Behavioral modeling is the highest level of abstraction in the Verilog HDL. The other modeling techniques are relatively detailed. They require some knowledge of how
Data flow modeling
Dataflow modeling is a higher level of abstraction. The designer no need have any knowledge of logic circuit. He should be aware of data flow
Gate level Modelling
The module is implemented in terms of logic gates and interconnections between these gates. Designer should know the gate-level diagram of the design Gate primitives
Gate delays
Gate Delays In Verilog, a designer can specify the gate delays in verilog code. This helps the designer to get a real time behavior of
Basics : Data Types III
Vectors Vectors can be a net or reg data types. They are declared as [high:low] or [low:high], but the left number is always the MSB
Basics : Data types II
Integers Integer is a register data type of 32 bits. The only difference of declaring it as integer is that, it becomes a signed value.
Basics : Data Types I
Value Set The Verilog HDL value set consists of four basic values: 0 – represents a logic zero, or a false condition. 1 – represents
Synchronous Reset and Asynchronous Reset
A Reset is required to initialize a hardware design for system operation and to force an value into a known state for simulation. A reset
CHISEL : Vec
A Vec in chisel represents a collections signal (same type). These are similar to the array data structures in other languages. Each element in Vec
CHISEL : Bundle
In Chisel provides two constructs to group related signals A Bundle to group signals of different type. A Vec represents the collection of signal of
