Learn SYSTEMVERILOG with Real Code Examples

SystemVerilog combines design and verification constructs into a single language.

Supports hardware modeling at RTL (Register Transfer Level) and behavioral levels.

Includes object-oriented programming features for verification environments.

Provides assertions, coverage, and constrained randomization for functional verification.

Widely used in ASIC, FPGA, and SoC design and verification workflows.

RTL design constructs inherited from Verilog

Advanced verification constructs (classes, randomization, assertions)

Interfaces for modular connectivity

Packages for reusable code

Clocking blocks for synchronized stimulus

Module: basic hardware building block

Interface: encapsulates signals and connectivity

Class: object-oriented construct for verification

Assertion: checks properties during simulation

Constraint: defines rules for random stimulus generation

Design RTL source files (.sv)

Verification files (classes, sequences, testcases)

Interface definitions (.sv)

Coverage and assertion definitions

Simulation scripts and makefiles

Write RTL modules for design functionality

Develop verification classes and testbenches

Connect DUT to testbench via interfaces

Simulate design and monitor outputs

Analyze coverage and assertion results to ensure correctness

Beginner: small combinational or sequential circuit

Intermediate: simple FSM with assertions

Advanced: SoC verification with constrained random testbench

Expert: coverage-driven verification and formal property checking

Architect: full-chip verification with reusable environment

SystemVerilog vs Verilog: adds verification, OOP, assertions, and coverage

SystemVerilog vs VHDL: more verification-friendly, syntax differences

UVM vs plain SystemVerilog: methodology framework vs language features

RTL simulation vs emulation: software vs hardware-accelerated

Formal vs simulation: exhaustive vs randomized checking
