Learn how to write automatic tasks for your Verilog testbench simulations. Example code shown. ,images/main/bulllet_4dots_orange.gif, Example - CPU Write / Read Task. Below is the waveform used for writing into memory and reading from memory. We make the assumption that there is a need to use this interface from multiple agents. So we write the read,Syntax, Function Declaration function [msb:lsb] function_name; input [msb:lsb] input_arguments; reg [msb:lsb] reg_variable_list; parameter [msb:lsb] parameter_list; integer [msb:lsb] integer_list; ... statements ... endfunction. Verilog Function Declarati,Examples. Example 1. function [15:0] negation; input [15:0] a; negation = ~a; endfunction. A function returning 16-bit value. Example 2. function real multiply; input a, b; real a, b; multiply = ((1.2 * a) * (b * 0.17)) * 5.1; endfunction.
