VHDL Code
VHDL Code For 8:1 multiplexer Multiplexer is simply a data selector.It has multiple inputs and one output.Any one of the input line is transferred to output depending on the control signal. An 8-to-1 multiplexer is a digital device that selects one of the eight inputs lines to the output line by using three-bit selection line. The block diagram of 8-to-1 Mux is shown in Figure 1. A 2 n-to-1 multiplexer needs n bit selection line to select one of the 2 n inputs to the output. Mux is a device That has 2^n Input Lines. But Only One has Output Line. Where n= number of input selector line. Mux is A device Which is used to Convert Multiple Input line into one Output Line. At a time only one Input Line will Connect to the output line. Which Input Line Connected In Output Line is decided by Input Selector Line. ENTITY multiplexertest IS END multiplexertest; ARCHITECTURE behavior OF multiplexertest IS And also you need to change the top entity to multiplexertest instead of testbench. Or if you just rename the testbench module from multiplexer to testbench then you don't need to do the second step. vhdl code Write an 8:1 multiplexer module called mux8 with inputs S 2:0, d0,d1,d2,d3,d4,d5,d6,d7, and output y by using parameterized module. 8:1 mux vhdl Search and download 8:1 mux vhdl open source project / source codes from CodeForge.com CodeForge. This is a typical black wave generator program and an arbitrary waveform generator. A 'select' input to the multiplexer allows the source of the signal to be chosen.
