altfp_mult 的输入应该是浮点表示方式。也就是说，你要仿真3.3*1.1的时候，输入端要是3.3和1.1对应的浮点表示方式。可以用matlab先事先转换好数值。需要说明的这个IP的输出相对输入有好几个周期的延时，6个还是12个，忘了。软件里应该可以看到 你看下这个文件的技术资料啊

I've found I cannot even open the MegaWizard for the IP that won't upgrade (ALTFP_MULT and ALTFP_CONVERT) that bails out without notice only leaving an "iplauncher_debug.log" file with the line "Fatal Error: The file altfp_mult_info.xml does not exist or can...

加法器IP核是Arithmetic下的ALTFP_ADD_SUB,设置是double precision,output latency是8。 仿真时输出一直是0,偶尔给特别大的输入时,输出也会为一个特别大的数。 请教各位怎么解决这个问题??谢谢各位:) 0 2015-6-25 16:05:50 评论 淘帖 邀请回答 lken1992 相关推荐 • 一个关于QUARTUS自带乘法核的问题...
