Altium Designer Common unknownpin errors in PCB Design:
The package was not found, the package name was not filled in the schematic diagram, and the pin number was not filled in, resulting in the network was not imported, the pin number was mismatched, and the pin number was missing
I use the footpin not found here because the imported encapsulation is wrong. Another is that its pin number is reversed.
An error is reported in the schematic diagram of cadence when running DRC, and the error information is as follows.
[cadence-DRC]error: Possible pin type conflict GND/VCC Power Connected to OutputSolution:
Step 1: run DRC to find and analyze the error source
Run DRC. After the above error is output, the green circle is error. Click it to display the error message. We can see the green error reporting circle page. Clicking on the pin attribute is connected to the pin attribute output (the output attribute will generate the VCC on the previous page, resulting in the device sharing a VCC network), but normally, the pin attribute is passive/power. Therefore, we manually change the properties of the device pin to normal.
Step 2: Change [edit part] to power attribute
Select the power component, right-click and select [edit part] to enter pin modification in schematic library mode (it is impossible to change pin attribute in this mode), and change output to power attribute (or passive)
Step 3: run DRC again to solve the problem~
