Error (10228): Verilog HDL error at try_intel_generic_serial_flash_interface_top_1_qspi_inf_inst.sv(879): module "adapter_8_1" cannot be declared more than once. - Error (10228): Verilog HDL error at try_intel_generic_serial_flash_interface_top_1_qspi_inf_inst.sv(879): module "adapter_8_1" cannot be declared more than once. Description Due to a problem in Intel® Quartus® Prime Pro Edition version 20.2 and earlier & Intel® Quartus® Prime Standard Edition version 20.1 and earlier, you may see the following synthesis error if there are 2 instances of Generic Serial Flash Interface Intel® FPGA IP. Error (10228): Verilog HDL error at try_intel_generic_serial_flash_interface_top_1_qspi_inf_inst.sv(879): module "adapter_8_1" cannot be declared more than once. Resolution To work around this problem, create a custom component in platform designer based on the HDL files generated by the IP. Modify names of modules that have naming conflicts, such as module "adapter_8_1". This problem is fixed starting with the Intel® Quartus® Prime Pro Edition software version 20.3 and Intel® Quartus® Prime Standard Edition software version 21.1.
