Hello, welcome back. And in this video I'm going to show you how to make your first schematic simulation and printed circuit board in the capture cis light and PCB editor software suite. So let's go to the start menu here and choose all programs. Next, I'm going to scroll down to the cadence for the 17.2 folder. I have a lot of software packages installed here under this cadence release 17.2. So just ignore these folders here.

Now what you should have is just the orchid lite product suite. So I'm going to go in orchid light here. And you should have capture cis like so click on that. This is a software tool that's going to help you create your schematic or your drawing for your LED. So go to File, New Project. Then name it led.

Make sure it's a piece of ice analog or mixed ad option for your project here that allows it to be seen simulated. Now, under location, click the Browse button here. I'm just going to put this project in the Documents folder. So click New Folder. I'm going to name it led. Go into the folder here, select it, then click OK.

I'm going to create a blank project. So make sure to create a blank project here and click OK again. And capture cis will load a new schematic page for you to put your circuit onto. Now, there's a lot going on here. But there's a lot of things that you don't really need to know just a few things that you do need to know to get your schematic made. First, it's the part place option.

So go over here to Quick Access toolbar and choose placed part or hit p on your keyboard for short. That will open up the place part window and you want to type in our four resistor. Now that shows up here for me because I already have this library Add it. But in case you don't have that library, if it's your first time using the software, look under libraries here, and then choose the Add library option. R is in the analog folder. And that would be this right here.

This is a library and I'll explain this later on in the course. But these are libraries that has the parts that you need. So choose analog dot o lb. And when you type are in the part search field, it shows up, hit Enter on the keyboard so it gets attached to your cursor. Alright, now I want to rotate this part so right click, choose rotate that rotates it there and just click once to place it onto the schematic. Next, you want to add a VDC it doesn't show up.

And that's because I don't have the library selected that would house the VDC. In case you don't have the library either just click on Add library. And then that would be under sources. So let's just look for the source library source dot o lb. Click Open VDC appears. So this is a DC voltage source.

So just hit Enter on your keyboard. Click wants to place it on the schematic, right click, and then choose Add mode, or you can hit Escape on the keyboard. Next, I want to add an LED. So, I want to just select all of these libraries that I do have, in case you don't have these, click on the Add libraries button. Click once on any one of these libraries, and hit Ctrl A on your keyboard and choose Open. What this does is it adds all those libraries in that folder into this libraries section here.

Sometimes they're not all selected, so just click once on one of them. Then hit Ctrl A on your keyboard to select all the libraries. Okay, let's look for LED. Now, led shows up under the discrete library option, but I'm not sure if I can actually simulate this LED Also, sometimes the LCD option won't even appear if you don't have certain libraries available to you. So I'm going to show you how to look for a part that you don't know The part number for or don't quite know the name of go to place p spice component search. Now the P spies part search window appears.

And I want to look for an LED under the optical electronics device. expand this folder. also expand LEDs. I'm going to go with a five millimeter T one 0.75 package, choose Amber. I click once on this first option, then double click for it to attach to my cursor. Why am I going through all this?

It's because I know for sure that when I use the place P spice component option, that device can be simulated. With these other libraries, they may not necessarily be simulate a bubble, which is not a real word, but you get the idea, you may not be able to simulate those parts. So this is the method I like to go with. Right, so hit r on your keyboard to rotate it, place it right onto the resistor there, right click, choose n mode. I'm going to close this window and then add one more thing, which is a ground component here. So you can either hit g on your keyboard or click place ground on a quick access toolbar, and go with zero cap sim or zero source either one is fine, and click OK. Place it right under the LED right click Choose and mode.

Now it's time to wire the components. So click place wire and then click release to make your vertices and your connections. Alright, so just be very careful when you're connecting these components. Okay, so I made a mistake here and wire Whenever you make a mistake, just click drag and hit Delete on your keyboard. And that'll delete the extra wire. So go to File and Save your project.

Now I'm going to change the values. So for the resistor, double click on the one K, change it to 500. Hit enter for the Wii one device, or this DC voltage source, change that to nine volts DC. Click ok. I'm going to simulate this circuit out of voltage marker between the resistor and the diode here. So I'm going to place this V voltage marker right in between those components.

Just wait for it to load okay, right click and choose n mode. Now, in case you don't have this toolbar, you can just go to a p spice markers voltage level. And then this is where you can find the markers that you want. You can take a differential voltage between two circuit components or a voltage from that point to ground. So, there's a lot of options here for markers. So what this voltage probe is going to show us is the voltage between these two components with respect to ground.

And it will always do that wherever point you're placing it onto, it'll take the potential from that point to ground. Okay, so now let's set up a piece by simulation profile, go to P spice new simulation profile, and type in something like dc transia. Because we're going to show the progression of the voltage over time, click rate and click on this little window that pops up here. And this is the simulation settings and P spice. For the analysis type choose time domain. Set the runtime to one second set the maximum step size is 0.1.

Click Apply then ok Now the probe disappeared. That's interesting. Okay, so you want to make your probe markers want to place them onto the circuit after you've created your simulation profile. So let's place a probe again piece by piece, markers voltage level, right there. Okay, right click Choose and mode. Now you're ready to simulate.

We've got a p spice again, then click the Run button. And now this window shows up on the bottom. This is the P spice simulator window. Okay, the voltage remains the same over the course of one second, and it's just under two volts. Now, where is that voltage? Like I mentioned earlier, it's the voltage between this point and ground.

So there's a huge voltage drop here, seven volts from this nine volt VDC device here. Okay, it's pretty big drop, but that's fine. Now that you've simulated the circuit, I'm going to show you in the next video how to create the PCB from your LED schematic. See you in the next video.
