渔猎PCB官方视频教程：  原理图设计深入a    原理图设计深入b

1. 多页设计时的网络连接

    (1) 使用网络标识符

(2) 设置网络表示符的作用范围

    Project-->Project Options-->Options-->Net Identifier Scope

flat    – ports connect globally across all sheets throughout the design.

global  – ports and net labels connect across all sheets throughout the design.

hierarchical (sheet entry/port connections) – connect vertically between a port and the matching sheet entry.

The automatic mode automatically selects which of the three net identifier modes to use, based on the following criteria: if there are sheet entries on the top sheet, then Hierarchical is used; if there are no sheet entries, but there are ports present, then Flat is used; if there are no sheet entries and no ports, then Global is used.

2. 层次设计

    放置Sheet Symbol 的几种方法：

    (1) 工具栏快捷键

    (2)  Place-->Sheet Symbol

    (3)  右键--> Place—>Sheet Symbol

    (4)  P-->S

3. 由Sheet Symbol创建对应的原理图

    选中要创建原理图的Sheet Symbol右键--->Sheet Symbol Actions--->Create Sheet From Sheet Symbol

4. 检查Sheet Symbol Entry 与SubSheet 端口是否一致 

    Design--->Synchronize Sheet Entry and Ports

5. 自底向上进行层次设计

    由subsheet创建Sheet Symbol：右键--->Sheet Actions--->Create Sheet Symbol From Sheet Or HDL

6. 生成保持逻辑关系的原理图PDF文档

    File--->Smart PDF--->Current Project--->Choose Project File(选择包含的文件)。按向导一步一步的设置。
