I think you are thinking on the right lines. I would recommend you to read Himanshu Bhatnagar book for more details. The book is Advanced ASIC Chip synthesis?, Second Edition, Kluwer Academic Publishers
Hi, BASICS!! This is the point you have to be strong at. Go through 0) HDLS (Strong design/verif skills) 1) FPGA Design flow (Flow chart). 2) Definations like synthesis, CPLD, FPGA, P n R...... 3) Tools that you have used.(Versions) 4) Projects that you have carried out. Very important 5) CMOS knowledge ( Basic) 6) (power, AreA, Speed,
Hi, all, I have mips.v (register level verilog code) and a tcl script of design compiler. For applying clock gating, I add such a command set_clock_gating_style -minimum_bitwidth 2 in my script. but, after the synthesis, the power report is still the same as that without that command. Do you know what is the reason or my method for app
Hello, Can i use spyglass with netlist after synthesis? Thanks.
usually you can first synthesis with only the low Vt cells, then optimize it, it will replace some of the non-critical cells with high Vt cells so that it can reduce the leakage power, and meet the timing requirement at the same time.
Can you give the area of the different synthesis ?
multiple gate offers choices for the synthesis tool. a mux can be implemented by and gates and inverters, but when a mux is present in the library, it will be efficient in terms of area, power, speed, as compared to a mux which is synthesized using and gate and inverters. Hence so many cells in the library. Kr, Avi
Run a sim in Modelsim (or any other simulator than can create a VCD file, which is pretty much all of them) - then feed the results back in to your synthesis tool to do the power esimate.
Dear all, In my design, total power consumption estimated after synthesis by Cadence-BuildGates is: Internal Cell + Leakage + Net = 0.2904 + 3.9775 + 0.3833 = 4.6512 mW While, after place-and-route, Cadence-Encounter reports: Total leakage power = 337395.002511uW Can anyone tell me why there may be such a diffence? what (...)
Hi, 1- I don't know important of libraries in synthesis and What's different of libraries in synthesis?? 2- I need libraries for Leonardo-spectrum , please send me these. thanks. Refer to Library Compiler & Design Compiler & power Compiler for more details ... The simplest explaination is : Library i
Hi, I have several papers for you 1st one is "synthesis of a compound T-junction for a two-way splitter with arbitrary power ratio" 2nd one is "The modified stepped waveguide T-junctions and the method of initial design" 3rd paper is "Design of unequal H-plane waveguide-power dividers for array applications" at
Another good application is voltage booster design, data communication and sound synthesis.
.lib file contains the following all parameter units like area, time power...(in um, ns, nw) the timing and power information of the different gates. wire load model(like 10x10, 20x20...) operating conditions(PVT) these information is used in the synthesis process using library compiler .lib fiile is converted into synopsys data (...)
Hi deepavlsi, Oh my, you've broken nearly every synthesis rule in the book! In addition to FvM's suggestions, try this: module top (clk, start, x, y, result, done); input clk; // we will do one multiply per clock input start; // begin the calculation input x; // input valu
Another option -- The Xpower Estimator spreadsheets are useful for getting a quick estimate of power consumption prior to synthesis, assuming you fill in the blanks with reasonably good guesses about your design. They run in Microsoft Excel. Maybe that will help you.
hi, i need to calculate the area consumed and power consumption.but these are not directly given in the synthesis report or PR report. whether routing resources mean the no of slices,FF etc what we get in the synthesis report? tomasulo,plz eloborate floorplanner editor. thx. Added after 5 hours 46 minutes:[/colo
In short, Advantage: save power Disadvantage: difficult to manage the timing during synthesis and STA . Besides, if something wrong, it's also hard to debug :(
Many synthesis tools don't support integer division/modulus/remainder unless the calculation is trivial, such as division by a power of two. If your value isn't a power of two, then you are probably out of luck. Maybe you can use another approach such as building your own math module, or using a math core from your software's IP library.

To learn SoC Encounter, you must first learn the Physical Design Flow. You can get this info from the ASIC book. Next, we need the following files to get started.. 1. Verilog Code/Netlist 2. Technology Library Files (Standard Cells Library, like TSMC) 3. Constraint files for Clock Tree synthesis, timing , power etc. If you dont have a Veril
when i run the script of estimation the power from power compiler synopsys i get " Warning: In design 'natencoder', port 'data' is not connected to any nets. (LINT-28)" and data is my input and in modelsim it works correctly and when synthesis it with Leonardo it connected but synopsys says that all of my input disconect .
