Verilog HDL Model Based Thermometer-to-Binary Encoder with Bubble Error Correction

Z. Jaworski (Warsaw Univ. of Techn., Poland)

This paper compares several approaches to come up with the Verilog HDL model of the thermometer-to-binary encoder with bubble error correction. It has been demonstrated that implementations of different ideas to correct bubble errors yield circuits whose parameters tremendously vary in delay, area and power consumption. The shortest delay is achieved for the design synthesized from the model which mimics a human reading temperature on classic liquid-in-glass thermometer.
