SystemVerilog

SystemVerilog is an HDL that is a superset of Verilog with additional features. This includes object-oriented features, the ability to specify testbenches, and more flexible and expressive syntax. It is to Verilog what C++ is to C.

Language features

• Hierarchical design
• always block (always_comb, always_ff)
• case statement
• Non-blocking assignment
• Universal Verification Methodology

Development environment

An opinionated set-up:

• Text editor — Visual Studio Code with extension Verilog/SystemVerilog Tools
• Testbenches and simulator — cocotb with Questa (possibly iverilog too)
• Formatter and language server — Verible
• Linter — Slang

Quick install

choco install vscode
choco install iverilog
