BCD2SevenSegment

Library:	BFH mega functions
Introduced:	3.x.x

Behavior

This component converts a four-bit binary-coded-decimal digit to a format suitable for use with a 7-Segment Display. The BCD2SevenSegment component as a "hole" in the center, sized to exactly fit one such display.

This component is not necessary in most scenarios—it was created as a stop-gap measure before FPGA support was added to many components, but is no longer useful for new circuits. Rather than using a BCD2SevenSegment converter paired with a Seven Segment Display, you can simply use a Hex Digit Display alone (which internally contains suitable number format conversion logic).

Pins

South edge (input, four bits)

The binary-coded-decimal digit to be converted.

Inside edges (seven outputs, one bit each)

Outputs corresponding to the seven inputs of a 7-Segment Display.

Properties

None.

Note: A number of properties are defined for this component, but none are useful in any way. They should all be ignored.

Poke Tool Behavior

None.

FPGA Synthesis

Supports VHDL synthesis.
