A single bit multiplexer will have one control line two inputs ( say X and Y) and one output ( say Z). When the control is 0, X is connected to Z. When the Control is 1, Y is connected to Z. The figure below explains this. Let write this example using verilog case statement. // www.referencedesigner.com Verilog Code for 3:8 Decoder using Case statement. Decoders are combinational circuits used for breaking down any combination of inputs to a set of output bits that are all set to '0' apart from one output bit. Therefore when one input changes, two output bits will change. Lets say we have N input bits to a decoder, the number of output bits will.

The hexadecimal to 7 segment encoder has 4 bit input and 7 output. Depending upon the input number, some of the 7 segments are displayed. The seven segments are represented as a,b,c,d,e,f,g. A high on one of these segements make it display. For example to write 1 we need to display segments b and C. The 7 segment display also has a decimal. Continuous assignment statement can be used to represent combinational gates in Verilog. Example #2. The module shown below takes two inputs and uses an assign statement to drive the output z using part-select and multiple bit concatenations. Treat each case as the only code in the module, else many assign statements on the same signal will definitely make the output become X Below is the truth table for a decimal to BCD encoder. From the truth table, the outputs can be expressed by following Boolean Function. Note: Below boolean functions are formed by ORing all the input lines for which output is 1. For instance Y0 is 1 for D1 , D3 , D5 , D7 & D9 input lines. Y0 = D1 + D3 + D5 + D7 + D9. Y1 = D2 + D3 + D6 + D7 Here is an implementation in Verilog. The output of the comparator is zero if both 2-bit inputs are equal, otherwise, the right bit is one if the first input is greater than the second input, and the left bit is one if the second input is greater. YCbCr 4:2:0 = 137 cycles per 8x8 pixels (2.1 cycles per pixel) YCbCr 4:4:4 = 198 cycles per 8x8 pixels (3.1 cycles per pixel) Use Case. The purpose of this design was to replace a 3rd party JPEG decoder core used in my Motion JPEG based FPGA video player
The Verilog case statement is a convenient structure to code various logic like decoders, encoders, onehot state machines. Verilog defines three versions of the case statement: case, casez, casex.Not only is it easy to confuse them, but there are subtleties between them that can trip up even experienced coders Please help me with these 2 questions.. 1) Do this code without using if-eles statments!!! 2) Do this code using anything possible.
