WEBVTT 00:00.060 --> 00:05.940 So let us consider a very first example where we plan to implement the full weight in half. 00:06.320 --> 00:12.210 OK, so the tagline for a structurally modeling style is whenever we are using our own company logo. 00:12.230 --> 00:21.060 So here what we assume is the halflings, we are previously utilizing a simple visual code and then 00:21.060 --> 00:29.010 we are trying to use an idea to build a full ad and whenever we try to reuse our own components. 00:29.070 --> 00:32.700 OK, in that case, we them the modeling side to be a structural model. 00:33.180 --> 00:42.180 OK, so if you see for a full ad, OK, in an entity will be declaring A, B and C which are of size 00:42.180 --> 00:42.570 single. 00:42.930 --> 00:48.630 So this will be our input and we have some and which will be around. 00:49.470 --> 00:50.290 This makes sense. 00:50.300 --> 00:55.230 So for a holiday we have three inputs each of size, single with A, B and C. 00:57.290 --> 01:03.000 So A, B and C will have a direction of ending and some inquiry will have a direction of an outbreak 01:03.010 --> 01:07.940 right now these are the food or the need for a net, which we already defined in. 01:07.940 --> 01:09.690 And indeed, this makes sense. 01:09.710 --> 01:12.220 So this will be declaring an identity. 01:12.590 --> 01:17.120 And if you observe that this this will already be declared in an entity. 01:20.190 --> 01:25.530 Similarly, this Senate will also be declaring an entity and the Senate will also be declared an entity. 01:26.160 --> 01:32.280 So if I just try to mark the net, which are defining an entity, so we have this net. 01:32.820 --> 01:34.280 We have this net, right. 01:34.710 --> 01:38.920 We also have this net being already declared in an entity. 01:39.450 --> 01:41.390 We also have declared an output pool. 01:41.900 --> 01:44.200 So this net are already declared. 01:44.740 --> 01:47.370 OK, so if you just. 01:49.120 --> 01:56.490 Find out that beside the net that we have defined, they do exist, some of which are not defined in 01:56.530 --> 01:57.130 an entity. 01:57.280 --> 02:02.200 OK, so this net will be referring to as an undefined net. 02:04.060 --> 02:10.780 So this will be referring to as an undefined net and the nets, which are defined inside an entity, 02:11.050 --> 02:15.460 will be referring to them as defined nets. 02:17.020 --> 02:22.450 OK, so now you have a distinction between defined nature and a defined trait, so. 02:23.600 --> 02:26.270 To define or to. 02:27.470 --> 02:33.220 Declared the behavior of an undefined that an enemy is still the use signal. 02:33.260 --> 02:38.240 OK, so this is an important point to understand because you'll be frequently finding that much different 02:38.240 --> 02:43.970 component to build a single system, or when we interconnect the multiple subsystem together to build 02:43.970 --> 02:47.690 a complex system, you'll be finding that some of the nets are undefined. 02:48.770 --> 02:53.460 So to declare them in aviation code, we frequently use signal. 02:54.020 --> 02:55.190 OK, while. 02:57.030 --> 03:04.230 Doesn't it, which are defining it inside a structural inside our entire complex design will simply 03:04.620 --> 03:08.670 refer to them by the name that we have used in an antique object. 03:08.880 --> 03:12.660 So here what will assume is the undefined net over here. 03:12.670 --> 03:14.400 So I'll just use a different color. 03:14.520 --> 03:18.750 OK, so this net will be giving a name, Stephen. 03:18.810 --> 03:26.400 OK, so this net will be giving an amnesty to and let us assume that this net that we have here will 03:26.400 --> 03:27.270 be just naming it. 03:28.110 --> 03:34.440 OK, so we'll consider this example and try to write a call for it so that you have an overall picture 03:35.010 --> 03:37.450 about how you start writing a structure. 03:38.100 --> 03:38.330 Right. 03:38.610 --> 03:41.250 So first we required to build an Hafford. 03:41.280 --> 03:43.550 This is the first mandatory thing that we require. 03:43.890 --> 03:46.910 OK, and then we can proceed with then Fullard. 03:47.160 --> 03:48.670 OK, so let's get started.
