WEBVTT 00:00.060 --> 00:05.840 So let us try to understand how we use a signal, so we will be focusing again on the two areas, how 00:05.910 --> 00:12.030 we I didn't value to a variable and how you read from lady right to the first magnitude thing when you 00:12.030 --> 00:15.240 work with over evil is you need to have a process, right? 00:15.570 --> 00:18.480 So for that process, variable will be local, right? 00:18.480 --> 00:20.340 So they just need my processor speed. 00:20.680 --> 00:20.970 OK? 00:21.330 --> 00:23.200 And then we added processing. 00:23.460 --> 00:26.060 Now what process do you envisage, Dennis? 00:26.190 --> 00:31.980 For example, if you have a combination of so great, so your output will depend primarily on all the 00:31.980 --> 00:32.640 inputs rate. 00:32.850 --> 00:38.190 And when we consider the sequential circuits, so your output depends on the clock, that is, your 00:38.190 --> 00:42.480 output will be evaluated whenever we have to change in a clock each, right? 00:42.930 --> 00:48.510 So process defines when your output should be evaluated based. 00:48.510 --> 00:52.950 So then we write code like this data process. 00:53.550 --> 01:00.120 That basically mean as soon as we have a change in the value of V, so whatever expression that you 01:00.120 --> 01:03.390 specify inside the process will be evaluated. 01:03.410 --> 01:05.760 Look at and we see the changes in an outbreak. 01:06.360 --> 01:10.890 So we will be discussing more of the process as we progress to behave in more. 01:10.890 --> 01:12.810 Let's say only thing to remember is. 01:13.230 --> 01:18.150 So if you have multiple inputs present in the air, we still call. 01:18.300 --> 01:20.990 And if you circuit is combination is so great. 01:21.030 --> 01:24.900 In that case, we will be adding all the input in the process. 01:25.710 --> 01:31.050 Whenever you are working with the sequence circuit, so you will be adding the clock in the process, 01:31.050 --> 01:31.350 right? 01:31.650 --> 01:40.950 And that process basically define on what signal your expression should be evaluated that the expression 01:40.950 --> 01:42.310 that you mentioned in the process. 01:42.540 --> 01:42.840 Right. 01:43.200 --> 01:44.490 Then we have a begin, right? 01:44.490 --> 01:50.610 So we already know that between processes and begin, we have a space where we will be declaring a variable 01:50.610 --> 01:52.080 rate to proceed with. 01:52.080 --> 01:54.450 The very people will be naming the system. 01:54.470 --> 01:58.800 And now since we want to store the value of any number. 01:59.370 --> 02:05.210 So we need to again add the same data that we have for our right to standard. 02:05.480 --> 02:06.710 And let's go vector. 02:07.290 --> 02:14.930 Again, variable do not have any direction, right, similar to what we discussed with the signals, 02:14.960 --> 02:15.270 right? 02:15.600 --> 02:19.800 So standard analytical logic on Niseko Vector and then three down to zero rate. 02:19.800 --> 02:25.980 So this is exactly what the data type that we have for the pootie right, because we want this to the 02:26.310 --> 02:33.240 ordinary down to a variable rate, then we could use Kalinic was to agree to initialize this to the 02:33.240 --> 02:34.160 value that we want. 02:34.170 --> 02:35.910 So let it just try to know why. 02:35.910 --> 02:41.550 Double code, because we have multiple value vector level cooked and then food zeba. 02:41.820 --> 02:44.070 So this will initialize them to us. 02:44.340 --> 02:50.310 Then as we start the process, we know that anything we start navigation, we must integrate. 02:50.310 --> 02:56.250 So before writing a logic that it just stay in the process right now in between, we will be adding 02:56.250 --> 02:56.910 a logic, right? 02:57.180 --> 03:01.680 So let us try to assign the value of each to a template. 03:01.710 --> 03:02.490 So we start with the. 03:03.270 --> 03:06.240 Then we use a variable assignment operator. 03:06.330 --> 03:12.570 So whenever you want to assign a value to a variable, you need to use a variable assignment operator, 03:12.570 --> 03:12.760 right? 03:12.780 --> 03:15.630 So variable assignment operator, they should like this. 03:15.630 --> 03:18.030 You have a pool and equals to rate. 03:18.060 --> 03:21.840 This is not what we did in Signal, right? 03:21.850 --> 03:22.710 So far, Signal. 03:22.710 --> 03:29.750 We need to use signal assignment of data and for a very but we need to use a variable assignment operator, 03:29.820 --> 03:30.090 right? 03:30.900 --> 03:32.430 Then we add an expression. 03:32.430 --> 03:35.850 So in this case, an expression is simple variable rate. 03:36.090 --> 03:38.370 So this completes the logic that we want to add. 03:38.600 --> 03:43.560 Now we want to connect the value that we have on a team to a one. 03:43.860 --> 03:49.360 So you already know that we could not use them outside the process, right? 03:49.380 --> 03:56.250 So if you are in a situation where you want to use the value of a temp, you are saying it to an output 03:56.250 --> 03:56.850 both OK. 03:56.850 --> 04:01.320 And that is, you need to specify an output inside the process, right? 04:01.560 --> 04:06.450 So here, just below it will be adding a way now for a port, a signal. 04:06.450 --> 04:10.110 We already know that the type of assignment operator that we're going to use this. 04:11.150 --> 04:17.670 Signal assimilate, so it just really signal assignment operator and then the tip. 04:17.810 --> 04:18.060 Right. 04:18.680 --> 04:25.520 So this is how you connect variable to the right to remember them is valid only in a process block. 04:25.760 --> 04:30.500 So if you want to connect them to any of the signals are appalled. 04:30.800 --> 04:32.990 So you need to utilize it in the process. 04:33.200 --> 04:34.250 So this complete call? 04:34.520 --> 04:40.550 So some of the key points that you need to remember is and must have the same tape that you have for 04:40.550 --> 04:43.070 a boot, which you want to provide, right? 04:43.070 --> 04:51.060 So if if you want to do the value of inside the tape, so it should have a scene tape that I would have 04:51.110 --> 04:57.560 right then to assign a value to an variable, we need to use our variable assignment operator right? 04:57.560 --> 05:00.530 So far, a signal line, a good signal assignment operator. 05:00.530 --> 05:04.070 We're just fine for the variable. 05:04.350 --> 05:06.840 OK, you need to use variable assignment operator now. 05:06.890 --> 05:12.440 If you just replace this with the signal assignment operator, you'll immediately see. 05:14.060 --> 05:18.470 Edit, if you try to perform an analysis, let me just see this here. 05:18.740 --> 05:22.790 You could see we do not get any real indication. 05:23.060 --> 05:23.390 OK. 05:23.510 --> 05:29.630 But if you just try to go ahead lyricism to an ideal analysis and try to open a schematic, let me just 05:29.630 --> 05:30.400 click on look. 05:31.900 --> 05:33.750 So you could see now we start to see. 05:34.230 --> 05:34.530 Right. 05:34.800 --> 05:39.830 And there it is, use who was to do a saying the lady was right. 05:39.840 --> 05:45.210 So remember this variable assignment operator you need to use if you are lucky with them? 05:45.580 --> 05:45.780 Right. 05:45.780 --> 05:50.440 So we'll just be changing this back to the variable assignment operator. 05:50.490 --> 05:53.060 We'll see what we go back to. 05:53.400 --> 05:57.300 I would like to do right now here we have our existing simulation, right? 05:57.300 --> 06:00.280 So we're going to just close an existing simulation. 06:00.300 --> 06:04.860 OK, it's a good idea could be that you close the simulation tab that you see. 06:04.890 --> 06:05.490 All right. 06:05.490 --> 06:08.220 So we'll just be closing the simulation loop. 06:08.220 --> 06:14.160 And if you want to store the window, we will form information, OK, you could just save it or else 06:14.160 --> 06:15.450 we could just discard it, right? 06:15.480 --> 06:18.390 We do not need to use the flow of information. 06:19.230 --> 06:23.250 Now we proceed for a gain performing a behavioral simulation. 06:24.590 --> 06:25.040 Now. 06:26.500 --> 06:30.520 So let me just try to assign a value to we will be right, so right click. 06:31.500 --> 06:37.590 What's continuing and will be utilizing the value in the binary format, the one zero one one click, 06:37.590 --> 06:37.980 OK. 06:38.100 --> 06:43.390 And let me just try to execute that right now you will see both our bus have a scene, right? 06:43.530 --> 06:43.770 Right. 06:43.770 --> 06:46.440 So we actually able to utilize the video. 06:46.440 --> 06:56.350 But OK, inside right now we have a duel to use to store the temporary data from what we need across 06:56.760 --> 06:57.330 the signal. 06:57.540 --> 07:03.570 Or we could prosecute the very, very signal have a global scope while the video will have the local 07:03.570 --> 07:03.810 school.
