Re: Reference Designator vs ${REFERENCE}
To add to what John says, if you investigate the attributes of each one, one will be on the silk screen layer, and the other will be on the assembly layer. You should be able to turn the appropriate

Re: Reference Designator vs ${REFERENCE}
One, including the value, is to co-relate to the schematic, and might not obviously or unambiguously relate to the location. The other, the plain 'R14' located within the outline, is to show for

Reference Designator vs ${REFERENCE}
Hi, I'm somewhat new to Kicad and PCB design for that matter.? When placing footprints on the PCB it seems that the Footprint Properties by default have both a "Reference Designator" and an unamed

Re: Checking the schematic by SPICE simulation
For opamps and similar, I always draw alternate (de Morgan) symbols, for the different input pin configurations. Then you don't have to tolerate power pins being upside-down, if you flip the symbol.
By Tony Casey · #24072 ·
Re: Checking the schematic by SPICE simulation
Just had a thought, If you normally hide the power pins and have them auto connected, then you can mirror the symbol which will flip the + and - locations. If you have the power pins visible then

Re: Checking the schematic by SPICE simulation
I expect you are right, and I'm into learning still, but it takes time to grasp the nettle.

Re: Checking the schematic by SPICE simulation
Creating libs etc is very easy and moving things from one lib to another is also easy. It's a task worth getting to know. The EDR is not there to tell you that your design won't work, its to ensure

Re: Fixing holes
Thanks; that's how I like help to be presented. I just have to find the Mounting hole library.

Re: Fixing holes
Same here- in Layout, I hit A to add and type MountingHole- grab one and modify it to what I need/want and save it in my own library of ‘1-Mechanical Footprints’ (I add the 1- to make sure it with

Re: Fixing holes
As others have probably said, it is easy (in the PCB editor) to add predefined mounting holes to the board as follows: * Select 'Add Footprint' from the menu on the right-hand side * Scroll to the

Re: Checking the schematic by SPICE simulation
I can accept all you say, but for my limited work I think that creating new libraries is not justified. The point about the opamp is that the EDR won't tell you that you have provided strong positive
By John Woodgate · #24065 ·
Re: Checking the schematic by SPICE simulation
Yes the pin positions are more common with -ive uppermost, but not always. The EDR cannot detect this because it in NOT an error it's just how the symbol was drawn. It's down to the designer to

Re: Fixing holes
When I add Test Points I add a part number for the type I want and I use GRN for Ground, BLK for Digital Ground, RED for Voltages, YEL, and BLU for various other signals... When I add 2-Pin Jumbers I

Re: Fixing holes
Perhaps worth noting that there is also MountingHole footprint library. You'll find a number of standard metric hole sizes already in there.. Regards, Jon
