Schema to new Symbol

(File Menu)

This command is very important to create user-defined symbols in order to build hierarchuical designs. As an example, the full adder diagram based on primitives can be translated into a single symbol which includes the structure, input and outpus, as shown below.

I/Os. The list of I/Os is based on active symbols (buttons, clocks, leds, keyboards, etc…). The position and side in the symbol may be changed in the table.

VERILOG. The structural description based on primitives is described in verilog format and included to the symbol description.

REFRESH. Update the layout of the user symbol.

SIZING. Act on the icons to change the shape of the user symbol.
SYMBOL PROPERTIES. This properties may be changed by the user.
