Thanks, I did it already. From this short film I got to know that such properties have to be set.
And I still don't know what I do wrong.
I suggest you contact your local support organisation to try and resolve this.
I found what the problem is.
In case of 2 components that were created by IO Designer, the ground pins have Pin Type = GROUND.
All other components that were translated from Altium library have ground pins Pin Type = POWER.
So in case of these two components I changed the Pin Type property to POWER and no more errors are generated.
But I'm curious where should I define that GROUND property is also OK. I looked to VerifyDefaults.ini file but it is still not clear to me.
Have you tried removing the power net property? You can't have the power net property on Ground nets. I created an Idea (Create a new property that is equivalent to the property "Power Supply Net", but for ground nets ) for a new property for Ground nets
The Verifydefaults.ini in your local home directory defines the global power and ground nets used by the DRC. Here is how I defined it in mine.
<Option Name="ground_nets" Value="GND *GND +0V*"/>
<Option Name="power_nets" Value="+* -* VCC"/>
Hope this helps.
One other thing I have observed. To learn about a DRC on the Mentor support site it is best to search for the exact DRC number. The collections of DRC support information tend to lead to many incomplete entries and dead ends.
