Initially the reg value of undefined and hence we have placed 4'bxxxx in its value. Here is the verilog implemmentation of shift register. The picture shows the scheme of the shift register. At each clock cyccle the right most bit of the register comes out. The whole design also has and output that we are c calling s_out. At each clock cycle, the content of the register shifts to the right and s_in enters into the leftmost bit or the MSB bit. Our shift register has an s_in input entering on its left hand side. Verilog Code for Parallel in Parallel Out Shift Register - Free download as Word Doc (.doc /.docx), PDF File (.pdf), Text File (.txt) or read online for free. The below presented verilog code for 4-bit universal shift register acts as a uni-directional shift register for serial-in and serial-out mode. Module shiftreg32b (clk, reset, shift, carrega, in, regout) input clk input reset, shift input to an output in a combinational module in Verilog Verilog Illegal Reference to net 'OUT' What does this Verilog module do? It contains many explicit features which include parallel inputs, parallel outputs, synchronous reset, bidirectional serial input and bidirectional serial output. I wrote a parallel in serial out shift register, which I present here. Serial Input Serial Output Shift Register.
