Does for loop is synthesizable in Verilog?

It is not synthesizable. The number of times that the for loops is not known at compile time.

CAN YOU DO for loop in Verilog?

Verilog For Loop. When writing verilog code, we use the for loop to execute a block of code a fixed number of times. As with the while loop, the for loop will execute for as long as a given condition is true. The specified condition is evaluated before each iteration of the loop.

What does a for loop do in synthesizable code?

For loops in synthesizable code are used for expanding replicated logic. They are simply a way of shrinking the amount of code that is written by the hardware designer. They do not loop like a C program loops. They only expand replicated logic.

Is for loop a synthesizable construct?

A for loop is synthesizable as long as the compiler can determine the number of loop iterations statically. Then it will unroll the loop. A foreach loop is even easier to synthesize because as long as the array is a fixed size, the loop iteration count is fixed as well.

What is synthesizable 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.

Is $clog2 synthesizable?

$clog2 is not supported by Verilog. It is a SystemVerilog system task. Moreover, system tasks are not synthesizable.

Is always block synthesizable in Verilog?

Embedded always blocks are not synthesizable. Show activity on this post. Adding timing delays would not be synthesisable, but often used in verification. Also some tools will complain if you try to synthesise display statements.

Are integers synthesizable in Verilog?

The integer type is synthesizable, but real is not synthesizable. real is synthesizable in SystemVerilog .

Why are while loops not synthesizable?

The reason that while loops do not belong in synthesizable code is that when the synthesis tool tries to turn your code into gates and registers it needs to know exactly how many times the loop will run. It will only expand replicated logic a determinate number of times.

Is SystemVerilog synthesizable?

There is a common misconception that “Verilog” is a hardware modeling language that is synthesizable, and “SystemVerilog” is a verification language that is not synthesizable. That is completely false!

Are SystemVerilog tasks synthesizable?

Yes, tasks can be synthesized! Below is a list of rules for tasks: Tasks can have any number of inputs and outputs.

Are SystemVerilog functions synthesizable?

Yes, functions are synthesizable!
