asked Aug 4 in Bug by jk

Hello, I found the following error log when attempting to add a note to an analog signal and binary signal.



binary "Vcore Enable" as EN1

analog "Vcore" as VC


0 is high

5 is low

note bottom of EN1: Vcore enable is active low


0 is 0

5 is 0

6 is 1


Log for issue:

Hello J., and all,

FYI see restriction:

You have a first [on 2017] and incomplete implementation. [...]


Then currently note is only available for `concise` timing diagram.
