WEBVTT 00:00:09.940 --> 00:00:12.000 Hi and welcome to the short introduction to 00:00:12.000 --> 00:00:15.240 two of the most important actions of MES Model & Refactor. 00:00:15.240 --> 00:00:18.600 Called Auto Layout and Refine Layout. 00:00:18.632 --> 00:00:23.200 With these actions you can achieve a clean and consistent layout for your models. 00:00:23.600 --> 00:00:25.920 Let's start with the Auto Layout action. 00:00:30.420 --> 00:00:32.440 With Auto Layout you can automatically 00:00:32.440 --> 00:00:36.060 arrange all blocks and route all signal lines in the current subsystem. 00:00:44.460 --> 00:00:48.120 The action arranges the blocks according to the data flow from left to right. 00:00:50.880 --> 00:00:52.560 It aligns blocks horizontally 00:00:55.020 --> 00:00:57.660 and place it them vertically 00:00:57.660 --> 00:00:59.920 to reduce line crossings and line bends. 00:00:59.940 --> 00:01:03.840 so that all signal lines can be routed as straight as possible. 00:01:08.100 --> 00:01:11.281 As a result the subsystem is easy to understand 00:01:11.555 --> 00:01:13.329 and guideline compliant. 00:01:13.353 --> 00:01:16.460 For example the data flows from left to right. 00:01:16.460 --> 00:01:19.562 Input blocks are placed on the left 00:01:19.586 --> 00:01:23.420 and output blocks are placed on the right. 00:01:23.880 --> 00:01:27.468 And all blocks have enough spacing to show signal names 00:01:27.492 --> 00:01:30.480 and block names clearly without any overlap. 00:01:33.900 --> 00:01:36.388 Documentation blocks and control port blocks 00:01:36.402 --> 00:01:38.890 are also placed in accordance to guidelines. 00:01:41.880 --> 00:01:45.112 In addition Auto layout ensures a consistent layout 00:01:45.136 --> 00:01:47.480 across all subsystems of your model, 00:01:48.060 --> 00:01:51.900 simplifying readability and maintainability of the model. 00:01:52.800 --> 00:01:54.874 Let's have a look at another example. 00:01:54.898 --> 00:01:59.480 Imagine you're working on this subsystem on a higher structural level of your model. 00:01:59.500 --> 00:02:04.720 On these higher levels you usually find large subsystem blocks 00:02:08.320 --> 00:02:14.980 and many small blocks next to the large blocks like constant or terminator blocks. 00:02:18.060 --> 00:02:20.993 Manually cleaning up the layout of such a subsystem 00:02:20.994 --> 00:02:23.800 is time consuming and tedious. 00:02:38.520 --> 00:02:42.120 With Auto Layout you can clean up the layout with just one click. 00:02:48.960 --> 00:02:51.920 Even if you have created such a clean layout manually 00:02:51.920 --> 00:02:56.920 these types of subsystems often need to be functionally adapted to new requirements. 00:03:23.100 --> 00:03:25.560 Then you need to manually clean up the layout again. 00:03:45.840 --> 00:03:49.120 Instead of wasting your time with these manual adjustments 00:03:49.120 --> 00:03:53.600 you can again use Auto Layout to correct the layout quickly and easily. 00:04:01.500 --> 00:04:04.820 Even after small changes like signal renaming 00:04:04.820 --> 00:04:08.120 you can easily update the layout to readjust the block spacing 00:04:23.100 --> 00:04:26.238 If you want to clean up only a small part of a subsystem, 00:04:26.262 --> 00:04:29.550 without changing the overall layout that you have created, 00:04:29.574 --> 00:04:32.220 you can apply the action to a selected sub area. 00:04:34.080 --> 00:04:36.660 To do this just drag the selection rectangle 00:04:39.780 --> 00:04:41.220 and then select the action. 00:04:45.420 --> 00:04:48.420 The menu entry of the action now ends with the word selection. 00:04:53.400 --> 00:04:55.644 The action then cleans up only the selected part 00:04:55.648 --> 00:04:58.200 without changing the rest of the subsystem. 00:05:00.960 --> 00:05:02.693 Here is another typical example 00:05:02.717 --> 00:05:06.420 where you may want to apply the action only to a selected sub area 00:05:08.460 --> 00:05:12.020 because you don't want to change the overall structure of your layout. 00:05:23.100 --> 00:05:26.700 You can also set custom parameters for blocks and lines with the action. 00:05:33.360 --> 00:05:35.280 For example you can color port blocks 00:05:39.180 --> 00:05:42.170 or enable signal propagation for signal lines 00:05:42.194 --> 00:05:44.160 according to your guidelines. 00:05:47.040 --> 00:05:50.480 You can simply activate the feature via the more preferences menu. 00:05:53.340 --> 00:05:56.100 Now let's have a look at the action called Refine Layout. 00:06:01.680 --> 00:06:04.990 The Refine Layout action is similar to the Auto Layout action 00:06:04.990 --> 00:06:10.240 because it also creates a clean and uniform layout for the current subsystem. 00:06:11.220 --> 00:06:13.080 However unlike Auto Layout 00:06:13.104 --> 00:06:17.440 the result of Refine Layout is based on your current layout. 00:06:25.500 --> 00:06:28.440 Now let's compare this with the result of Auto Layout. 00:06:36.480 --> 00:06:40.077 The result of Auto Layout is also clean and readable 00:06:40.101 --> 00:06:43.100 but is very different from your original layout 00:06:43.198 --> 00:06:46.120 because it doesn't take into account the initial state. 00:06:48.840 --> 00:06:51.943 So if you want to have a clean layout similar to your existing one 00:06:51.960 --> 00:06:55.740 you can use Refine Layout instead of Auto Layout. 00:07:00.540 --> 00:07:05.613 Refine Layout gives you full control over the overall layout of your subsystem. 00:07:06.700 --> 00:07:08.915 You can define the structure of the layout 00:07:08.915 --> 00:07:12.035 by roughly placing the blocks and lines where you want them. 00:07:29.680 --> 00:07:32.468 The action then preserves this structure 00:07:32.492 --> 00:07:35.440 and takes care of the remaining time-consuming tasks, 00:07:35.441 --> 00:07:38.721 such as aligning blocks and optimizing line routes. 00:07:52.700 --> 00:07:54.499 The full power of Refine Layout 00:07:54.499 --> 00:07:57.856 can be seen when you apply it multiple times in a row. 00:07:58.560 --> 00:08:02.940 So imagine you want to clean up the layout of this subsystem with a Refine Layout. 00:08:08.460 --> 00:08:12.440 The result looks like this because it is similar to the original layout. 00:08:13.620 --> 00:08:15.883 Now if you're not satisfied with the result 00:08:15.907 --> 00:08:18.540 you can just roughly adjust the layout as you wish. 00:08:19.250 --> 00:08:22.190 For example you may want the conversion blocks here 00:08:26.160 --> 00:08:28.600 and the smaller blocks here. 00:08:30.540 --> 00:08:32.160 Then just restart the action. 00:08:36.720 --> 00:08:41.198 Maybe you're still not satisfied because you would like to have these blocks here 00:08:41.422 --> 00:08:42.940 further to the left. 00:08:46.740 --> 00:08:49.380 Then just move them and restart the action. 00:08:53.100 --> 00:08:57.660 This way you can optimize the layout step by step until it meets your demands. 00:09:00.300 --> 00:09:03.850 In the same way you can also optimize the line routing 00:09:03.850 --> 00:09:06.600 if you are not satisfied with the initial result. 00:09:27.180 --> 00:09:29.640 Refine Layout is also very convenient 00:09:29.640 --> 00:09:33.380 to update the layout after you have changed your subsystem manually. 00:09:34.440 --> 00:09:36.608 So imagine you're working on this subsystem 00:09:36.632 --> 00:09:38.900 and you add a new signal line and a new block. 00:09:52.140 --> 00:09:56.040 If you use Auto Layout the result may look quite different than before 00:09:56.040 --> 00:09:57.604 because of the new elements. 00:10:09.480 --> 00:10:12.195 So if you just want to update the layout gradually 00:10:12.219 --> 00:10:13.512 and keep it similar to before 00:10:13.536 --> 00:10:16.579 Refine Layout can do just that for you. 00:10:24.600 --> 00:10:30.000 As with Auto Layout you can also use Refine Layout to set custom parameters 00:10:30.000 --> 00:10:34.380 for blocks and lines such as block colors or signal label propagation
