大家好，我是一个新手，在学习数字后端使用Astro的时候遇到一个问题，希望各位前辈能够给予帮助，先感谢大家。问题如下：我在进行PAD的连接时发现我的VDD一直无法连上，观察命令窗口时发现遇到VDD引脚处一直显示warning，也看不出是什么原因引起的。GND也存在warning，不过是由于M1层没有使用而引起的，无关痛痒。
操作方式：PreRoute > Macros/Pads…
Scheme命令：

axgPrerouteInstances
setToggleField "Preroute Instances" "Instance Type(s)" "Cover" 0
setToggleField "Preroute Instances" "Instance Type(s)" "Macro" 0
formOK "Preroute Instances"
Warming内容：

可能是设置的问题吧，或则是fp的问题

Check your PAD FRAM to see location of VDD/GND pin.
There are only PAD(VDDtoCore) and PAD(GNDtoCore) have PINs can connect to CORE. In this case you might not have core ring yet that why no connection can be made.

I follow the report that only uses IO and STD lib,no PAD lib,and the result in the report is correct.I also follow the steps,but I cannot get the same result,so I comfuse whether there are some other reasons that lead to this problems.
