错误：小数分频PLL参数’pll_cp_current’设置为非法值

要解决此问题，请找到PLL Quartus II IP文件（ .qip ）文件并完全展开PLL实例名称。

例如：

更改.qip中的以下语句：

set_instance_assignment -name PLL_COMPENSATION_MODE NORMAL -to“* cpui_serial_pll_0002 * | altera_pll：altera_pll_i * | *”

set_instance_assignment -name PLL_AUTO_RESET OFF -to“* cpui_serial_pll_0002 * | altera_pll：altera_pll_i * | *”

set_instance_assignment -name PLL_BANDWIDTH_PRESET HIGH -to“* cpui_serial_pll_0002 * | altera_pll：altera_pll_i * | *”

至：

set_instance_assignment -name PLL_COMPENSATION_MODE NORMAL -to“cpui_top：cpui_top | cpui_serial：sbus | cpui_serial_pll：rx_pll | cpui_serial_pll_0002：cpui_serial_pll_inst | altera_pll：altera_pll_i”

set_instance_assignment -name PLL_AUTO_RESET OFF -to“cpui_top：cpui_top | cpui_serial：sbus | cpui_serial_pll：rx_pll | cpui_serial_pll_0002：cpui_serial_pll_inst | altera_pll：altera_pll_i”

set_instance_assignment -name PLL_BANDWIDTH_PRESET HIGH -to“cpui_top：cpui_top | cpui_serial：sbus | cpui_serial_pll：rx_pll | cpui_serial_pll_0002：cpui_serial_pll_inst | altera_pll：altera_pll_i”

从Quartus II软件版本13.1开始修复此问题。
