Have a look through the [View] and [Settings] menu entries to see what has been set up. In the full. Technology file can also be created from a design. This has the benefit that it can also contain the board. How many ways do you. The automatic assignment of the net classes to the net names in the same way as in the originating design.
Note that all of the parameters set up by Technology files can be changed at any stage throughout the. Technology files are there to help you and speed the design process not manacle you or.
Easy - PC assumes that you want to continue. Each of the gates can now be selected and moved individually. Temporarily unused gates should be. If subsequently not. Repeat this process to add a couple more components from other libraries. If you put down discrete. Each connection can be given a Net Name and have a Net Class allocated to it. In Select mode, single. Right click on a connection or part of a connection drops down the context sensitive menu which has a.
Type in the required net name Or select an existing one from the Pick List and either accept the. Note that allocating net names and net classes is not mandatory, but if the schematic is subsequently to be.
Try dropping a Resistor on to a connection. See how the net is automatically split and that you are. Busses can be created, combined and split with impressive simplicity. Both Open and Closed busses are. Busses have not been specifically detailed here but are available for you to try in the demo version.
The [Position Plot] button opens up a menu giving you full control over the printing process including. We will finish the Schematic section here in 'mid-air' but the design process is continued now into PC B.
The PC B Technology file has set up the layers used, the display colour allocated to those layers, the. All with one key stroke! This produces dramatic improvements in productivity for professional users and. Named Styles allow the user to set up sensibly recognisable Net Classes, track widths, pad types etc. For Example track styles can be given names like Clock, Signal, 50 Ohm, Ohm, Low power, High voltage, etc.
Technology files and the Net Classes included in them allow sets of these pre-defined parameters to. Technology files can be created as new files, but can also be extracted from existing designs. These can. Continuing from the end of the Schematic section, where we left the Translate to PC B dialog waiting for. You may have already previously pressed the [OK] button, in. Components of similar types are stacked up in piles and all are. The components can be picked up and moved by clicking and dragging on any of their Pins or Pads in.
Zoom out a little and adjust the scroll bars until there is a clear area above the group of components, a.
