Voltage regulator senses the high
current draw
it may shutdown. It will be of great help if anyone could provide the part
number/manfacturer
of Voltage regulator used in their earlier (working :) ) design.
Thanks,
Ismail
