New ContributorCyclone V GX C5 CRC_ERROR pin
I have a vendor (Terasic) board and I turned on the CRC_ERROR pin. Quartus Prime complained that Pin V20 is mapped twice. Is there a reference to the what dedicated pin is mapped to CRC_ERROR for the Cyclone V series? I have the handbook, device overview and data sheet. However, I could not locate a reference to tie pad V20 to CRC_ERROR.
Our intent is to transition to a custom design and currently this pin is a 3.3V LTTL input, but I can remap that to another pin. I understand that it should be connected to VCCPGM via a pull-up. I just wanted to be certain to reserve this pin for eventual dedicated use as the CRC_ERROR pin.
Thanks for any references and sorry if I have missed this information somewhere.
Sorry, it is an F27 package. Probably because of the package options, there are a lot of possibilities and maybe a manual has not been published with the dedicated pins for this reason. I was looking for the banks to pad mapping as well, but the pin planning tool seems to provide this. I will take a look at the layout guide again.
Hi,
Thanks for the update. Just to let you know, this case was set to close as we did not received any update from you after my final response.
For pin assignment for CRC_ERROR and V20, you may refer to pinout file and mapped it accordingly. Do not need to assign using pin planner. Please ensure follow the pinout file and guidelines.
