Using the Tools menu, start the gate level simulation:. Gate level simulation

It is used widely -- from high-level descriptions down to gate-level ones -- to validate several aspects of the design, particularly functional correctness. 3. · Gate level Simulation (GLS) is done at the late level of Design cycle. Select gates from the dropdown list and click add node to add more gates. · Gate level simulation represents a small slice of what should actually be tested for a tape-out. In all cases, getting a gate-level simulation up and running is generally accompanied by a series of challenges so frustrating.  · Gate Level modeling. A list of all synchroniser flops is generated using CDC tools. . · Compared to gate-level modeling, dataflow modeling in Verilog is a higher level of abstraction.

The simulation of this netlist is called gate level simulation. An alternative way to solve this is to formally prove that the RTL code and the netlist synthesized from it have exactly the same behavior in all (relevant) cases. That’s really helpful because gate-level modeling becomes very complicated for a complex circuit. The simulation semantics of conditional constructs in both HDL languages, Verilog and VHDL, are insufficient to accurately model the ambiguity inherent in un-initialized registers and power on reset values.
