FPGA Power On Reset Circuit Actel AX2000

[rhnrgn]

Hello,

I am designing an FPGA board but could not find the reset pin of AX2000. I dont want to add sequencer that is why i want to do Power On Reset.

Can you help me?

Best Regards

It's an FPGA, pick a pin and use it as the reset. The reset is just another input pin and an internal net. Now how you design your reset scheme is another thread altogether.

i am newbie, only part of my job is hardware not embedded design, and also this is my first FPGA hardware design and i wanted to be sure.

Just pulling an I/O to high or low is enough? This is very interesting for me as a MCU circuit designer hahaha.

Thanks mate.

Depending on the internal function of the reset signal, you'll usually want a reset synchronizer that releases the reset synchronously to the design clock. Otherwise the reset effect may have unpredictable results.

Hi,

Basically in FPGA there wont be any dedicated RESET pin. You can use any pin as reset but make sure at power on you need to give a reset pulse. You can connect this pin to any of your controller , if you have in your board. Better discus with your firmware team, how do they want this reset.
