Hello all!
I've tried to search the forum and everything for an answer, but that hasn't yielded a proper answer. I'm building a bigger project with many TTL IC's, like the 74LS04, which are using subparts internally. For schematic reasons it's working properly, however some of the IC's set the VCC pin to 5V netflag, while some of them to VCC netflag. How could I tell JLCPCB, that they're effectively the same, so they could be connected together on the PCB? If I create a 5V and a VCC netflag and connect them together, it does work, however it issues a warning when checking for netflags. Ignoring the check could rise some problems elsewhere.
Thank you!
Brand new interactions and interfaces. 
Easy to use and quick to get started. 
"however some of the IC's set the VCC pin to 5V netflag, while some of them to VCC netflag."
I do not understand this.
In simulation until recently, EasyEDA tried to automatically assign VCC and 5V voltage sources but this was almost impossible to get right so, AFAIK, since V6.4.19.3, this has been replaced by warnings to add supply voltage sources.
However this only affected simulation schematics and the placement and naming of netflags to invoke these automatically added voltage sources was under user control.
If you are creating non-simulation schematics then it is up to the user to place and name all nets, netlabels and netflags. EasyEDA does not automatically add or assign them.
Can you make a public copy of a project that illustrates this problem and post the url to it here?
