Biscuit Copy and Paste
The Biscuit Copy and Paste feature facilitates the creation of board setups for
PCBs composed of a palette of identical biscuits of circuitry. With Biscuit copy
and Paste, users create Device information for only one of the biscuits. After
that, he/she can use biscuit copy and paste to duplicate the biscuits.
For biscuits that are flipped 90 or 180 degrees, the System AOI has a special
algorithm to rotate the Device information before pasting.
Users can assign biscuit IDs to each biscuit in order to identify each Device.
Biscuit IDs precede the Device Reference IDs. For example, IC1 on biscuit 3
is denoted as 03-IC1. When pasting a biscuit, the software will prompt for a
biscuit ID. It is also possible to alter the Biscuit ID of a biscuit already pasted.
To do so, first select Edit | Select Biscuit; select the biscuit area, and then
press OK on the ROI OK/Cancel box. Then select Edit | Enter Biscuit ID to
change the biscuit ID. However, users should NOT assign biscuit ID to the
original biscuit; this is because the system automatically group all the Devices
with no biscuit prefix into a special biscuit called master biscuit. This master
biscuit makes the biscuit update function possible. During biscuit update the
rest of the biscuits are updated based on the master biscuit.
The Biscuit Copy and Paste function works with the active window concept.
You can activate a window by clicking anywhere in the window. A biscuit can
be copied from either the Map View window or the Video window. For
example, to copy a biscuit from the Map View window, make sure Map View is
the active window (if not just click on it to make it active); select Edit | Copy
from Supervisor Mode main menu. A ROI box will appear in the Map View
window to allow the selection of the region. Pressing OK on the ROI
OK/Cancel box completes the copy operation. Similarly, a biscuit may also be
copied from the video window.
Pasting can only be done in the video window. This is because the system
needs to check to see if the Devices are really there. To paste the biscuit just
copied, position the Image so that the top left corner of the biscuit appears in
the video window (if the biscuit is rotated 180 degrees, the top left corner
becomes the bottom right corner), select Edit | Paste from the main menu,
drag the overlay so that it lines up with the corresponding Devices. Press OK
on the ROI OK/Cancel box.
