Schematic Capture

Often we need to move parts or blocks of circuitry after placement and now is a good time to

cover the different ways in which we can do that. The procedure for this should be familiar to

most users; we need to select the object(s) we want to move, left depress the mouse, drag to

the new location and finally release the mouse to drop.

We can select an object in several ways as detailed below:

Choose the Selection Icon and then left click on the object. This is a standard technique

found in most graphical applications and will tag any object. Bear in mind when using this

technique that you must change back to component mode for example, when you wish to

perform other actions such as placing components etc.

Right clicking the mouse on an object will both tag the object and present a context menu

containing available actions on that object.

Draw a tagbox around the object by depressing the left mouse button and dragging the

mouse to form a box encompassing the object to be selected. This method will work for

any object (or indeed sets of objects). Sizing handles are provided to allow you to resize

the tagbox in the event that it does not fully enclose the object. This is the technique that

should be used for moving multiple, connected objects or blocks of circuitry.

We’ll get plenty of practice moving things around as we lay out the schematic; for now just use

one of these techniques to move the memory device down towards the bottom left of the Editing

Window in roughly the same position as in the screenshot at the top of the section.

Having placed the memory device, we now need to get the peripheral circuitry down and

oriented correctly. We are going to need two 10k pull up resistors and two 100 Ohm resistors for

the data and clock lines. Additionally, we are going to need to use terminals to achieve

connectivity with power, ground and other sections of circuitry. Begin by selecting the

CHIPRES10k device and click left once on the anti-clockwise Rotation icon (shown below); note

that the preview of the resistor in the Overview Window shows it rotated through 90°.
