There's a bummer. :scared: Perhaps you'll be lucky and there'll be a .bak file intact. |

I just finished redrawing the entire schematic. But this time I felt a little more comfortable and fast. Thanks a lot for your help. I followed your suggestions and now have only 2 warnings on the DRC. The errors are being inconsistent. --- Code: ---***** Sheet / ErrType(3): Pin connected to other pins, but not driven by any pin @(62.23 mm, 161.29 mm): Pin 2 (Power input) of component U1 is not driven (Net 16). ErrType(3): Pin connected to other pins, but not driven by any pin @(275.59 mm, 148.59 mm): Pin B12 (Power input) of component J3 is not driven (Net 18). ** ERC messages: 2 Errors 0 Warnings 2 --- End code --- The error on Net 16 won't go whatever I do. But, the error on Net 18 is fixed if I delete the wire connecting the B12 pin and redraw it. But a same error on occurs on the any of the capacitor in VOUT and SW network connecting to the ground. Again if I fix that the same errors is now shown on pin B1. I'm attaching the schematic as PDF below. Happy Thanksgiving. |

U1 is not driven: ERC isn't that smart. I wouldn't expect it to consider it driven through a resistor. By default, ERC requires that there is a power output (which may be a flag) on every net that connects to a power input. (But you can adjust the ERC rules in the Options tab of the ERC window.) I suspect you might have another multi-named net on the ground net somewhere but I can't tell for sure as you missed the attachment again... Thanks, and same to you. It's Black Friday, stay safe out there. :) |

Don't sweat it. Anyway, for consistency, since you're using ERC, may as well add the power flag to that net near the bottom of R1. Speaking of consistency, I see that you're using a GND sheet label instead of a ground power symbol to connect pins A/B-1/12 of J3. ERC might not appreciate that, especially without any PWR_FLAG drivers on the GND net (that I can see). Other than that, looks good. Ship it! :) |
