Schematics says DNP. what do I put in ?
In the datasheet of the A/D converter that we are using, the schematics contains a Resistance R26 and says DNP (Do Not Populate) below that. I am trying to replicate that part of the circuit. I dont understand what resistance I need to put in my schematics ?

resistor dnp
«Do Not Populate» means exactly what it says — do not put a resistor there.
It is typical for design work to include extra components that are used only during
development. They are discarded in the final product.

What are the testpoints on an Altium board?
Test to ensure that intentional end-to-end contiguous copper carries a clean signal (under a maximum permissable impedance threshold) without any open-circuits. Test to ensure that nets are not shorted to each other.
How are test points created on a PCB?
These “test points” need to be known and cataloged in the Printed Circuit Board design system for reports to be generated that the manufacturer will use when testing the finished boards. To do this you will create test points on the board by flagging pads or vias as probeable points.
How are testpoints positioned on a circuit board?
Testpoint locations can be required to be positioned according to a minimum clearance with respect to the board edge. The process of contacting the board with a flying probe pair or a bed-of-nails array of probes can be tough on the board itself, and the board may flex to some extent under the strain of automated testing.
When do testpoints not need to be tested?
There are occasions where specific pairs of testpoint locations are not tested in-concert by a flying probe. This is typically the case when there is no danger of a short (or crosstalk) between nets, as the nets are not adjacent to each other (all objects of both nets are mutually separated by their physical proximity).

hey guys welcome back to my basics of all team series uh today will be the last video on schematic layouts before we move on to pcp uh and this video will go over dnp’s erc’s and differential pairing setup so starting off if we want dnp components that is we want components that are not typically populated and we can do this for various reasons um to give a little bit more flexibility to our design or if there’s variations of your board so in one in one design a certain resistor value will modify the output what we can do is if we were to place a new part and say all these over if we want an option where instead of a 22 kilo pull down we want a 110 kilo ohm pull down but we want it known that the default is 22 we don’t want this 110 to normally be populated easiest way to go about it is to place a text go tab just in big bold letter d and p decrease the size a little bit usually change it red make it bold placing it and place it right over the component so now when you come back to your schematic to actually manufacture your board you’ll come through and you’ll see that this let’s quickly annotate that this r4 is not normally meant to be populated so that will allow you to make sure that you don’t accidentally populate this and then you have a problem in your design similarly if you have a pin that’s meant to be floating so if we pretend this p ground was optional what we can do is place directives no brc so it’ll just create a red x on our system this way when we’re going through our schematic we can go and we can see that this pin was intentionally left floating um when we placed this we we know that this was purposefully left blank and not that we accidentally missed anything so when you’re going through on a review or you’re coming back to the project maybe months later you’re trying to debug the system if you come across a floating pin but it has a red x on it then you know this was intentional i didn’t accidentally just mess it up you know you know that’s not going to be the cause of your problem now we have how to do our dnp and how to do our uh generic ercs um and if we want to be extra safe what we can do is place a note and you can come in and say he change it’s or if we wanted to we can say populate part 4 if we want 3.3 volts outputs so this way we can have notes left around our schematic to give meaning to why something was done it’s often good practice to come through and put as many notes as you can so sometimes that’s you’ll put your math to explain why you’re doing a 124 and a 22 as your voltage divider on the feedback you can put in your math to show this means by volts or whatever your you know switching frequencies in your adductor you can put your math to say why you chose a 3.3 it’s generally just good practice to keep as many notes as you can so it’s easier to come back to and debug your system or understand your system if we want to look at differential pair routing um this is typically used for high-speed communications or signal reading when the differential signals are in play in our case we can say we’re doing current sensing off of our 12 volt line so we’re putting a super low one ohm resistor and it’s going to go off sheet to it’s going to go off to one of our other schematic pages so we have our i sense it low now because this is going to be it’s going to go into a different drop amp and it’s such a low resistance it’s going to be a low voltage measurement between these two lines um keeping our routing when we go to the pcb is going to be critical to keep them as equal as possible um so to set that up on the schematic what we can do is place directives differential pair and by placing one on each and then changing the net names to be five cents p extents n we have now set up these two lines to be uh as differential pairs uh there’s there’s two steps to actually making it work is first off you have to place the differential pair um symbol on both lines and then the naming convention when you’re placing your nets is to give it whatever its name underscore p and then the same name underscore n so now all team automatically knows these two wires are meant to be paired up together so when we go into our pcb we can do differential pair routing and it’ll automatically pull these two wires together so that they’re always at a constant distance the final schematic cleanup item that we may want to do before we conclude is sectioning off doing some drawings so if we go place drawing tool line create a bigger line this is just sectioning off your schematic making it easy to read um if we break this off and we go place text again call that buck converter and call this one connectors and then current sense um this is one way to make our schematics more broken up and readable when we’re putting multiple smaller systems on a single schematic instead of just putting everything on independent pages we can draw lines and put net and put names to break up our schematic with that that’s the basics of everything schematic related so in the next section we’ll be going over more of the pcb design
Thanks for your comment Sunny Potaczala, have a nice day.

hey welcome back in this video i want to talk about variance if you haven’t made the variant already and you might have i think i might have done the variant already then that’s fine we will discuss variants in the schematic the schematic isn’t completely finished it’s not done i hope you finished your schematic up to this point already if you haven’t you can see the reference design and finish the schematic or you can just look at this you can pause this and finish your schematic this way from the parts that are in your library that you either fixed up yourself or that you got from the download link in the description from the previous videos so now once we have our parts placed we need to set this led as a do not place so let’s go ahead save our project under here we want to right click and choose variance now we don’t have any variance here so we’ll create one choose add variant i’ll call it v01 okay you can allow fab variation of fabrication outputs i won’t do that now i just click add excuse me hit cancel click ok now this adds a column to your list now sometimes you may not see this you may have something go like this where you barely notice that and you only see this thing and then it shows you the details for each part as you select it bring this down if that happens great this part here this led one i want it to be as a do not place component so you can click on here and click on the ellipses and choose not fitted or alternate part you know so click ok you can choose the drawing style to indicate not fitted parts so we have use graphics you can use the red cross you can use the gray box with dmp i like to use the red cross with dmp just a default and then you can hide not fitted components you can display not infinite components and draft it’s up to you click go with the defaults now um that’s that’s contradictory right it’s up to you but go with the defaults all right so now you can click ok you can also add additional variants as many columns as you want really and then choose what fit what is fitted what’s not fitted click ok now why does it look the same way that’s because we’re editing the schematic we can view we can take a look at what the schematic looks like when we view it but see there’s no cross here ah okay that’s because we’re in the no variance option if we if we want to see the other one we can right click and set this as the current version of the schematic we’re looking at and we have our editor but when we go to live battery and with how it’s viewed on printing this is how it looks now here’s another way you can do variants you can toggle if a part is not fitted or fitted by clicking on this icon here and then say you know you don’t want for whatever strange reason you don’t want this diode here you can do that and it’ll show up as do not place i’m going to click that to toggle it and then right click to get out of that mode now let’s go back to the editor we’re going to continue working in this version one variant for now why are we using this variant it’s because uh if you have fitted or non-fitted components this also affects the billing materials in the next video i will discuss more about how you can use the variant in the bill of materials and to generate a bill of materials
Thanks Juan your participation is very much appreciated
