What are synthesizable constructs in Verilog?

What are synthesizable constructs in Verilog?

Synthesizable Verilog is that subset of the language that are accepted by the synthesis tools. The non-synthesizable constructs are used only for simulation and the synthesis tool cannot handle them.

Which is a synthesizable construct?

Synthesizable and Non-Synthesizable Verilog constructs

What is synthesizable and non synthesizable in VHDL?

Synthesizable statements- The statement which directly can be used to generate the Hardware called Synthesizable statements. Ex- A 3-input AND gate, A 32-bit output bus. Non-Synthesizable statements- The statements which can’t make any hardware is known as Non-synthesizable. For generating delay we have a counter.

What is synthesizable and non synthesizable VHDL statements?

Are Verilog functions synthesizable?

Yes, functions are synthesizable! Below is a list of rules for functions: Functions can have any number of inputs but only one output (one return value)

Are cases synthesizable?

Both casex and casez are synthesizable. Casex generates a don’t-care space for unspecified state points. Casez uses a “Z logic value” to represent a don’t-care bits.

Are tasks synthesizable?

yes both task & functions are synthesizable. Provided that the task does not have the timing constructs. you can use tasks inside a clocked always block and your code is synthesizable. You can (and should) use tasks to replicate repetitive code without adding a lot of code lines.

Is case statement synthesizable in Verilog?

They are more efficient than using if/else statements because if/else can generate long carry-chains of logic that can cause difficulties meeting timing. // *Initial* is never synthesizable. Test code only!
