00.01 | Dear Friends, |
00.03 | Welcome to the spoken tutorial on Electric rule check and netlist generation in KiCad |
00.09 | In this tutorial, we will learn |
00.12 | To assign values to components |
00.14 | To perform electric rule check. |
00.17 | And to generate netlist for schematic created |
00.21 | We are using Ubuntu 12.04 as the operating system . |
00.25 | With KiCad version 2011 hyphen 05 hyphen 25 for this tutorial. |
00.33 | Basic knowledge of electronic circuit is a pre-requisite for this tutorial. |
00.38 | User should also know how to design circuit schematic in KiCad |
00.42 | For relevant tutorials, please visit the link spoken hyphen tutorial.org
|
00.49 | To start KiCad, |
00.50 | Go to top left corner of ubuntu desktop screen. |
00.56 | Click on the first icon i.e, Dash home. |
01.01 | In the search tab write KiCad and press Enter |
01.10 | This will open the KiCad main window |
01.13 | Click on EEschema tab. |
01.17 | An Info dialog box appears saying it cannot find schematic. |
01.21 | Click on OK. |
01.23 | We will use the file project1.sch created earlier. |
01.29 | Go to File menu and click on Open. |
01.33 | Select project1.sch from desired directory. |
01.44 | We will now assign values to components.
|
01.49 | Let us assign value to R2 component. |
01.54 | Keep cursor over R, corresponding to R2 resistor. |
02.01 | Right click and choose Field value |
02.05 | This will open Edit value field window. |
02.11 | Type 1M and click on OK. |
02.17 | As you can see 1M (i.e., 1 mega ohm) value is assigned to the resistor R2. |
02.24 | I have already assigned values to other components in the similar way. |
02.29 | Next step is to perform electric rule check on this circuit |
02.36 | Go to top panel of EEschema window. |
02.39 | Click on Perform Electric Rule Check button. |
02.44 | This will open the EEschema Erc window. |
02.48 | Click on Test Erc button. |
02.52 | We can see that there are two errors. |
02.56 | Both errors say that the terminals have no power sources. |
03.00 | Click on the Close button. |
03.03 | In the schematic, the error nodes are pointed by arrows. |
03.12 | Let us connect a power Flag here. So then kicad will know that we are going to connect a power supply here. |
03.22 | For this, |
03.24 | On the right panel, click on Place a power port button. |
03.28 | Now click on the EEschema window to open the component selection window. |
03.34 | Click on List All button and you can see list of power notations. |
03.40 | Choose PWR_FLAG and click on Ok. |
03.49 | We will place the PWR_FLAG near Vcc terminal. |
03.55 | Click on the EEschema to place it. |
03.59 | We need two such power flags since there are two errors of such type. |
04.05 | Keep the cursor on the power flag and then press c to copy it. |
04.10 | Place this power flag near the ground terminal. |
04.15 | Now we will connect the power flag with wires. Go to right panel and click place a wire button. |
04.24 | Now connect the power flag to VCC terminal |
04.35 | Similarly connect the power flag to the ground terminal |
04.44 | We will now run the Schematic ERC check once again to confirm. |
04.49 | For this, click on the Perform Electric Rules Check on the top panel of EEschema window. |
04.55 | This will open the EEschema Erc window. |
04.58 | Click on Test Erc button. |
05.01 | We can see that there are no errors. |
05.04 | Click on Close |
05.07 | Now let us see how to generate netlist. |
05.10 | Netlist gives information about list of components and nodes that connects them together. |
05.16 | We will see the use of netlist as we proceed further in this tutorial. |
05.20 | For generating netlist, go to the top panel. Click on netlist generation button. |
05.27 | This will open up the Netlist window. |
05.31 | This window contains tabs which allow you to generate netlist in different formats. |
05.38 | For kicad we will use Pcbnew tab. |
05.42 | Keep Default format option checked and click on Netlist button. |
05.48 | Note that it saves the netlist file with name project1.net |
05.54 | Please note that when the netlist is generated, the file is saved with .net extension. |
06.00 | Click on the Save button. |
06.02 | Let me resize the window. |
06.04 | Click on the Save button. |
06.06 | Netlist file contains information about components in the circuit required for printed circuit board design. |
06.14 | We will see the use of this netlist file in another tutorial. |
06.20 | Go to File menu and choose Save Whole Schematic Project to save this schematic.
|
06.27 | Go to File menu and choose Quit to close EEschema window |
06.32 | In KiCad main window, |
06.34 | Go to File menu and choose Quit. This will close the KiCad main window. |
06.40 | In this tutorial we learnt, |
06.44 | To assign values to components |
06.46 | To check and correct for errors in circuit schematic |
06.50 | To generate netlist for circuit. |
