can't download cyclone IV PCB symbols and footprint lib.

Hi,

Please be noted that Intel FPGA do not provide support for PCB footprint symbols for FPGA and CPLD device families, similar to configuration devices.

However, we will continue the support by providing the schematic symbol which you can download from the link above. You could have the schematic symbol in .olb format from the link below:

Thank you
