To bug or not to bug - Min. Width for Differential Pair
mulfycrowh , 08-31-2023, 01:36 AM
Hi everyone,
I wanted to make some tests: I set up the Min. Width on bottom layer in Differential Pair Routing rule to a lower value than previous one: 0.09 mm instead 0.23 mm.
Everything fine.
Then I wanted to set it up again to 0.23 mm.
AD tells me there is an error: Some rules have incorrect definitions.
Fixed when set up to 22.9 mm.
Did you already have this issue?

22.9mm? That is even wider than my widest 'trace' of 14mm 
Which version of AD?
The reason for me asking is that a colleague of mine recently updated to the latest 23.8.1 and had problems with sheet entries. Input sheet entries would not draw correctly when modified/added.
Oh, and make sure that the . or , (period and comma) for your language setting are not the problem.

I drink too much and it makes me see the tracks wider than they are...
Hawful...
But seriously speaking I don't understand the issue. I just changed the value from 0.23 mm to 0.09 mm and then back to 0.23 mm.
AD declares an error.
I don't think it is an issue with , or . because I made 2 times: one for DisplayPort, one for HDMI.
And then I set it to 0.229 mm and it is OK.
I also tried 0.2299, AD rounds it to 0.23 and triggers the same error.

Does it give an error in the rules editor or with the DRC?
What happens if you set the rule to 0.25 or 0.3?
