The PLD (programmable-logic-device) code in Listing 1 implements a pc-board-level revision-detection system that detects whether PLD pins are shorted together on a pc board. It is often advantageous ...

The PLD (programmable-logic-device) code in Listing 1 creates arbitrary-resolution, pulse-width-modulated (PWM) generators. PWM generators are useful as low-bandwidth D/A converters in hardware of ...

This idea presents PLD code that can be used to generate arbitrary polynomial cyclic-redundancy-check (CRC) functions. Communication systems often use CRCs to detect transmission errors.
