EDA Playground

Overview

EDA Playground is a free, browser-based integrated development environment (IDE) focused on hardware description and verification languages. It allows users to write, compile, and simulate SystemVerilog, Verilog, and VHDL code directly from a web browser, and to share runnable examples with others through public "playground" URLs.

The EDA Playground project repository describes itself as "The FREE IDE for SystemVerilog, Verilog, and VHDL". The repository is published under the GitHub organization edaplayground (repository edaplayground/eda-playground), with primary language HTML and a public update timestamp of 2026-08-07.

Typical Usage in Hardware Verification Projects

EDA Playground is frequently used in the hardware-verification community as a lightweight, zero-install platform for demonstrating SystemVerilog testbenches and UVM-based verification environments. Projects typically embed an EDA Playground link inside their README so reviewers can launch the exact sources and testbench in a browser.

For example, the gupta409/Processor-UVM-Verification repository — a SystemVerilog UVM-based verification of a 5-stage pipelined MIPS processor — exposes its design on EDA Playground via the link https://www.edaplayground.com/x/aevr, attributed to contributor @rpjayaraman.

Educational SystemVerilog content also leverages EDA Playground. A blog post on Rincón de SystemVerilog (DSD, UPV) describing constrained-random stimulus generation and functional coverage for microprocessors embeds the project's sources inside an iframe pointing to https://www.edaplayground.com/x/jztC, allowing readers to execute the example live. The same post illustrates typical EDA Playground workflows such as:

• Defining a SystemVerilog package (utilidades_verificacion) containing typed mailboxes and classes for random-coverage stimulus generation (RCSG_RISCV, covergroups_RISCV).
• Declaring an interface if_rom with modports (monitorizar, testar, duv) to interconnect the design under verification with the testbench.
• Using #0 (zero-delay) sampling to manually synchronize monitor reads with driver updates.
• Compiling with vendor simulator flags, e.g. vlog +define+debug_aleatorio rom_aleatoria.sv, to switch between a synthesizable ROM loaded from a file and a randomized ROM model.

These examples highlight EDA Playground's role as a sharable runtime for short, self-contained SystemVerilog and UVM demonstrations.
