SystemVerilog vs Verilog in RTL Design
academic.csuohio.eduVerilog is intended mainly for the gate‐ and register‐transfer‐level design and modeling. It became the IEEE Standard 1364‐1995 in 1995 (referred to as Verilog‐95), revised in 2001 (referred to as Verilog‐ 2001) and again in 2005 (referred to as Verilog‐2005).
Introduction to Verilog HDL
athena.ecs.csus.eduVerilog •Verilog was developed by Gateway Design Automation as a proprietary language for logic simulation in 1984. •Gateway was acquired by Cadence in 1989 •Verilog was made an open standard in 1990 under the control of Open Verilog International. •The language became an IEEE standard in 1995 (IEEE STD 1364) and was updated in 2001 and
