How to Set Different Net Clearances

You need to use the Net CLASS-CLASS rules. Go to YouTube and search for the parsyseda channel then look for Spacing Constraints and watch the video which covers this. 

Thanks for your answer, I've had a look at your video and I'm not sure if this works the way my Constraints are set up.

I have all my nets with a standard CSET of Default, I then have specific nets in a Class HV which I've set to CSET COATED_400V.

What I require is the nets in Class HV to have a Default Clearance; however to all other nets they should have a clearance of COATED_400V

I've not quite set things up correctly, can you advise how to  best set this up, when I select Class to Class the Default does not appear

Thanks

So you need to put all the nets in Netclasses, this can be individual (like Power, High Speed, etc) or just put all the remaining nets into one class called Default or Remainder. You can then create CLASS-CLASS rules for each. Default to HV would use the Coated Cset but Default to Default would just use your Default CSet.

All Sorted Thanks
