Vhdl Models of Digital Combinatorial Circuits on the Current - Mode Gates

This paper deals with problems of logical level designing, modelling and simulations of digital, combinatorial circuits, which are based on the current mode gates – new digital elements operating with constant, continuous power supply current. For the modelling and simulation purpose some elements of standard Active – VHDL library IEEE1164 were changed. All designed circuits (one and four bits adders, decoder, 32 – functions arithmetic – logic unit (ALU)) were described as VHDL models. Active – VHDL simulations verified both the method of designing and changes introduced into the standard VHDL library IEEE1164.
