Verilogger Extreme is a newer, compiled-code simulator that is Verilog-2001 compliant and much faster than Pro. Verilog-XL: Cadence Design Systems: V1995: 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.

Verilog-2001 is a significant upgrade from Verilog-95. First, it adds explicit support for (2's complement) signed nets and variables. Previously, code authors had to perform signed operations using awkward bit-level manipulations (for example, the carry-out bit of a simple 8-bit addition required an explicit description of the Boolean algebra ...
Verilog/AMS is a superset of the Verilog digital HDL, so all statements in digital domain work as in Verilog (see there for examples). All analog parts work as in Verilog-A. The following code example in Verilog-AMS shows a DAC which is an example for analog processing which is triggered by a digital signal:
Icarus Verilog is an implementation of the Verilog hardware description language compiler that generates netlists in the desired format and a simulator. It supports the 1995, 2001 and 2005 versions of the standard, portions of SystemVerilog , and some extensions.
Initially, Verilog and VHDL were used to document and simulate circuit designs already captured and described in another form (such as schematic files). HDL simulation enabled engineers to work at a higher level of abstraction than simulation at the schematic level, and thus increased design capacity from hundreds of transistors to thousands.
Verilator converts synthesizable Verilog to C++, while C++ library could be compiled into a MEX file using MATLAB interface to C++. This is how Verilog designs can be directly simulated from MATLAB. Using compiled C++ models with MATLAB is faster than using co-simulation interfaces with a separate hardware description language (HDL) simulator ...
Unified linker / elaborator for Verilog, VHDL, and SystemC libraries. Generates a simulation object file referred to as a snapshot image. NC Sim ncsim Unified simulation engine for Verilog, VHDL, and SystemC. Loads snapshot images generated by NC Elaborator. This tool can be run in GUI mode or batch command-line mode.
