protel99 画层次原理图、多part元件的绘制方法（Protel99 draw hierarchical schematic diagram, multi part component drawing method） In actual work, we may need to connect multiple schematics and draw on the same PCB file: 1., first of all, make sure that each schematic has a port (or Port) that connects to each other. The port name is the same 2. create a new SCH file or open a SCH file with enough blank space on it 3. on the selected SCH file, execute the Design - Create System From Sheet... Command, select a SCH text Piece, carriage return confirmation 4. place the generated squares in the right place 5. repeat the 3 and 4 steps until all the linked SCH files are added 6. connect each box with the same port (that is, Port) with wires 7. generate network tables on this SCH file 8. create a new PCB file and load the generated network table 2), the solution for the number of component is to achieve uniform number more than one map in Protel, first of all to multiple drawings made level principle diagram, and then click to select the menu Tools Annotate layout options, and then Current sheet only is a small hook under the Options label to fall, click OK to complete. 3) when using Protel99 to draw hierarchical schematic diagram: ERC test, if there is Duplicate Sheet Numbers, what is the error? Indicates that the sheet number is repeated. Open the SCH diagram, then press the shortcut key, D, O. In the pop-up option dialog box, click the organization tab and fill in the label in the following sheet NO.. Do not repeat it. 4), in the netlist, execute the menu command Create Netlist, if for the hierarchical principle diagram, it should be to the Append sheet number to local option on the hook, this principle can be found between the corresponding network number. 5) in Protel 99SE, with a layered method to draw a few circuit diagrams, but these drawings of the net label logo line can not even up, the logo is the same, can not even connect. In other words, set the scope of these symbols, but do
