WEBVTT 00:00.210 --> 00:06.420 So we already know that there are two types of memory that we have inside, and so if we utilize any 00:07.650 --> 00:13.640 memory that is far less than distributer memory and if we can use a dedicated memory block available, 00:13.650 --> 00:14.100 perfect. 00:14.100 --> 00:16.020 And if we do it, then they are. 00:17.550 --> 00:24.990 So let us just take an example and understand how difficult things lead to a creation of different types 00:24.990 --> 00:25.470 of memory. 00:25.870 --> 00:31.390 So there are actually two ways in which you can create different types of memory. 00:31.890 --> 00:36.720 So we looked into both the ways to try to understand each and every step in detail. 00:36.810 --> 00:41.230 So we'll see if this is the very first example that we are targeting in a memory. 00:41.550 --> 00:45.480 So I follow an entire procedure right from the beginning. 00:45.900 --> 00:47.760 So we started to create project. 00:56.450 --> 01:01.550 And then we'll probably name it as a memory to Tony. 01:02.700 --> 01:08.410 Click next, since we want to perform an entire process right from the beginning. 01:08.430 --> 01:15.240 That is from the creation of resource bill, implementation will select an active project, click next 01:16.340 --> 01:19.050 to file, see that your target languages are used. 01:19.050 --> 01:27.720 You know, we create the file will name us from memory to tell you and then will select next. 01:27.930 --> 01:30.060 Right now will not be adding any constraint. 01:30.570 --> 01:36.270 Just go ahead and board that will be using for their demonstration purposes. 01:36.270 --> 01:40.340 The next is for DIA, which have an Article seven family. 01:41.220 --> 01:43.140 So we just click finish. 01:43.150 --> 01:47.090 So this will create an workspace where we can start designing. 01:48.280 --> 01:49.600 FPGA systems. 01:53.500 --> 02:01.840 So now, very first thing that we get is the input and usually we have a certain idea related to memory. 02:01.870 --> 02:08.290 So, for example, if you are targeting a single photograph, so you have a single address, but a single 02:08.290 --> 02:14.680 database where he'll be writing a data and one other database very, very devoted, and then there are 02:14.680 --> 02:20.590 some controlled inputs or depending on the architecture or the type of memory that you're targeting, 02:20.710 --> 02:22.180 the number of things may vary. 02:22.840 --> 02:27.580 So usually you do not have an idea of all the votes. 02:28.360 --> 02:30.240 Just add the poor section. 02:30.280 --> 02:32.840 So, for example, will always be there. 02:32.860 --> 02:39.230 It doesn't decide whether Outram will be distributed or block. 02:40.490 --> 02:45.180 And along with this, I know that I'll be targeting one in six to the data. 02:45.190 --> 02:53.560 So I just select the direction as in and four to 16, which will check disperse option and will go from 02:53.560 --> 02:54.010 15. 02:54.580 --> 03:02.500 Similarly, I know that there will be a one bus from where I'll be reading Lolita Directions and then 03:02.650 --> 03:04.210 probably 15 down to zero. 03:04.210 --> 03:04.440 Right. 03:04.480 --> 03:06.610 So those are the boards that I know. 03:07.340 --> 03:11.830 Now let's assume that we are targeting one in block memory. 03:12.160 --> 03:18.580 So a particular style of vision is required to actually to block memory. 03:18.590 --> 03:21.220 I know since we do not know what is at stake. 03:21.580 --> 03:26.800 So a language template option that you have enough to navigate that is a handy option. 03:27.040 --> 03:35.050 So what we'll do is we'll just delete this comment first so that code becomes a bit easier to handle. 03:35.230 --> 03:43.510 OK, and then we'll probably include unsane library, some standard and the school logic underscore 03:43.510 --> 03:44.230 unsigned. 03:46.290 --> 03:48.640 And then will the rest of the cards. 03:49.440 --> 03:59.900 So those are the votes, that block will be a single bit and that action will win and it's 16 right 04:00.150 --> 04:00.420 now. 04:00.420 --> 04:03.930 Let us assume that we will be working on and block traffic. 04:04.110 --> 04:07.580 So we want to implement this kind of memory card. 04:07.620 --> 04:13.610 We want to have a program that is being implemented with the help of but available. 04:15.380 --> 04:20.280 So I just go through a language right now is be for all the language. 04:20.280 --> 04:27.810 It consists of various types of constructs that will lead to certain kind of districts. 04:27.840 --> 04:34.720 So instead of looking for each and every folder, what will be doing is since we want to implement that, 04:34.800 --> 04:39.030 then with a block memory, I just search for a block. 04:40.550 --> 04:47.580 So I just search for a block, so now it will basically give us a radius wherever it finds a block, 04:47.630 --> 04:52.170 so we will not be targeting one very so just minimize the very long hold. 04:52.400 --> 04:58.110 And then probably in an ideal, you have something called as an designed example. 04:58.130 --> 05:04.400 So if we just go through and then bad options that have been looted after the search, you'll be finding 05:04.730 --> 05:08.160 you have a folder that is named dozen of. 05:09.060 --> 05:10.560 A design example. 05:12.640 --> 05:16.890 So I just flew into a holding example right here. 05:16.940 --> 05:25.960 I have an example followed and then inside this, we want to have a single program, a single program, 05:25.960 --> 05:27.790 and then I can have. 05:29.100 --> 05:30.280 Different kinds of mood. 05:30.540 --> 05:34.030 So they're just looking to single photograph. 05:34.300 --> 05:43.560 Right, so no, for here you can analyze actually a structure how and when your forearm will be considered 05:43.560 --> 05:44.110 as a block. 05:44.370 --> 05:44.690 Right. 05:44.780 --> 05:47.400 So is just looked at in a typical example. 05:47.790 --> 05:52.560 So here you'll be finding you need to make an entire circuit secretion. 05:52.560 --> 06:00.090 So process you have a clock then for each of your clock we can use this kind of a Syntex. 06:00.540 --> 06:10.800 Then if in level eight is one, then if right and there is one then the data has been assigned to a 06:11.280 --> 06:18.300 memory that is being created and else will be reading it. 06:19.050 --> 06:21.960 So this is a typical format that is included here. 06:22.230 --> 06:27.770 So if you don't understand this, what you can do is you can look for other other examples if you have. 06:27.780 --> 06:36.060 So for example, it is just going to a simple developer and inside this, if we just analyze the format. 06:37.370 --> 06:46.940 So now you can look into a typical for so long and this is it, I think a clock so right. 06:46.940 --> 06:50.750 And even if we just choose the right thing and if you make it right. 06:51.390 --> 06:59.650 OK, so whatever address that you specify, whatever it is that you specified, that date will be right 07:00.350 --> 07:02.230 on that specific memory location. 07:02.630 --> 07:08.300 And if you have a dual purpose, they'll be finding you have two different addresses. 07:08.300 --> 07:15.890 And for that reason, if there will be one, you'll be simply reading a data from that specific address 07:15.890 --> 07:16.480 that is mentioned. 07:16.530 --> 07:25.370 OK, so here you can find out that these folks are on Google and Brookside equation is right in there. 07:25.580 --> 07:29.510 And secondly, if you just could do a single program. 07:33.490 --> 07:41.620 A single problem and with the with any one of this option would be finding that are thruppence that 07:41.620 --> 07:46.970 are mandatory, one is right and level and second one is E any rate. 07:47.320 --> 07:49.510 So if we make. 07:50.530 --> 07:57.550 But first, we need to make a nebulas, then only double check whether a right is one. 07:57.570 --> 08:06.090 So if that right is one of will, basically writer data and ELDs will be reading vote. 08:06.140 --> 08:11.670 So this is a typical structure that I'm trying to understand from the language. 08:12.180 --> 08:16.770 Let us just try to add the quotes in our design and try to implement that. 08:17.220 --> 08:17.520 So. 08:18.640 --> 08:26.140 And that is right, and it would have an additional often and size of single district, so this is the 08:26.140 --> 08:28.900 first thing that we have it and there is a mood for that. 08:30.190 --> 08:34.080 So let's just ignore it and enable for the time being. 08:34.090 --> 08:42.610 We know that if the level is high, we can simply put aside that specific memory location ls ls again. 08:43.570 --> 08:45.870 So this is the typical format that we are in. 08:46.570 --> 08:51.250 So it can be considered as a block and let it just ignore it. 08:51.790 --> 08:57.140 And if we perform a synthesis bill, unless actually we get to block them or not. 08:57.430 --> 09:06.510 And if you will then be able to get off of that then we'll look into the language and modify so addressed 09:06.620 --> 09:07.050 business. 09:07.210 --> 09:13.560 So we'll just have to address and let us assume that we want the death of one zero two four. 09:13.650 --> 09:23.640 So standard this code logic in the school sector and then for handling a depth of one zero to four, 09:23.650 --> 09:28.680 we require an infrastructure for declaring that then views and I don't it. 09:29.440 --> 09:35.830 OK, so this completes the remaining force that I've been missing out of an entity for a single. 09:37.030 --> 09:40.280 So we'll just now for the create a memory. 09:40.300 --> 09:44.850 So how you create a memory, it is very similar to how you create. 09:45.550 --> 09:49.680 You start with the type, you give a name to this type. 09:49.690 --> 09:57.240 So let us assume that it is having a user defined normal from when the scrutiny is and that is then 09:57.280 --> 10:01.070 that it is entity and then you define the depth. 10:01.510 --> 10:09.100 I already knew that the depth I want is one four so I can write this is I can write it as one zero two 10:09.100 --> 10:09.430 three. 10:11.490 --> 10:12.360 Down to zero. 10:13.520 --> 10:19.310 Or I can take zero to one zero two three tabooed, the methods are fine of. 10:20.240 --> 10:27.290 And then you specify the size of each element, so the size of each element that are targeting is 16 10:27.290 --> 10:27.510 bit. 10:27.530 --> 10:28.850 So we'll just ignore that. 10:30.170 --> 10:32.160 OK, so this creates an instance. 10:32.190 --> 10:35.870 Now, this instance is not usable by just ignoring a type. 10:35.870 --> 10:41.180 You need to declare a signal, a variable to use this instance. 10:41.690 --> 10:50.510 So we'll just assume it does or in fact, memory the signal and it will have a bit of an understatement. 10:50.540 --> 10:52.970 So this is how you declared a memory. 10:54.050 --> 10:56.900 Now let's just declared an architecture. 10:57.110 --> 10:58.070 So how do we do that? 10:58.350 --> 11:06.440 The first thing we need to make sense to do of so we like to process and say, OK, we'll try to follow 11:06.770 --> 11:07.810 a language template. 11:08.000 --> 11:11.600 So instead of using it, I think in fact that is also possible. 11:11.630 --> 11:22.490 Do the right thing, but will go with if it a clock event and the clock close to one, then. 11:22.910 --> 11:23.240 Right. 11:23.270 --> 11:33.680 So if given and then if, if right then it will equal to one so that indicate that you wish to perform 11:33.950 --> 11:38.890 a writing offered to a specific memory location specified Banneker's. 11:39.590 --> 11:40.790 So now. 11:41.920 --> 11:46.050 And is just so they insist that we created for the memories. 11:46.680 --> 11:50.070 Mmm, mmm, mmm. 11:50.620 --> 11:56.770 And then we need to specify the element, no order or the specific rule on which you will be writing 11:56.770 --> 11:56.830 a. 11:57.670 --> 12:00.850 And that rule will be decided on the basis of an address. 12:01.600 --> 12:10.480 So if we just add an address here and it just if you do like this and if you just end and if you look 12:10.900 --> 12:11.500 twice. 12:13.090 --> 12:21.730 OK, so we're just trying to look twice, you'll be finding choosing at a certain process since no, 12:22.630 --> 12:23.410 this isn't true. 12:24.130 --> 12:30.660 And we want to find out an element or we want to write a value to an element which must be an integer. 12:30.670 --> 12:38.620 And if you just observe either or an interest is having the type of standards for logic and descriptive. 12:38.650 --> 12:41.770 So we need to convert this to an integer. 12:41.800 --> 12:49.090 So we do that so that our function to do that, so do integer, is a function that basically convert 12:50.200 --> 12:53.680 an unsigned to and indeed so to integer. 12:53.680 --> 12:57.550 No, still it isn't either, which is a standard for logic. 12:58.570 --> 13:00.640 So what will add further is. 13:01.860 --> 13:11.220 And unsane, so first will convert a standard and logic on this convicted Lensink and then will convert 13:11.220 --> 13:14.680 that to an actual will be finding the a discount. 13:21.370 --> 13:23.480 And we'll just see, just see. 13:24.160 --> 13:31.430 So this is how you did so this operation basically signify that Baghdad, which is is changing this 13:31.440 --> 13:37.350 whole logic on just going to be converted into a say and then and saying we are going to end it. 13:37.870 --> 13:38.210 Right. 13:38.440 --> 13:44.170 So this completes an operational for writing or else else what we can do. 13:44.170 --> 13:51.790 It is the deal which is going to be simply assigning it to this thing. 13:51.790 --> 13:52.040 Right. 13:52.270 --> 13:57.480 So whatever address we specified, I mean, just try to access a memory from that. 13:58.180 --> 13:59.490 So we'll just see what it is. 14:01.030 --> 14:02.580 So this completes an entire. 14:03.820 --> 14:08.570 So very first thing that will be doing is going to be serving in our committee. 14:08.980 --> 14:13.180 So we'll just keep going until analysis and will observe a schematic. 14:13.180 --> 14:20.500 First, dad will try to understand whether on Christmas and the round block that has been created, 14:20.500 --> 14:22.120 whether they both have a seat. 14:22.930 --> 14:23.190 Right. 14:23.590 --> 14:29.020 And along with that, whether we have an extra lattice in our design, that is the second thing that 14:29.020 --> 14:29.810 we observe. 14:35.640 --> 14:39.780 We'll be finding this is an artillery round block that is being targeted. 14:39.930 --> 14:41.660 So this are all flipflop. 14:41.680 --> 14:46.710 So this doesn't create any problem for timing analysis for an art dealer. 14:46.710 --> 14:52.660 And we'll be finding anybody when I have to have a size of an order drizzles who have to say something. 14:53.070 --> 14:57.080 So the size of dress sizes matching and in fact, so much. 14:57.240 --> 15:04.730 So now we can proceed with an syntheses to actually see whether this style actually convert Arthaud 15:04.740 --> 15:06.200 into a blocked memory. 15:06.690 --> 15:10.410 OK, so here we since we are targeting honor block memory. 15:10.410 --> 15:15.110 So we have forcefully followed a state that can actually create a blocked memory. 15:15.980 --> 15:23.050 Now we will be finding this style will be different for creating a distributed. 15:23.390 --> 15:29.130 OK, so this is one of the we you go to a language template, you search for a specific component that 15:29.130 --> 15:31.800 you are targeting and then you follow a language template. 15:31.830 --> 15:37.700 So if you're exactly matches to a language template, you'll be getting an exact component to this. 15:38.080 --> 15:41.780 So we'll just see whether we actually get to block memory. 15:42.150 --> 15:44.190 So we'll just open our synthesis design. 15:45.670 --> 15:47.650 And we'll just looked into a schematic. 15:51.880 --> 15:57.700 OK, so now if you just go through a synthesis and inside a synthesis, you have a schematic, so we 15:57.700 --> 16:01.600 just go to a schematic and this is a block that has been created. 16:01.600 --> 16:03.660 And I just try to zoom in a bit. 16:03.670 --> 16:06.110 So it is basically RONNEBY. 16:07.000 --> 16:09.460 So this is a block from memory. 16:09.720 --> 16:15.430 So just to confirm this, what you can do is you can go through unfolds and inside a report you have 16:15.430 --> 16:17.130 a utilization report. 16:17.150 --> 16:23.200 So if you just go to an implementation report and the findings say duty as a memory is OK. 16:23.230 --> 16:27.040 So we have not utilized and allowed for the creation of a memory. 16:27.050 --> 16:29.260 So that is why we are getting a zero. 16:30.010 --> 16:36.340 So from this this utilization report itself, you can guess that the memory that we are utilizing is 16:36.340 --> 16:42.600 actually appropriate to be finding Block Grant, which is having a different type. 16:42.680 --> 16:44.960 So and the statistics are not in. 16:45.790 --> 16:48.280 So we are actually using one of it. 16:49.000 --> 16:54.170 So this is a typical coding style that you follow to create a block. 16:55.120 --> 17:00.130 So usually when you are working on a greater amount of depth, you. 17:01.070 --> 17:07.040 Dogged on hand, if you have a smaller debt for data, then you can target on distributed.
