Design XC3S200A board

Hello everyone, I am designing FPGA board using XC3S200A, but the pins of Bank 2, the output voltage measured is very low. Is there any solution to fix it?. Does Bank 2 need a pull-up resistor?

Hi @vanthe771996 

There is no need of pull-up resistor on FPGA IO Bank.

How many boards you are observing this issue? How many in total?

Create simple design which can drive Logic HIGH on FPGA pins and check.

Bhushan

thank you, I am a bit confused, the VCCO should be 3.3V, I left it to be 2.5V. Thanks for your advice
