WEBVTT 00:00.090 --> 00:07.290 So now we understand how we use signal and variable rate, so how we specifically assign a value to 00:07.290 --> 00:10.650 a signal and then how we view the back of value from a signal. 00:10.680 --> 00:15.780 Similarly, how we assign a value for people and then how you view the back of alright. 00:15.780 --> 00:22.380 So this will give us a fundamental set of rules that you need to follow while utilizing signal and very 00:22.390 --> 00:22.710 right. 00:22.710 --> 00:25.140 So we already have created a new project. 00:25.380 --> 00:27.320 We select the design source folder. 00:27.370 --> 00:28.050 Click on this. 00:28.350 --> 00:33.380 But right, so this gives us the window where we could specify the source code, right? 00:33.420 --> 00:39.370 So we'll just be creating and just clicking on create design tools. 00:39.390 --> 00:40.230 Click Next. 00:40.320 --> 00:43.080 OK, we haven't created a new project yet. 00:43.380 --> 00:48.040 OK, so source file is not available with this, so we'll just be creating a new source Typekit. 00:48.390 --> 00:52.430 So when you click on Read By Here, we named our file desktop. 00:52.800 --> 01:00.540 OK, and the language that we are choosing is right so that this will just finish now will assume that. 01:01.540 --> 01:07.780 They will be having an input booth of, say, scoop it and I'll pull both sides forward. 01:08.020 --> 01:14.350 So we will be first reading the data from an input poured into a signal and then we'll try to assign 01:14.350 --> 01:16.180 that value to an output. 01:16.450 --> 01:23.050 This is our agenda, so we'll be required to put one letter just as we know it is having a direction 01:23.050 --> 01:23.620 as input. 01:23.620 --> 01:30.490 And since it is of space format, we need to click on less and then the must be three. 01:30.490 --> 01:36.190 And unless we see similarly, we'll be adding y which represent our output. 01:36.960 --> 01:39.550 OK, so directions should be output again. 01:39.760 --> 01:44.640 Click on bursts and then the besides the St. Elizabeth II to zero. 01:44.860 --> 01:50.560 So in this case, this will automatically create a template for us in our designs. 01:50.910 --> 01:57.500 So right now, if you explore design source, you have a file present inside that is dark. 01:57.730 --> 01:58.810 So if you go in there. 01:59.590 --> 02:01.660 So here we have our complete OK. 02:01.660 --> 02:04.090 So I typically standalone this good logic. 02:04.100 --> 02:05.710 Or let's go one one six four. 02:05.710 --> 02:11.750 Not all is included in the source code and the reason being we are working on and standard analytical 02:11.800 --> 02:12.820 logic on this correct. 02:13.360 --> 02:15.970 So is our first input OK? 02:16.010 --> 02:17.740 And that is having this hydrophobic. 02:17.750 --> 02:18.910 So three down to zero. 02:19.300 --> 02:21.200 And then we have a semicolon, right? 02:21.200 --> 02:28.270 So semicolon indicate that we still have some of the food pending whose declaration is not yet been 02:28.270 --> 02:29.710 added to a that right. 02:30.220 --> 02:33.520 Then we declare y OK, which represent an output both. 02:33.520 --> 02:35.860 So we specify that addiction to be output. 02:35.870 --> 02:39.280 And then again, the size will be full bitrate. 02:39.310 --> 02:40.240 So three down to zero. 02:40.270 --> 02:47.810 Now remember, we is Keith's intent to do right, so it doesn't matter whether you use lowercase or 02:47.830 --> 02:48.880 not with key state. 02:49.120 --> 02:55.000 So both the word will mean the same thing right here you would really see is in lowercase, whereas 02:55.240 --> 02:57.160 is in hierarchies or here, right? 02:57.430 --> 03:01.710 But since we still is case intensive, do both mean the same thing, right? 03:01.720 --> 03:03.340 And you won't be getting any error. 03:03.610 --> 03:07.060 Now this represent our last two off declaration. 03:07.060 --> 03:08.800 We haven't specified a semicolon. 03:09.080 --> 03:09.880 This makes sense. 03:09.880 --> 03:12.930 Then we have started an entity. 03:12.940 --> 03:14.980 So here we completed are indeed. 03:15.310 --> 03:16.600 So this completes the first step. 03:16.870 --> 03:20.350 And then in an architecture, we will be hiding a logic, right? 03:20.800 --> 03:26.410 So we already know that the logic that we are planning to implement is we will be reading the value 03:26.410 --> 03:29.380 that we have on an input put in a signal. 03:29.650 --> 03:32.110 OK, and then we plan to. 03:33.350 --> 03:40.190 Saying that value on an output rate, so this is the logic that we need to add over here, right, so 03:40.400 --> 03:43.400 that it just proceed and try to declare a signal. 03:43.430 --> 03:45.590 Now remember, our input is of sites. 03:46.640 --> 03:53.750 Phobic and type standard, and this logic and disconnect a signal must also have the same type because 03:53.780 --> 03:58.560 we strongly type language, so you need to correctly work with the beta, right? 03:58.580 --> 03:59.510 So we proceed. 03:59.870 --> 04:05.360 First, we are to give our signal right, then we provide the name to our signal. 04:05.570 --> 04:07.200 So you just need me to step. 04:07.430 --> 04:14.060 OK, then Coolen, you need to specify the type that you to enable on which you want to upgrade your 04:14.060 --> 04:14.450 signal. 04:14.630 --> 04:20.120 Now, Signal do not have a detection rate, so it could be used at an input site or an output site. 04:20.420 --> 04:22.790 OK, so you need not. 04:23.790 --> 04:27.150 I had a new direction while declaring the Typekit. 04:27.390 --> 04:32.880 So if you compare this with the pooh-poohed, you need to specify the right action that signal we do 04:32.880 --> 04:34.260 not have any direction, right? 04:34.270 --> 04:37.740 So they could be utilized at an input or an output stage. 04:37.740 --> 04:46.530 So we just need to specify the Typekit so standard go logic, our Lesko vector and then three down to 04:47.280 --> 04:47.670 zero. 04:48.000 --> 04:49.060 This makes it sound. 04:49.110 --> 04:55.920 Usually when we declared a signal, we initialize it to some value, depending on the specific application 04:55.920 --> 04:56.800 that you are targeting. 04:56.820 --> 04:59.290 Now here we will be initializing it to a zero. 04:59.310 --> 05:01.860 So let me decide who equals two. 05:01.860 --> 05:09.290 And then since this is my target value, double click OK, and we will be initializing it to all seed. 05:10.080 --> 05:11.760 So this is how you declare a signal. 05:12.120 --> 05:19.920 So you need to specify the seam detailing that you are having for the food. 05:20.130 --> 05:25.230 OK, if you are utilizing the signal for that specific right, this is what we are doing here. 05:25.470 --> 05:29.770 So here we are planning to store the value of Pootie in 13. 05:29.790 --> 05:32.460 So we specify the type that is standard. 05:32.460 --> 05:36.060 And let's go logic on this vector to the test. 05:36.260 --> 05:37.560 Right now we proceed. 05:37.680 --> 05:38.010 OK. 05:39.060 --> 05:42.780 So to assign a value to a signal, the process is very simple. 05:43.000 --> 05:50.390 So we place Timbaland and we just say, right then we utilize signal assignment operator to do saying 05:50.400 --> 05:51.480 a value to a signal. 05:51.480 --> 05:55.770 We have a specific operator that we refer to as a signal assignment operator. 05:55.770 --> 05:56.430 So it is. 05:57.420 --> 05:58.660 Less than equals. 05:59.490 --> 06:05.310 This is how we represent the signal assignment operator, and then we specify an expression that we 06:05.310 --> 06:06.690 want to act with. 06:06.870 --> 06:11.520 And now here we just need to assign a value of it with them. 06:11.850 --> 06:17.110 So we'll just be adding you in the case when you are working with the complex patients. 06:17.110 --> 06:23.520 So you need to add the complex expression on an to say right now what we're going to do is this is how 06:23.520 --> 06:26.640 we assign a value to the signal. 06:26.940 --> 06:27.300 OK. 06:27.570 --> 06:31.860 The next step is how you are saying this signal to align, right? 06:32.040 --> 06:38.940 So now what we're going to do is since we already assign a value off to the temp right now, our agenda 06:38.940 --> 06:42.260 will be to assign the value of with them to the output. 06:42.270 --> 06:42.910 What right? 06:42.930 --> 06:44.370 So the process, again, very simple. 06:44.400 --> 06:45.780 So we started. 06:45.780 --> 06:47.070 Why OK? 06:47.250 --> 06:51.150 Then for our report, we again use a signal assignment operator. 06:51.150 --> 06:56.460 OK, so Signal Assignment Operator is not valid only when you are working with the variable. 06:56.460 --> 07:03.420 Investigate the cases, whether it is work or whether to signal, OK, you need to use signal assignment. 07:03.900 --> 07:04.200 Right? 07:04.220 --> 07:10.980 Remember this fact that whether it is work or whether it is signal, you need to use signal assignment 07:10.980 --> 07:16.940 operator Oleynik S. If you have a variable, you need to use variable assignment operator. 07:17.050 --> 07:17.300 Right. 07:17.310 --> 07:17.760 So why? 07:18.700 --> 07:20.550 Will be a soup day. 07:20.680 --> 07:27.540 Right, so this complete accord, no, after you complete your food, the first step is to analyze whether 07:27.540 --> 07:29.240 you get a green makeover here. 07:29.500 --> 07:33.810 So once you get the green mug that basically mean you correctly follow languished. 07:34.230 --> 07:39.630 OK, so this help us to recognize that we have a syntax error present in our right. 07:39.630 --> 07:43.970 So once we get a green indication, we should proceed and perform a simulation, right? 07:43.980 --> 07:50.550 So let me just see why I would go back to our viability date and in the simulation. 07:50.550 --> 07:55.190 So if you do not Atticus Finch automatically, the design source will be added red. 07:55.200 --> 08:01.560 So you could just go ahead and perform a simulation of it right by adding a manual stimuli. 08:01.860 --> 08:05.790 So let's just go ahead and perform behavioral simulation. 08:07.070 --> 08:14.960 So if you analyze we have three signals United in, they'll be forming the right, so you have an input 08:14.960 --> 08:19.260 will be you have an output y and then you also have a signal, right? 08:19.280 --> 08:23.350 So let me just add some random value to a variable rate. 08:23.360 --> 08:27.050 So select the input, put right click OK. 08:27.050 --> 08:29.200 And then you have a full sequence, right? 08:29.210 --> 08:31.220 So just specify the value. 08:31.220 --> 08:34.890 No, by default, the value that you specify is an hexadecimal format. 08:35.180 --> 08:38.420 We could just click on this and then we select the binary. 08:38.660 --> 08:42.590 Whatever value that you specify will be applied to an input. 08:43.250 --> 08:47.520 So let me just add one zero zero one right and click, OK, right? 08:47.580 --> 08:52.640 So once you add a value, the next step is to execute the simulation, right? 08:52.640 --> 08:59.470 So this will basically apply the stimulus that we have added to people who are raising right so that 08:59.480 --> 09:03.950 it just click on this run four thousand nanosecond rate. 09:03.950 --> 09:05.520 So we just click on this button. 09:05.540 --> 09:09.380 Now you could see, OK, right, if I zoom in a bit. 09:09.590 --> 09:10.070 So. 09:11.340 --> 09:17.670 So you could clearly observe whatever value that we have on and put the same value you have for the 09:17.670 --> 09:20.640 signal and the symbol you would get on it output. 09:20.900 --> 09:21.140 Right. 09:21.150 --> 09:26.580 So this basically indicates that we correctly able to utilize the signal, right? 09:26.580 --> 09:27.740 So to change that. 09:27.960 --> 09:29.120 The process is very simple. 09:29.130 --> 09:33.630 Just select the bus, right click and then you get an option to select, right? 09:34.080 --> 09:41.170 So here you could just choose to work on the data and then you could get a display of full value in 09:41.170 --> 09:42.390 the binary form, right? 09:42.420 --> 09:45.360 So this is how we assign a value to a segment. 09:45.630 --> 09:50.790 Remember, whether it is food or a signal you will be utilizing signal assignment operator.
