Hi Rajdeep, I think exact behavior and limitations are not part of the specification, and depend on the synthesis tool.
New Book: 100 Power Tips for FPGA Designers
Extensive preview is available. E-Mail will not be published required.
Many thanks in anticipation. April 30th, at April 28th, at Many Thanks in advance. Thank you for your reply. Paperback edition on Amazon. Download source code, projects, and scripts.
Code examples are written in Verilog HDL. Also, please inform whether any behavioral synthesis tool allow loop constructs like for, while, repeat, an forever? At least the ones I worked with: I am working with behavioral synthesizable subset of Verilog that allows control-flow rips like if-else and switch case but does not allow repeat, for, while, continue statements. December 20th, at Can you please give me some more poser or references on this. Depends on what factors.
December 18th, at Such a control-path intensive design might also have a lot of control logic with FSMs inside the datapath. I used a second clock buffer in an attempt to bring the MHz multiplied clock out to an external pin. Looking forward to your reply.
If a design has separate data-path and control-path then the basic characteristics if such design is that the controller is a FSM which controls the operations in the data-path. Hello, I am working with behavioral Verilog design. Hello Evgeni, what machine did you use as a build server for the build runtime benchmarks in your book?
From your experience, did you come across any behavioral Verilog designs that has an explicit control-flow structure which is not flattened.
HLS tools heavily use loop constructs.
100 Power Tips For FPGA Designers
Hope you are fine. This is easy to see because you can model the effect of while or for loops using only if-then-else and switch casebut in a data-encoded way. I think exact behavior and limitations are not part of the specification, and depend on the synthesis tool.
Hello Evgeni, Many thanks for your ideas and references. This book is a collection of articles on various aspects of FPGA design: Can you please give me a small example say a FSM, or a counter and help me to understand that how is control flow in Verilog is encoded in data-driven way?
September 22nd, at September 28th, at Please correct me if I am wrong. Perhaps the ratio of registers to LUTs is going to be higher in data-path intensive designs.
Any questions, comments, suggestions about the book are welcome.

Hi Rajdeep, Such a control-path intensive design might also have a lot of control logic with FSMs inside the datapath. Subscribe to comments feed. October 13th, at I do have one question. But not all control-path and data-path mixed model of designs reflects this characteristics due to design complexity. Deskgners Evgeni, Many thanks for your reply.
