Is there any cheat sheet someone has made for Allegro, I am struggling a little bit with switching between modes for the Layout. ESC doesnt do anything. switching between F3 (trace) and F9 is very cumbersome, and I dont even know how you delete a trace which is proving to be frustrating (Haven't fully competed the learning course from the academy but need something for my own project).
Any shortcut keys for commands, a cheat sheet of list of commands will be highly appreciated.

Also how the heck do you mirror a footprint, there is a mirror command but I am quite certain it mirrors it to the opposite side of the board in 3 dimensional plane rather than along a 2D axis

this may help you: https://youtu.be/042sS4OEKIM?si=p1M1UFAIce7HjqEQ&t=1144

thank you robert

PMICnewbie , 03-29-2024, 04:27 PM

also @Robert Feranec or @anyone how to mirror a footprint along the 2D axis?

QDrives , 03-29-2024, 05:04 PM

Mirror a footprint in 2D??? You can rotate a footprint (180°) or flip it to the other side, but "mirror"?

PMICnewbie , 03-29-2024, 05:07 PM

As in along the X-Y axis

PMICnewbie , 03-29-2024, 05:08 PM

so you can see how I want the VSP3 signal on the outer edge rather than inwards for this switch:

Or is there no way to go about this?

SirJames , 03-29-2024, 05:36 PM

thats something you have to do in your circuit diagram

PMICnewbie , 03-29-2024, 05:38 PM

Oh as in schematic?

PMICnewbie , 03-29-2024, 05:38 PM

thanks do much

SirJames , 03-29-2024, 05:39 PM

yes

SirJames , 03-29-2024, 05:40 PM

also, you have to use thinner lines for Vcc because now they are causing DRC errors

PMICnewbie , 03-29-2024, 05:41 PM

thanks

PMICnewbie , 03-29-2024, 05:50 PM

well I check my schematic, what do you mean change what:

PMICnewbie , 03-29-2024, 05:50 PM

As in the symbol itself?

PMICnewbie , 03-29-2024, 05:50 PM

or the footprint?

PMICnewbie , 03-29-2024, 05:51 PM

I think I guessed my answer, it should be the footprint not anything in ORCAD capture rather the footprint

PMICnewbie , 03-29-2024, 05:53 PM

But can a vendor footprint be changed I am wrong I guess, it will change the connections pin configuration

SirJames , 03-29-2024, 06:12 PM

oh, I didnt know its mosfet. It looks more like a connector to me

SirJames , 03-29-2024, 06:14 PM

well, you cant change pin configuration of any IC because it won't match reality (as in datasheet of your mosfet)

PMICnewbie , 03-29-2024, 06:18 PM

So whats the solution just jump the signal via via

SirJames , 03-29-2024, 06:23 PM

you can go around or go on opposite layer, right?

PMICnewbie , 03-29-2024, 06:32 PM

Yes

QDrives , 03-30-2024, 09:22 PM

A BGA packaged MOSFET.
Well, @SirJames said most of it already. You cannot "mirror' the way you think/want. It is how it is as that is how the manufacturer of the part assigned them.
Beside using a thinner trace for VCC_ARROW, to prevent short circuit (DRC/production DfM) it is no use making the source wider than the drain as the current is equal through both.

@QDrives thankyou
