Advanced Boolean Expression Language
The Advanced Boolean Expression Language (ABEL) is an obsolete hardware description language (HDL) and an associated set of design tools for programming programmable logic devices (PLDs). It was created in 1983 by Data I/O Corporation, in Redmond, Washington. ABEL includes both concurrent equation and truth table logic formats as well as a sequential state machine description format. A preprocessor with syntax loosely based on Digital Equipment Corporation's MACRO-11 assembly language is also included. In addition to being used for describing digital logic, ABEL may also be used to describe test vectors (patterns of inputs and expected outputs) that may be dow
