The UVM class library brings a framework and automation to the SystemVerilog language such as sequences and data automation features (packing, copy, compare) etc., and unlike the previous methodologies developed independently by EDA (Electronic Design Automation) Vendors, is an Accellera standard with support from multiple vendors: Aldec ...
The OVM also brings in concepts from the Advanced Verification Methodology (AVM). The UVM class library brings much automation to the SystemVerilog language such as sequences and data automation features (packing, copy, compare, etc.). The UVM also has recommendations for code packaging and naming conventions.
eRM formed the basis of the URM (Universal Reuse Methodology) developed by Cadence Design Systems for the SystemVerilog verification language. URM, together with contribution from Mentor Graphics' AVM, later became the OVM (Open Verification Methodology) , and eventually becoming the UVM (Universal Verification Methodology) .
Whereas Verilog used a single, general-purpose always block to model different types of hardware structures, each of SystemVerilog's new blocks is intended to model a specific type of hardware, by imposing semantic restrictions to ensure that hardware described by the blocks matches the intended usage of the model. An HDL compiler or ...

The original Verilog simulator, Gateway Design's Verilog-XL was the first (and only, for a time) Verilog simulator to be qualified for ASIC (validation) sign-off. After its acquisition by Cadence Design Systems, Verilog-XL changed very little over the years, retaining an interpreted language engine, and freezing language-support at Verilog-1995.
