Symbol Generator Demonstration
Symbol Generation is often the first step in producing a schematic, use the
following steps to build a part from its description in the library. Notice
that there is an action, build, that is being performed with reference to the
library. This is an idication that a part in the library is not kept as a
collection of symbols, but instead a set of instructions on how to construct
the symbol in a given appearance, brought into play when necessary. More on
this later, here's what to do to get started,
To select a part, first use
(select)
to choose a part to build
To select a template, then use
(extract)
to extract pin names
To build a symbol, finally use
(build)
to construct the part
The example sequence above builds the selected part from information contained
in a library. Parts are often available with more than just one appearance.
For instance, a plan view is usually available
as a default. In addition, a various pretty
views offering different arrangment of pins may be available.
The variety in part appearances is not limited to only pin placement in the
generated part symbol, the pin names themselves are considered to be an
alterable element of appearance.
Each variation of a given part's appearance is made available to the user to
choose in an effort to suit individual preference. If the desired appearance
does not already exist in the library, a user may interact to produce an
appearance more to their liking. This is done by modifying the template for
a given appearance to produce a rendition that does work for the user.
Of course, the default appearance, usually plan view, my be used if time
is of the essence, and no other better representation is availabe.
