在进行connectivity检查时，有错误，可能是哪几个方面的原因？

就是没有完全走通.

没有啊，鼠线都走完了，出错的地方都是在已经步线的地方，而经检查，连接没有错误呀，都是按照鼠线连接的呀，如有的在接地的热焊盘上打了一个connectivity错误的标志，可这个管脚就应该接地的呀；还有的在某条线上打了个错误的标志，可这条线的连接也没有错误啊。请各位帮帮忙，本人很着急，百思不得其结，请各位指点迷津，谢谢！

再顶下，请各位指点呀

请各位帮忙呀

肯定是有问题，你把你所画的线关闭，在看有无鼠线就可以了，就知道有无连完没有了

检查了，的确没有鼠线，都布完了。下面的是出错信息，麻烦各位帮我看一下，谢谢。Isolated subnets for: MD6*** subnet # 1 U11.11 U29.11 U8.9 VIA(-4030,1030 L1) U10.11 VIA(-5055,1025 L1)*** subnet # 2 HATCH OUTLINE(-4338.93,1005.57 L1)Isolated subnets for: GND*** subnet # 1 HATCH OUTLINE(-6479,3510.26 L4)*** subnet # 2 HATCH OUTLINE(-2824,1897.94 L4)*** subnet # 3 HATCH OUTLINE(-3379.43,2409.36 L2)*** subnet # 4 C92.2 VIA(-3240,3260 L1)*** subnet # 5 VIA(-8160,3720 L1) R189.1*** subnet # 6 HATCH OUTLINE(-6584,780 L1)*** subnet # 7 HATCH OUTLINE(-6782.9,820.08 L1)*** subnet # 8 HATCH OUTLINE(-8128.73,3621.09 L1)*** subnet # 9 HATCH OUTLINE(-5942.53,3698.25 L1)*** subnet # 10 HATCH OUTLINE(-5822.53,3698.25 L1)*** subnet # 11 HATCH OUTLINE(-4792,2002 L1)*** subnet # 12 HATCH OUTLINE(-5784,2139.94 L1)*** subnet # 13 HATCH OUTLINE(-2465.41,4186.46 L1)*** subnet # 14 HATCH OUTLINE(-3706.87,2444.2 L1)*** subnet # 15 HATCH OUTLINE(-3634.2,2391.43 L1)*** subnet # 16 HATCH OUTLINE(-4128.72,3148.13 L1)*** subnet # 17 HATCH OUTLINE(-5048.71,1133.96 L1)*** subnet # 18 HATCH OUTLINE(-2213.28,35 L1) HATCH OUTLINE(-1975,896 L1) HATCH OUTLINE(-1174,717.71 L1) HATCH OUTLINE(-1174.12,428.58 L1) HATCH OUTLINE(-1670,230 L1) HATCH OUTLINE(-3564.01,1913.28 L1) HATCH OUTLINE(-3409,4111.98 L1) HATCH OUTLINE(-3360.9,4108.07 L1) HATCH OUTLINE(-3360.62,3828.06 L1) HATCH OUTLINE(-3795.53,2146.12 L1) HATCH OUTLINE(-3510.45,2285.71 L1) HATCH OUTLINE(-3378.98,2232.02 L1) HATCH OUTLINE(-3403.22,5159.06 L1) HATCH OUTLINE(-3563,4364 L1) HATCH OUTLINE(-3890,3499.37 L1) HATCH OUTLINE(-4009.99,3444.51 L1) HATCH OUTLINE(-3794,3419.08 L1) HATCH OUTLINE(-4046.15,2190.04 L1) HATCH OUTLINE(-3597,3417 L1) HATCH OUTLINE(-3595.39,3296.48 L1) HATCH OUTLINE(-3736.48,5159.7 L1) HATCH OUTLINE(-3716.28,5149.5 L1) HATCH OUTLINE(-3709.37,4230 L1) HATCH OUTLINE(-4056.41,1602.69 L1) HATCH OUTLINE(-4002,1542 L1) HATCH OUTLINE(-3996.29,1251.68 L1) HATCH OUTLINE(-3887,1542 L1) HATCH OUTLINE(-3871.56,1458.25 L1) HATCH OUTLINE(-3728.59,1113.28 L1) HATCH OUTLINE(-3819.26,4396.4 L1) HATCH OUTLINE(-3725.16,4300 L1)Isolated subnets for: +3.3VD*** subnet # 1 HATCH OUTLINE(-5168.43,3149 L4)*** subnet # 2 C50.1 VIA(-3950,3220 L1) U8.101*** subnet # 3 HATCH OUTLINE(-5006.48,1119.1 L1)*** subnet # 4 HATCH OUTLINE(-4619.64,2233.5 L1)*** subnet # 5 HATCH OUTLINE(-5152.88,2215.37 L1) HATCH OUTLINE(-3395,3103.28 L3) R25.2 R27.2 R24.2 FB8.2 EC20.1 R23.1 VIA(-3955,3005 L1) U8.58 C45.1 VIA(-4770,2080 L1) C44.1 U8.2 VIA(-5155,2235 L1) U8.191 U8.157 C42.1 VIA(-5565,3205 L1) R176.1 VIA(-4710,3465 L1) U8.133 R20.2 VIA(-5520,2855 L1) VIA(-3910,2285 L1) FB14.1 C49.1 VIA(-5325,2585 L1) C43.1 U8.34 VIA(-4470,2035 L1) C46.1 C51.1 R26.2 U8.50 C48.1 VIA(-4155,2060 L1) VIA(-3860,2040 L1) C47.1 VIA(-4195,2240 L1) U8.20 R191.1 VIA(-3435,2940 L1) R190.1 VIA(-5600,2975 L1) VIA(-4940,3770 L1) U8.91 VIA(-5050,3765 L1) VIA(-5025,3625 L1) VIA(-5130,3630 L1)Isolated subnets for: +1.8VD*** subnet # 1 HATCH OUTLINE(-4389,2621.25 L4)*** subnet # 2 HATCH OUTLINE(-3755,2735 L3) FB7.2 U8.63 VIA(-3940,2460 L1) C38.1 VIA(-4905,2075 L1) C36.1 EC19.1 U8.124 VIA(-4500,3460 L1) C40.1 U8.189 VIA(-5335,2645 L1) U8.12 U8.37 C37.1 VIA(-4390,2030 L1) C39.1 U8.81 C34.1 C35.1 VIA(-4420,2255 L1) VIA(-4110,2820 L1) U8.170 VIA(-5405,2975 L1) U8.159 VIA(-5140,2945 L1) VIA(-5345,3225 L1) C33.1Isolated subnets for: +3.3V*** subnet # 1 HATCH OUTLINE(-2775,2638.28 L3) C178.2 U21.4 U21.2 R148.1 VIA(-8005,3720 L1) EC79.1 U22.3 EC83.1 VIA(-6580,4360 L1) C175.2 C173.1 R150.1 C172.2 EC82.1 FB8.1 FB9.1 R31.1 R143.2 VIA(-5670,3685 L1) FB12.2 U9.13 U9.37 VIA(-5675,4515 L1) C58.1 VIA(-6010,3470 L1) VIA(-6000,2575 L1) VIA(-3705,3615 L1) FB10.1 VIA(-5740,1920 L1) C176.1 VIA(-5905,2125 L1) R169.1 VIA(-2855,3905 L1) R53.1 VIA(-6510,1715 L1) R52.1 VIA(-6425,3430 L1) VIA(-5970,2230 L1) VIA(-6425,3235 L1) VIA(-3170,2385 L1) LED2.1 VIA(-6575,3920 L1) VIA(-6555,4475 L1) VIA(-6580,4210 L1) VIA(-6530,4360 L1) VIA(-6485,4270 L1) C57.1 U23.8 U9.14 R51.1 R156.2*** subnet # 2 HATCH OUTLINE(-3606,2289.94 L1)*** subnet # 3 HATCH OUTLINE(-3846.95,2395.62 L1)

明白了，是因为我没有FLOOD/HATCH就进行检查了，使某些VCC/GND没有被连通。
