DRC error on regulator output

ElectroJimmy

DE CIS is giving a DRC error on my 5V regulator output because it is connected to a power NET called VCC_BAR.

"ERROR(ORCAP-1628): Possible pin type conflict U13,OUT  Output Connected to Power"

Obviously the error is caused by the fact that the LM7805 OUT pin is identified as a Output pin, which is a fact, And also because the DRC rules in my schematic are set accordingly. Power to Output =>Error

The question is: How do I handle this in the proper way?

Changing the part pin to passive eliminate the error but it does not represent the reality. Power Regulators are utilized all the time for PC-board power and the output must be connected to a power NET. How is this situation handled with respect of the rules and regulations of the PC-board industry ? Cheers

    Have you tried setting the pin type to "POWER" (and visible)? POWER to POWER is acceptable. Output to POWER should cause a DRC since any general output should not be tied directly to a power rail. You can also silence the OUTPUT error or set the DRC level down to a warning by adjusting the DRC settings.

    Makes sense. Assigning the Output pin to Power make more sense then assigning it to Passive and eliminate the problem. DRC is gone and, I agree, the regulator output pin is a Power pin. One as to be aware that it is an Output Power pin. On an engineer point of view, if you are not aware of that fact you shouldn't bother using DE CIS :)
    Cheers
