If youy have LVS clean, you maybe able to ignore ERC error. But if you have soft-connect flag, you need to fix it..
ERC PATHCHK ! POWER && ! GROUND NOFLOAT---- a transistor did not connect to power, nor ground. It is OK if schematic has that.
Soft-connect, two different signals connect to same signal. you either have short, or miss labeled.
In my experience, soft-connect is more serious than ERC. We follow schematc to do layout, if LVS clean, we do not question ERC (you need to let designer know). But soft-error is your responsibility to fix (Layout). |
