FPGA工程中会使用 第三方IP的edf 网表。 综合时,用一个black box module (名字和edf中cell名字一致)来替代。 但综合时会报CRITICAL WARNING: [Project 1-486] Could not resolve non-primitive black box cell 。Command: opt_design时会出现DRC 错误。ERROR: [DRC INBB-3] Black Box Instances: Cell 'u_digital_top/u_afe_ctrl/u_D1_MSPM_DIGITAL_TOP' of type 'D1_MSPM_DIGITAL_TOP' has undefined contents and is considered a black box. The contents of this cell must be defined for opt_design to complete successfully.
请教一下这种情况,该如何处理?
