Hello,I am working with behavioral Verilog design.
Can you help me to getan idea about how control flow is flattened out in behavioral Verilog and peopleusually claim that control flow in Verilog is obscure and control flowis encoded in Verilog in data-encoded way.Can you please give me a small example (say a FSM, or a counter) and helpme to understand that how is control flow in Verilog is encoded indata-driven way?I would appreciate any help in this regard.Many thanks in advance.Thank You. Hello Evgeni,Many thanks for your reply.I would like to clarify here that what I meant by “data-encoded way”. I am workingwith behavioral synthesizable subset of Verilog that allows control-flow statements like if-else and switch(case) but does not allow repeat, for, while, continue statements. So, in a sense, the behavioral code structure in Verilog has a flattened control-flow structure in it (without these loop constructs). This is easy to see because you can model the effect of while or for loops using only if-then-else and switch(case), but in a data-encoded way.So, the FSM examples you referred has the same modeling with flattened control-flow.

Can you please give me some more insight or references on this.From your experience, did you come across any behavioral Verilog designs that has an explicit control-flow structure which is not flattened. Also, please informwhether any behavioral synthesis tool allow loop constructs like for, while, repeat, an forever?Many Thanks in advance.Looking forward.Regards,Rajdeep. Hello Evgeni,Many thanks for your reply.I agree that loop-unrolling is a popular term used in this context.Further along the same lines, I am inquisitive to know the following from you.As “for” loops are synthesizable by behavioral synthesis tool, sogiven a behavioral Verilog design with for loop inside it, how does abehavioral synthesis tool deal with it?
Does it always unroll the loop ordoes it perform partial unrolling? Depends on what factors.Can you please share something on this.Many thanks in advance.Regards,Rajdeep. Hi Rajdeep,I think exact behavior and limitations are not part of the specification, and depend on the synthesis tool. You need to consult the manual and even talk to tech support of that tool.But generally speaking, if the loop is unfeasible, for example if it contains so many loops that cannot be unrolled to fit the chip, then it’s going to fail – either during synthesis or place and route.Another place to get more information are HLS (high level synthesis) tools such as Xilinx Vivado ESL. HLS tools heavily use loop constructs.Thanks,Evgeni.

Hi Evgeni,Hope you are fine.I have a query regarding development of control-path intensive behavioral verilog design.
Currently, I have developed a IEEE 754 32-bit floating-point Add/Sub unit in verilog which is quite data-path intensive. But I am looking for a control-path intensive design in Verilog like USB controller, memory controller etc.
I got few designs from Opencores but I cannot characterize whether these designs have enough control-path in it just by looking at the code. Can you please tell what are the major characteristics of any control-path intensive designs in Verilog. If I spotsome data-path units, and a FSM in a design, can I consider it as design withcontrol-path.Looking forward to your reply.Many ThanksBest regards,Rajdeep. Hello Evgeni,Thank you for your reply.If a design has separate data-path and control-path then the basiccharacteristics if such design is that the controller is a FSM which controlsthe operations in the data-path. But not all control-path and data-pathmixed model of designs reflects this characteristics due to design complexity.But isn’t it the case that a control-path intensive design will always have a FSMcontroller to control circuit operations and the complexity of the design dependson the number of states in the FSM controller. Isn’t this a metric to characterisecontrol-path intensive designs.Please correct me if I am wrong.Best regards,Rajdeep.
