Veritak is a Verilog HDL Compiler/Simulator that supports the major Verilog 2001 HDL features. It provides an integrated environment, which includes a VHDL to Verilog translator, a syntax highlighting editor (called Veripad), a class hierarchy viewer, a multiple-waveform viewer capable of handling a gigabyte vcd files, source analyzer, and more -- it is available for Windows XP/2000/2003/Vista32/Vista64/Windows7 32bit/64bit..

If you are looking for a fast Verilog HDL simulator with a full-function GUI for professional use, while maintaining an extremely low price, this is it. You can try Veritak at no cost for two weeks.

See our Benchmark Results for Veritak performance details. ( Benchmarking performed with an Athlon 3800+ Dual including Verilator's Verilog Simulator Benchmarks. )

Enabled selective save for waveform view. This release also includes Library Compilation speed improvement. 
Our new tool bar Icons below and Veritak product Graphic shown above have been developed by "Tim Ruetz (caiaq.de)".





Snapshot from Version 3.10A

  The Veritak waveform viewer is now 64-bit enabled. This means you can now view long simulations, well over 2GB, as a waveform. You can view large vcd files (several hundreds mega bytes in size) as well.

 The largest IP core in opencores can be in viewed in full using the Veritak giga byte viewer.
(7.5GB for the entire archive (if VCD file used, it may be over 200GB.), and 3GB for the display)
