A friend asked for help with an old Cyclone I board that lacks reset buttons, switches, or any other reset mechanisms. The board has only four common cathode seven-segment displays and 16 LED lights. The task was to write a Verilog code to test the board. The requirements are as follows: (1) The inp...
74HC595 Overview The 74HC595 is an 8-bit serial-in, parallel-out shift register featuring storage capabilities and tri-state outputs. This integrated circuit efficiently converts serial data into parallel output, making it ideal for applications requiring expanded output capacity while conserving FP...
Introduction to Verilog HDL Basic Concepts Fundamental Modules // Constant output module module constant_output ( output logic one ); assign one = 1'b1; endmodule // Zero output module module zero_output ( output logic zero ); assign zero = 1'b0; endmodule Wire Connections // Signal passthrough modu...
A Synchronous FIFO (First-In, First-Out) is a digital storage structure where data is written and read using a single clock source. This component is essential for buffering data streams between logic blocks that operate within the same clock domain but may process data at different rates. Core Desi...
Overview This example implements a minimal AHB‑Lite–style interconnect that supports single, non‑burst transfers with no wait states. The system contains one master and four simple memory‑mapped slaves. Because there is only one master, no arbiter is required. An address decoder generates one‑hot se...
