															好吧。 WARNING:Xst:2677 - Node <ad_d_4> of sequential type is unconnected in block <DDS>. 连线ad_d_4没有连接到DDS模块 WARNING:Xst:1895 - Due to other FF/Latch trimming, FF/Latch <odata1_2> (without init value) has a constant value of 0 in block <V_measure>. ad_d_4输出被固定在了0,自己检查一下什么原因 WARNING:Xst:2734 - Property "use_dsp48" is not applicable for this technology. 是ISE9.1的BUG,后续版本已经修正 http://www.xilinx.com/support/answers/25090.htm WARNING:Xst:2211 - "D:/example/scan/dds.vhd" line 58: Instantiating black box module <sin>. 这个无所谓,不用管 |
