Synthesizable vs. Non-Synthesizable Constructs Synthesizable constructs are those that can be automatically generated by a hardware description language...
Synthesizable constructs are those that can be automatically generated by a hardware description language (HDL) like Verilog, VHDL, or SystemVerilog. This means that the HDL can create the circuit from the HDL description.
Non-synthesizable constructs require human intervention and manual implementation. This means that the designer needs to explicitly define the circuit in the HDL.
Examples of synthesizable constructs:
Combinational logic gates (AND, OR, XOR)
Flip-flops
Decoders
Comparators
Examples of non-synthesizable constructs:
Buses
Buffers
Memory cells
Analog-to-digital converters (ADCs)
Digital-to-analog converters (DACs)
The main difference between synthesizable and non-synthesizable constructs lies in the level of automation involved in their creation. Synthesizable constructs are highly automated and can be generated directly from the HDL description. On the other hand, non-synthesizable constructs require human intervention and manual coding.
Benefits of using synthesizable constructs:
Automates the design process, reducing manual effort and potential errors.
Reduces development time and cost.
Allows for more complex designs with multiple components and interconnections.
Benefits of using non-synthesizable constructs:
Provide more flexibility and control over the design.
Can handle designs with complex interconnections or multiple levels of hierarchy.
Offer better performance in some cases.
In summary:
Synthesizable constructs:
Automatically generated from HDL descriptions.
Highly automated design process.
Suitable for simple designs with few components and connections.
Non-synthesizable constructs:
Manually implemented by the designer.
Require human intervention for each component.
Suitable for complex designs with many components and intricate connections
