WEBVTT 00:00.450 --> 00:03.510 Let's try to use the different right that we discussed. 00:03.660 --> 00:10.950 So first, we whenever we have a situation where we want to declare a port give that is capable of handling 00:10.950 --> 00:19.720 a single bit value, which would either be input or an output benefit is, let's assume, named Daisy. 00:20.130 --> 00:20.480 OK. 00:20.580 --> 00:25.160 And if it is important, we will be adding a direction and then we just don't have it right. 00:25.170 --> 00:29.570 So this is how we declared the single bit port. 00:30.270 --> 00:30.540 Right. 00:30.540 --> 00:32.370 So that is having an addition of an input. 00:32.750 --> 00:38.550 And whenever we are in a situation where we want to declare the put off and output direction, in that 00:38.550 --> 00:45.300 case, that is a damages b that we specify that action is out and then the only difference between standard 00:45.300 --> 00:49.500 and logic of Britain's biggest capable of handling zero. 00:50.000 --> 00:50.170 Right. 00:50.180 --> 00:54.450 So we could not have other logical levels assigned to a great. 00:54.780 --> 00:56.490 So do I recommend an invasion? 00:56.490 --> 00:57.810 Envisioning the process is very simple. 00:57.810 --> 01:01.230 You just need to do that and then you can start adding a comic, right? 01:01.230 --> 01:06.180 So there is nothing like a multi-lane committee in Abuja, but you get this option. 01:06.180 --> 01:06.920 We're here, right? 01:06.930 --> 01:12.240 So here I have come into all the three lines you need to add the two dashes for all the light. 01:12.660 --> 01:15.360 But if you select all the light again, click on this button. 01:15.360 --> 01:18.330 So this will automatically uncomment the multiple light. 01:19.050 --> 01:23.280 And similarly, if you want to come into multiple light, you just need to select multiple line and 01:23.280 --> 01:24.360 click on this one, right? 01:24.390 --> 01:27.710 This will automatically add to Dash to all the lights. 01:29.270 --> 01:36.440 So an important point to remember about protests it is capable of handling zero or one only to logic 01:36.450 --> 01:41.410 levels are defined for a bit and for that, we do not need to declare any library, right? 01:41.420 --> 01:48.350 So here you could clearly see we have come out all those statements that help us to include the library 01:48.350 --> 01:49.980 and then great. 01:50.420 --> 01:52.520 So this is how we declared the date. 01:52.880 --> 01:56.690 Now, if you want to use the mighty bit. 01:57.790 --> 02:03.820 But, OK, that is capable of handling only zero or well in that case, we proceed like this. 02:03.830 --> 02:05.050 So that is it, you see? 02:05.270 --> 02:07.420 OK, so that would be Input-Output. 02:07.480 --> 02:09.310 Let me just focus on an in between. 02:09.820 --> 02:13.410 Then we are a bit OK and school victim, right? 02:13.420 --> 02:16.320 So this is how we declared a multiple bus. 02:16.330 --> 02:21.150 And then when you specify a vector, you need to also specify the size, right? 02:21.160 --> 02:21.830 So for our food. 02:22.510 --> 02:25.030 The size will be three down to seed. 02:25.210 --> 02:25.570 Right? 02:26.560 --> 02:32.560 If you want to go in a descending order and in most of the cases when we work with the board, we followed 02:32.570 --> 02:33.230 descending on that. 02:33.250 --> 02:35.470 There is an alternative for this also. 02:35.980 --> 02:39.980 So you could also use an ascending order to specify the food site. 02:40.000 --> 02:41.980 It will be from zero to three, right? 02:42.340 --> 02:47.740 So either you will use three down to zero that is also valid or you could also use zero two three. 02:48.010 --> 02:52.450 So what is the other way of specifying the food size, right? 02:52.450 --> 02:58.200 So you will either use three down to zero or zero down with both mean the same thing, right? 02:58.570 --> 03:04.060 Though in most of the cases, while we are working with the code, we will be utilizing three down to 03:04.060 --> 03:04.480 see you. 03:04.530 --> 03:04.800 Right. 03:04.810 --> 03:10.410 So this is how we declared the multi bit bus, which is capable of and gets 0.1, right? 03:10.420 --> 03:11.380 So bit. 03:12.480 --> 03:18.870 Can handle zero on one big vector, can again handle zero and what, but it gives us a capability to 03:19.050 --> 03:22.750 tour or to work around with multiple bus, right? 03:24.080 --> 03:27.230 Then we have a Boolean, so boolean we never used in a boat. 03:27.320 --> 03:30.710 We always utilize them in conditional, efficient. 03:31.010 --> 03:32.180 Then we have an integer. 03:32.180 --> 03:36.440 So most of the cases integer is used as a counter variable rate. 03:36.440 --> 03:42.740 So whenever we are generating a delay or generating our own countersue, integer is utilised so you 03:42.740 --> 03:44.730 rarely find them in right. 03:45.110 --> 03:47.900 So these are frequently utilized in signal, right? 03:47.900 --> 03:51.410 So let me just try to understand how we utilize Tamminen signal, right? 03:51.830 --> 03:56.660 So we proceed with the signal now to declare a signal of Typekit. 03:56.780 --> 03:58.430 So let me just name this estimate. 03:59.000 --> 04:01.400 Then calling the type is a bit. 04:01.640 --> 04:08.210 OK, and then we need to specify an initialization run rate to hoola equals two and to initialize the 04:08.210 --> 04:09.540 time to a value of zero. 04:09.560 --> 04:12.580 We need to have single code and then see, right. 04:12.590 --> 04:15.590 So this is how we declared a variable temp. 04:15.730 --> 04:19.610 OK, that is of Typekit and initialized to a value of C. 04:19.760 --> 04:20.030 Right. 04:20.450 --> 04:25.040 So but you need to add a single rate for an initialization, right? 04:25.500 --> 04:31.760 Then if you want to initialize them to a value of one again single code and then you specify the value, 04:31.820 --> 04:32.090 right? 04:32.480 --> 04:39.020 Similarly, if you consider this is you have a temporary value, but which you want to use to store 04:39.200 --> 04:40.480 the multiplied value, right? 04:40.520 --> 04:41.090 So signal. 04:42.190 --> 04:43.030 Team two. 04:43.390 --> 04:43.750 OK. 04:43.990 --> 04:46.960 This is the name that we have provided to our variable Dan. 04:47.370 --> 04:52.810 Let's assume it is capable of handling bit values a bit on this goal vector. 04:53.350 --> 04:56.830 OK, then we specify the size of three down to zero. 04:57.190 --> 05:02.190 Then we are golden equals two who can do assign value to it whenever you want. 05:02.200 --> 05:03.360 The item will give it value. 05:03.430 --> 05:05.220 You need to use double, right? 05:05.440 --> 05:11.590 So for a single bit value, you'll need to single quote and for multiple value, we need to use double. 05:11.800 --> 05:12.100 Great. 05:12.100 --> 05:15.700 So here we're just batting zero zero zero zero. 05:16.370 --> 05:21.160 OK, so this will initialize all the bit that we have in the bus to let's see, right? 05:21.160 --> 05:26.290 So this is how you add a bit vector then to declare the variable of Boolean type. 05:26.300 --> 05:30.400 So signal that I just need this as temp. 05:31.230 --> 05:35.940 To OK to our regulars will just be mentioning bullying over here. 05:36.010 --> 05:37.560 Now this could take two values, right? 05:37.570 --> 05:39.330 They could either be a true or false. 05:39.600 --> 05:40.130 So cool. 05:40.830 --> 05:44.730 And then we will be initializing it to a value of truth. 05:44.820 --> 05:49.920 OK, so you would also add a false here, right, to declare an integer. 05:49.930 --> 05:51.930 So we start with the signal. 05:52.070 --> 05:57.050 Let's just name this as STEM three again, colon integer, right? 05:57.720 --> 06:02.670 And then we specify the initialization value that is as you see, right? 06:02.670 --> 06:08.130 So we already knew that this could take from minus two rows to 32 by two to two days to 32 by right? 06:10.230 --> 06:16.890 So the value that are integer, it ranges from minus two one four seven four eight three six four eight 06:17.250 --> 06:21.000 two plus two one four two seven four eight three six four. 06:21.090 --> 06:21.250 Right. 06:21.270 --> 06:24.910 So this is equal to two days to 32 by two. 06:25.020 --> 06:25.280 Right. 06:25.290 --> 06:29.100 So this is the value that is allowed to be utilized with an integer. 06:30.730 --> 06:31.810 Now the other way around. 06:31.920 --> 06:38.290 OK, whenever we are working with an linkages and if we want to restrict the size of an hardware that 06:38.290 --> 06:40.410 is been utilized to build up an integer. 06:40.810 --> 06:45.130 So we often utilize a user defined range for an integer, right? 06:45.160 --> 06:50.770 So how we do that, for example, we know that M3 equal to values only from zero to 100. 06:51.060 --> 06:58.150 OK, so instead of creating a big heart rate, we will just mentioned integer range zero to 100. 06:58.190 --> 06:58.420 Right. 06:58.420 --> 07:03.550 So this is not specifying that we have a valid values from zero to 100. 07:03.790 --> 07:05.590 Then we can initialize this with zero. 07:05.590 --> 07:08.080 So this helps to reduce the size of and hardware. 07:08.080 --> 07:13.090 When we see today is this demo three to an actual heart rate. 07:13.540 --> 07:18.880 So we could either add an integer, so that would give you the maximum size that integer could hold 07:19.060 --> 07:20.860 or you would just use reach. 07:20.870 --> 07:25.840 You can specify the valid range that you are expected expecting for an integer. 07:26.110 --> 07:30.430 OK, so this is how we use or declared the building Typekit. 07:30.550 --> 07:35.500 So we have a bit which could be used to handle zero and win right. 07:36.130 --> 07:40.200 Then we have a bit vector, which could be used to handle against the value of two. 07:40.210 --> 07:47.080 And but with the multi bit bus, then we have a Boolean which is capable of handling two and false and 07:47.080 --> 07:48.670 then we have an integer, right?
