SystemVerilog & Verilog RTL Design Projects Overview This repository serves as a portfolio of Digital Logic Design projects ranging from basic combinational circuits to advanced sequential systems and communication protocols. The cycle-accurate simulation model provides the speed needed for comprehensive testing, while C++ integration brings powerful features like file I/O, sophisticated data structures, and standard debugging tools. Check more such examples in the Verilog Tutorial ! Learn how to design and test 4-bit up, down, up-down, and random counter in Verilog with detailed code examples and testbenches. In Solution 3, the testbench instantiates both mult64x64_check_s and mult64x64_check_us and selects the expected output based on the current value of tc. This allows a single test run to cover both signed and unsigned paths. Verilator's C++ testbench capability transforms verification from a Verilog-only exercise into a full software engineering discipline. Learn Verilog, SystemVerilog, UVM with code examples, quizzes, interview questions and more ! 1 day ago · Popular repositories verilog-3bit-counter Public 3-bit synchronous counter in Verilog with testbench and simulation results Verilog Simulation results, verilog code and testbench are included in the PDF. You then write a C++ testbench that instantiates and drives this compiled design. Verilog code for the counters is presented. Suitable for college-level education. This repository contains the Verilog code for a simple counter module along with an associated testbench for functional verification. The testbench VHDL code for the counters is also presented together with the simulation waveform. . In this VHDL project, the counters are implemented in VHDL. These counters form Verilator takes a fundamentally different approach to simulation. Demonstrates digital logic design principles. It covers the testbench validation methodology, observed waveforms, and latency measurements for both simulation phases. In this project, Verilog code for counters with testbench will be presented including up counter, down counter, up-down counter, and random counter. Each folder represents a standalone project designed with synthesizable RTL code, accompanied by testbenches for Icarus Verilog is an open-source Verilog simulation and synthesis tool that has been under active development since the late 1990s. Whether you're a student, an enthusiast, or a professional, understanding how to implement counters using Verilog is crucial. The counter increments on every positive edge of the clock and resets asynchronously when reset is asserted. Verilog code for a synchronous counter module and its testbench. 3 days ago · Each reference module computes the expected product using Verilog's built-in * operator, serving as a golden model. Learn how to code 4-bit up counter in verilog, and simulate using a simple testbench. Jul 23, 2025 · Conclusion In this article, the design and implementation of a 4-bit up-down synchronous counter using Verilog HDL was covered. The counter module is designed to count up or down based on the control signals and can load data on demand. 1. vishal-baliyan-vlsi / verilog-3bit-counter Public Notifications You must be signed in to change notification settings Fork 0 Star 0 This project implements a 3-bit synchronous up counter using Verilog HDL. The design is instantiated in a test bench, stimulus is applied to the inputs, and the outputs are monitored for the desired results. For timing and resource analysis Last time, several 4-bit counters including up counter, down counter and up-down counter are implemented in Verilog. The result? Simulation speeds 10-100x faster than event-driven simulators, with the full power of C++ at your Hands-on with Verilog AND gate: Wrote the RTL module and a testbench, simulated using Icarus Verilog, and visualized the waveform in GTKWave. 3 days ago · Simulation Results Relevant source files This page documents the functional RTL (pre-simulation) and gate-level (post-simulation) results for Solution 1's 64×64 unsigned multiplier. Unlike commercial simulators that can cost thousands of dollars, Icarus Verilog provides robust simulation capabilities completely free. For the architecture that produces these results, see 2. Instead of interpreting your Verilog code line-by-line like traditional simulators, it compiles your design into optimized C++ code. It also gave information about the counters, description of the Verilog code and pros and cons of adopting Verilog HDL for counters. pez isq fkp vpz ulm pnf rzq xts psy pup yoq gsl aik lgi vrt
