The biggest controversy between Verilog and VHDL has been a matter of philosophy. You can also learn more about test bench creation at 6/16/09 Creating those test benches is the subject of my book FPGA Simulation: A Complete Step-by-Step Guide.

Also, members of the FPGA Simulation newsletter will receive new versions of this primer as I update it based on feedback.ġ. The website hosts forums where you can ask those questions and learn more about SystemVerilog. You’ll probably have more questions about SystemVerilog after reading this primer than you had before reading it.

(The Language Reference Manual for SystemVerilog is over 1400 pages long.) Instead, it describes the basic features of SystemVerilog and provides enough SystemVerilog information so that a VHDL engineer could create test benches like those in FPGA Simulation: A Complete Step-by-Step Guide. This primer is not a complete description of SystemVerilog. Likewise, it's much easier for a VHDL engineer to learn SystemVerilog if the latter is described in terms of VHDL. It's easier to say that “a softball is like a baseball, only bigger,” than to describe the specifications of a softball from scratch. People learn faster when they can anchor new concepts to existing concepts. This primer teaches VHDL users about SystemVerilog in the terms of VHDL.

#FPGA SIMULATION RAY SALEMI HOW TO#

Engineers learning how to do modern verification are learning how to write in SystemVerilog. SystemVerilog is an open language that is replacing the proprietary language e, which was the granddaddy of all verification languages. The Open Verification Methodology (OVM) is one such library.

Object-oriented programming allows engineers to encapsulate complex behaviors in easy-to-use objects and reuse them. It delivers features such as randomization, functional coverage, and assertions, which allow engineers to create powerful test benches.1 SystemVerilog allows users to create objects and implement object-oriented libraries. SystemVerilog is an extension of Verilog. When it comes to writing test benches and simulating complex designs, the clear winner is SystemVerilog. The same cannot be said in the world of verification. But because both languages still exist for RTL design, one has to conclude that either can be used to design logic successfully. I say this because if there were a clear winner, the market would have shaken it out by now. The answer to this question has become clear: both languages work for RTL design. The debate between Verilog and VHDL has raged for twenty years, and as an AE for Mentor Graphics I still get questions about which is the better language.
